Preparing MPSM-T3E3-155 and MPSM-16-T1E1 Cards and Lines for Communication


This chapter describes how to prepare MPSM-T3E3-155 and MPSM-16-T1E1 cards and lines for communications with other switches and customer premises equipment (CPE) by using the command-line interface (CLI).

These topics describe how to prepare MPSM-T3E3-155 and MPSM-16-T1E1 cards and lines for communication:

Quickstart Provisioning Procedures

General MPSM Provisioning Procedures


Note Before you can bring up lines and configure connections, you must first complete the general switch configuration procedures described in the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2.


Preparing for Provisioning

Before you begin configuring lines and ports on MPSM-T3E3-155 and MPSM-16-T1E1 service modules, you need to initialize the cards you plan to provision. Then you should develop and implement a plan for the card and line redundancy options available for each service module. This plan determines how service modules and their back cards must be installed in the chassis, and how lines must connect to the cards before software configuration starts. Without a plan developed for these services, a configuration change for any of these services has the potential to interrupt service and can require substantial configuration teardown.

The MPSM-T3E3-155 card supports 1:1 card redundancy, and the MPSM-16-T1E1 card supports both 1:1 and 1:N card redundancy. The MPSM-T3E3-155 card supports both intercard and intracard APS.

The MPSM-T3E3-155 and MPSM-16-T1E1 service modules also require the management of feature licenses. The required feature licenses are described in "MPSM Feature Licenses".

For instructions on initializing cards, configuring card and line redundancy, and managing MPSM feature licenses on the PXM processor card, refer to the:

Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2.

Selecting and Viewing Service Class Templates

Setting Up Lines

Establishing Redundancy Between Two Lines with APS

Channelizing MPSM-T3E3-155 SONET, SDH, and DS3 (T3) Lines

Setting the Service Context on MPSM-T3E3-155 and MPSM-16-T1E1 Cards

Selecting and Viewing Service Class Templates

These topics and procedures describe selecting and viewing Service Class Templates on the MPSM-T3E3-155 and MPSM-16-T1E1 cards:

Overview of Service Class Templates

MPSM Service Class Templates

Selecting a Card SCT

Selecting a Port SCT

Overview of Service Class Templates

A Service Class Template (SCT) is a file that contains default configuration data for switch connections and for configuring the hardware to support connections. When you configure a connection, or when an SVC is established, the switch analyzes the connection setup request data, any local configuration data, and the SCTs that apply to the port and to the card. For example, if an SPVC configuration does not include required data for the requested class of service (COS), default values from the SCT files are used. If an SVC request or SPVC configuration specifies configuration values that are different from the SCT values, the specified values override the default SCT values.

There are two types of SCTs: card SCTs and port SCTs. Card SCTs define configuration parameters for the hardware that transfers data between the a service module and the switch back plane. You can assign one card SCT to each service module.

Port SCTs define configuration parameters for the hardware that transfers data between a service module and a communication line to another switch or CPE. Port SCTs are assigned when a port is configured, and you can use different port SCTs on the same card, provided that the port SCT you select is designed for that card type.

Some SCT parameters control the service module hardware, and others are used as default values for connection parameters. A complete discussion of the SCT parameters is beyond the scope of this book.

SCT parameters are used to do the following:

Connection policing.

Connection admission control (CAC).

Provide default connection parameters.

Provide connection threshold parameters.

Set up class of service buffer (COSB) parameters and threshold values.

SCTs simplify configuration by providing default values that will work for most connections. This reduces the number of parameters that need to be defined when setting up connections. Without SCTs, you need to perform a lot of detailed manual configuration on each and every port on the switch. This is time consuming and error prone. Typically, traffic profiles are defined by a handful of traffic engineering experts who understand the service level agreements and expected traffic pattern on the ports. These experts define the SCTs for each port in the system. Once the SCT is applied on the port, you do not need to (re)configure the switch. The parameters in the SCTs define generic thresholds and priorities of queues that can be understood without having to go through the programming details of Queuing engines, such as QE1210.

When configuring a service module card SCT, your goal should be to select the card SCT that will support the majority of planned connections on that card. When configuring a service module port SCT, your goal should be to select the port SCT that supports the majority of planned connections on that port.

Each service module contains default SCT parameters that you can use for communications. Cisco also supplies additional SCTs that you can use to better support communications. If none of the Cisco supplied SCTs meet your needs, you can use Cisco WAN Manager (CWM) to create your own custom SCTs. You can not create or modify SCT files using the CLI. For more information on configuring SCTs and SCT parameters, refer to the Cisco WAN Manager User's Guide, Release 15.1.

For information on downloading, registering, and managing SCTs on the PXM card, refer to the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2

MPSM Service Class Templates

SCT files are applicable to the MPSM-T3E3-155 and MPSM-16-T1E1 cards. Each SCT is classified by card or service module type, by whether it is a card or port SCT, and as either policing or non-policing. Although card SCTs may contain policing parameters, these parameters are ignored. Typically, policing SCTs are used on UNI ports at the edge of the ATM network and control traffic entering the network. Non-policing SCTs are typically on trunk ports that interconnect switches within the network.


Note If traffic is properly controlled at the edges of an ATM network, there should be no need for policing within the network.


Table 2-2 lists the SCTs supplied by Cisco for the MPSM-T3E3-155 and MPSM-16-T1E1 cards. For the very latest information on Cisco SCTs, refer to the Release Notes for Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830 Switches, Release 5.2.00

Note For information about managing card and port SCTs on MPSM-T3E3-155 and MPSM-16-T1E1 cards, refer to Chapter 6, "Card Management on MPSM-T3E3-155 and MPSM-16-T1E1".


Selecting a Card SCT

A card SCT defines the queue parameters for the destination slot based cell queues towards the backplane. The same card SCT may be used for multiple cards of the same card type.

When an MPSM-T3E3-155 or MPSM-16-T1E1 card is powered up for the first time, the default card SCT file is used. The default SCT file is 0.


Note For information about managing card SCTs on MPSM-T3E3-155 and MPSM-16-T1E1 cards, refer to the "Managing Card SCTs" section on page 6-9.


Selecting a Port SCT

A port SCT defines queue parameters that apply to egress queues on a port. You can use the same port SCT for multiple ports. Port SCTs can be changed with connections provisioned on the port. However, the port needs to be administratively down to effect this change. Hence this is service affecting.


Note For information on managing port SCTs on MPSM-T3E3-155 and MPSM-16-T1E1 cards, refer to the "Managing Port SCTs" section on page 6-15.


Setting Up Lines

The first step in configuring MPSM-T3E3-155 and MPSM-16-T1E1 lines is to bring up and configure the physical lines that are connected to the switch. These topics describe how to do the following tasks:

Bringing Up Lines

Configuring DS1 (T1) Lines

Configuring E1 Lines

Configuring DS3 (T3) Lines

Configuring E3 Lines

Configuring SONET/SDH Lines

Verifying Line Configuration

Bringing Up Lines

Installing an MPSM-T3E3-155 card can add from 1 to 3 lines to your switch. Installing an MPSM-16-T1E1 card can add from 1 to 16 lines. You must bring up a line before you can configure the line or provision services on the line.

Before a line is brought up, or after it is brought down, the switch does not monitor the line. The port status light for the line flashes green, and all line alarms are cleared. The flashing green light means the line is unprovisioned.

When you bring up a line, the switch starts monitoring the line. The port status light is green when physical layer communications are established with a remote switch. If physical layer communications problems are detected, the port status light turns red, and alarms are reported.


Note APS protection lines for intracard redundancy should be left down. APS automatically brings up each line at the appropriate time. For general information on APS line redundancy, refer to the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2. For information on configuring APS lines, see the "Establishing Redundancy Between Two Lines with APS" section later in this chapter.



Note On the OC3 back cards (the SFP-2-155 and the SMB-2-155-EL), line 2 is always reserved for APS.



Tip To minimize the number of alarms and failed port status lamps (which display red), keep lines down until they are ready for operation.


To bring up a line on the switch, use the following procedure.


Step 1 Establish a configuration session using a user name with GROUP1 privileges or higher.

Step 2 Select the card on which you want to bring up a line with the cc command.

M8850_NY.7.PXM.a > cc <slotnumber>

Replace <slotnumber> with the number of the slot in which the card is installed. Valid slot numbers are as follows:

Cisco MGX 8850 (PXM1E/PXM45) — slots 1-6, 9-14, 17-22, and 25-30.

Cisco MGX 8830 — slots 3-6 and 10-13.

Verify your card selection by viewing the switch prompt, which should list the slot number and the card type.

Step 3 Enter the upln command after the switch prompt.

M8850_NY.13.MPSM155[ATM].a > upln <bay.line>

Replace <bay> with 1, and replace <line> with the number that corresponds to the back card port to which the line is connected, as shown in the following example:

M8850_NY.13.MPSM155[ATM].a > upln 1.1

Note The bay number is always 1.


Step 4 Enter the dsplns command to ensure the appropriate line is in the "Up" state.

M8850_NY.13.MPSM155[ATM].a > dsplns
Medium Medium
Sonet Line Line Line Frame Line Line Valid Alarm APS Channe-
Line State Type Lpbk Scramble Coding Type Intvls State Enabled lized
------------- ----- ------------ ------ -------- ------ -------- ------ -------- ------- -------
1.1 Up sonetSts3c NoLoop Enable NRZ ShortSMF 2 Clear Disable No
1.2 Down sonetSts3c NoLoop Enable NRZ Other 0 Clear Disable No

The line state column shows whether each line is up or down. The line state is the administrative intent for the line. For example, a line is reported as Down until an administrator brings up the line. Once the administrator brings up the line, the line state remains Up until the administrator brings the line down with the dnln command.

The alarm state indicates whether the line is communicating with a remote switch. When the alarm state is reported as Clear, the physical devices at each end of the line have established physical layer communications. ATM or Frame Relay connectivity is established later when interfaces or ports are configured on the line.


Configuring DS1 (T1) Lines

All line types are brought up with a default configuration. When configuring trunks between two Cisco MGX switches, you may be able to accept the defaults for each switch and thus minimize configuration time. When configuring a line to another type of device, ensure that both devices are using the same configuration parameters on the shared line.

The following procedure describes how to configure T1 lines.


Step 1 Establish a configuration session using a user name with GROUP1 privileges or higher.

Step 2 If you do not know the line number you want to configure, enter the dsplns command to display a list of the lines.

M8850_NY.13.MPSM16[FR].a > dsplns

Remember that you cannot configure a line until you have brought it up as described in the previous section, "Bringing Up Lines".

Step 3 To display the configuration for a line, enter the dspln command. For example:

M8850_NY.13.MPSM16[FR].a > dspln 1.1

For more information, see "Verifying Line Configuration", which appears later in this chapter.

Establishing Redundancy Between Two Lines with APS

The Cisco MGX switch supports two types of line redundancy:

Intracard redundancy, where the working and protection lines are connected to the same card.

Intercard redundancy, where the working line is connected to the primary card, and the protection line is connected to the secondary card.

The MPSM-T3E3-155 card supports APS when using the SFP-2-155 or SMB-2-155-EL back cards. APS is not supported on the MPSM-16-T1E1 card.

These topics describe how to add redundancy for these types of APS lines:

Adding Intracard APS Lines on the Same Card

Adding Intercard APS Lines on Different Cards

Adding Intracard APS Lines on the Same Card

To establish redundancy between two lines on the same card, use the following procedure.


Step 1 Establish a configuration session using a user name with GROUP1_GP privileges or higher.

Step 2 If you have not done so already, bring up the working line as described in the "Bringing Up Lines" section, which appears earlier in this chapter.

Step 3 Enter the addapsln command as follows:

M8850_NY.13.MPSM155[ATM].a > addapsln <workingIndex> <protectIndex> <archmode>

Replace <workingIndex> with the location of the working line using the format "slot.bay.line." For example, to specify the line on card 2, line 2, enter 2.1.2.


Note The bay number is always 1.


Replace <protectIndex> with the location of the protection line, using the same format used for the working line.


Note For intracard redundancy, the working index and protection index must specify ports on the same card, so the slot number will always match.


Replace <archmode> with the option number that selects the automatic protection switching (APS) architecture mode (or protocol) you want to use. Table 2-8 shows the option numbers and the architecture modes they select, and whether that mode is revertive.

Table 2-8 APS Line Architecture Modes

Option
Description
Revertive

1

Selects 1+1 signaling (transmission on both working and protect lines) for intracard APS.

Yes

2

Selects 1:1 signaling (transmission on either the working line or the protect line) for intracard APS.

Yes

3

Selects G.783, Annex B 1+1 signaling.

No.


In the following example, 1+1 APS redundancy is assigned to two lines on the same card:

M8850_NY.13.MPSM155[ATM].a > addapsln 1.1.1 1.1.2 1

Step 4 To display a list of all the APS lines on a card, enter the dspapslns command on the active card.

Step 5 To display information on a specific APS line, enter the dspapsln <slot.bay.line> command on the active card.



Note For information on managing redundant APS lines, refer to the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2


Adding Intercard APS Lines on Different Cards

To establish redundancy between two lines on different cards, use the following procedure.


Note For intercard APS to operate properly, an APS connector must be installed between the two cards. For more information in the APS connector and how to install it, refer to the Cisco MGX 8800/8900 Hardware Installation Guide, Releases 2 - 5.2.



Step 1 Establish a configuration session with the appropriate card using a user name with GROUP1_GP privileges or higher.

Step 2 If you have not done so already, add card redundancy as described in the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2.

Step 3 If you have not done so already, bring up the working and protection lines as described in "Bringing Up Lines".

Step 4 Verify that an APS connector is installed between the cards that host the working and protection lines by entering the dspapsbkplane command.

Step 5 Enter the addapsln command as follows:

M8850_NY.13.MPSM155[ATM].a > addapsln <workingIndex> <protectIndex> <archmode>

Replace <workingIndex> with the location of the working line using the format slot.bay.line. For example, to specify the line on card 2, bay 1, line 2, enter 2.1.2.

Replace <protectIndex> with the location of the protection line, using the same format used for the working line.


Note For intercard redundancy, the working index and protection index must specify ports on different cards. Also, the working line index must identify a line on the primary card.


Replace <archmode> with an option number that defines the type of line redundancy you want to use. Table 2-9 shows the option numbers and the architecture modes (or protocols) they select, and whether that mode is revertive. Note that option 2 (1:1 signaling) is not available for Intercard APS.

Table 2-9 APS Line Architecture Modes

Option
Description
Modes
Revertive

1

Selects 1+1 signaling (transmission on both working and protect lines) for intracard APS.

UNI and Bi-directional

Yes

3

Selects G.783, Annex B 1+1 signaling.

UNI and Bi-directional

No


In the following example, 1+1 APS redundancy is assigned to lines on two different cards:

M8850_NY.13.MPSM155[ATM].a > addapsln 1.1.2 2.1.2 1

Step 6 Enter the dspapsbkplane command on both the standby and active cards to verify that the APS connector is installed properly.


Note This command can show different values for each of the two cards, which indicates the APS connector is seated properly on one card, but not on the other.



Step 7 To display the a list of all the APS lines on a card, enter the dspapslns command.



Note For information on managing redundant APS lines, refer to the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2


Channelizing MPSM-T3E3-155 SONET, SDH, and DS3 (T3) Lines

Bringing Up and Configuring TUG-3s

Overview of Channelization on the MPSM-T3E3-155 Card

The MPSM-T3E3-155 supports clear channel services and channelized lines.


Note The MPSM-T3E3-155 requires a license for channelization. Without a channelization license, you cannot channelize SONET or SDH lines. Enter the dspliccd command to view the feature licenses that have been assigned to or are needed by the MPSM-T3E3-155 card.


If a line is not channelized, it is said to be a clear channel line, and the full bandwidth of that line is dedicated to a single channel or path that carries broadband services.

When a line is channelized, it is logically divided into smaller bandwidth channels called paths. These paths can carry an ATM or Frame Relay payload by themselves, or they can be channelized into smaller bandwidth paths that carry the ATM or Frame Relay payload. The sum of the bandwidth on all paths cannot exceed the line bandwidth. Channelized OC3 lines carry broadband and narrowband services, and channelized DS3 (T3) lines carry narrowband services only.

If you are already familiar with configuring Cisco MGX 8850 switches, you know that most cards provision services (such as ATM or Frame Relay) when assigning ports to a line. When a Synchronous Optical Network (SONET) or Synchronous Digital Hierarchy (SDH) line is channelized, these services are provisioned when assigning a port to a path. Channelized paths are simply a logical layer between the port and the line.

The channelization feature in this release allows the following types of channelization:

Single Optical Carrier-3 (OC-3) line into any combination of STS-1 or STM-0/AU-3 sub-paths, for a total path size of 155.52 Mbps.

Single DS3 line into DS1 sub-paths, for a total path size of 736 Mbps.

A SONET synchronous transport signal (STS) is an electrical signal that gets combined with other electrical signals before being transported over an optical line. An STS-3 path has the same bandwidth as an OC-3 line, but it is not labeled with the OC rating if it is merely a path within a higher bandwidth line. For example, you can configure up to 3 STS-1 width paths in an OC-3 line.

A synchronous transport module (STM) signal is the SDH equivalent of the SONET STS, but the numbers are different for each bandwidth. In this guide, the STM term refers to both path widths and optical line rates. The paths within an STM signals are called Administrative Units (AUs).

Channelizing a line is a two-step process:

Channelize the line into paths

Bring up the individual paths and configure it as required

Because paths support ATM and Frame Relay on different payloads, you need to specify which payload type will travel over each path, and you may want to configure additional options for each payload and path type. The sections that follow describe how to channelize lines, bring up paths, and configure paths.

When a line is brought up initially, there is one path with a width of 3. On a SONET line, a path width of 3 indicates that the line contains one clear channel STS-3 path. On an SDH line, a path width of 3 indicates that the line contains one clear channel STM-1/AU-4. To implement channelization, you need to set the path to the width 1. On SONET lines, a width of 3 results in one path only. On SDH lines, a width 3 path can be channelized into structured Virtual Tributaries (VTs).

MPSM-T3E3-155 Line Channelization

The channelization feature allows you to create a simple or complex combination of paths for each line on your MPSM-T3E3-155 back card. The simplest approach assigns the same bandwidth to each path. For an OC-3/STM-1 line, the simple approach is to configure 1 STS-3/STM-1 path.

A more complex approach creates different path widths within the same SONET/SDH/T3 line. Depending on the type of line being channelized and the channelization scheme used, different types of paths are created.

Table 2-10 lists the SONET, SDH, and T3 path types that are supported in Release 5 of the MPSM-T3E3-155 card.

You can assign ATM service to any level path down to DS1, and you can assign Frame Relay service to any level path down to DS0. For example, an STS-1 path can be channelized into two individual DS1 paths, so that one DS1 path carries ATM service, and the other DS1 path carries DS0s with Frame Relay service.


Note ATM service is carried on an STS-3 down to DS1 or nxDS1 (IMA), where n is the number of configured DS1s. See the "Adding ATM Ports" section Chapter 3, "Provisioning ATM Services on MPSM-T3E3-155 and MPSM-16-T1E1," to configure ATM service to a DS1 line. Frame Relay is carried on STS-3 down to DS1 or nxDS0, where n is the number of configured DS0s. See the "Provisioning Frame Relay Ports" section Chapter 4, "Provisioning Frame Relay Services on MPSM-T3E3-155 and MPSM-16-T1E1," to configure Frame Relay DS1s/DS0s on a line.


Keep the following in mind when configuring paths on a channelized line:

You can not configure channelization on a line that is already carrying active paths. Before you can configure a previously channelized line, you must bring down all previously configured paths on that line with the dnpath command.

You can not configure a channelized line to be in clear channel mode if it is carrying active paths. Before you can configure a channelized line to be clear channel, you must bring down all previously configured paths on that line with the dnpath command.

The sum of the bandwidths on the provisioned physical interfaces can not exceed the total bandwidth of the physical line (OC3 or DS3).

A single STS-1 or AU-3 can carry one E3 or one DS3 (T3).

A single STS-1 or AU-3 can carry either 28 DS1s or 21 E1s. You can not map DS1s (T1s) and E1s into a same STS-1.

All tributaries within an AU-3 (or TUG-3 within AU-4) must be the same size: either VC-11/TU-11 or VC-12/TU-12.

A single TUG-3 in an AU-4 can carry 21E1s, 28 T1s, one E3, or one T3.

A single AU-4 can carry 84 T1s, 63 E1s, 3 T3s, or 3 E3s.

You can not map channelized DS3 lines or paths into VC3/TU-3s, TUG-3s, or AU-4s.

ATM service can be selected at any rate down to DS1/E1 for OC-3/STM-1/T3 interfaces.

Frame Relay service can be selected at any rate down to DS0 for OC-3/STM-1/T3 interfaces.

A single STS-1 will carry one E3 or one T3.

A single SDH VC-11/TU-11s carries a single DS1.

A single SDH TU-12/VC-12 carries a single E1.

Once a line is configured to be channelized, all the paths that it supports come into existence in non-provisioned (down) mode. You must enter the uppath command to bring up the paths you want to configure, and then enter the cnfpath command to configure them. The cnfpath command parameters are different, depending on the type of path you are configuring. When entering the cnfpath command, take care to use only the parameters that are valid for the path type you are configuring. Table 2-12 describes the possible cnfpath command parameters for all path types.

Table 2-12 cnfpath Command Parameters 

Parameter
Description

-<path filter>

Keyword that specifies the type of path you are configuring. That possible path types are as follows:

-sts: sts/au path

-ds3: ds3 path

-e3: e3 path

-vt: vt/TU path

-ds1: ds1 path

-e1: e1 path

<path_id>

Specifies the path you are configuring.


Note Enter the dsppaths -all command to see the path numbers for all paths on the current MPSM-T3E3-155 card.



Note Only bay 1 is supported for MPSM-T3E3-155 cards.


-payload
<sts_au_payload_type>

Specifies the payload type. Enter a the appropriate number that corresponds with the payload type you want to set, as follows:

2 = unspecified. Use this option to concatenate channelized paths into a single path.

3 = ds3

4 = vt15vc11

5 = vt2vc12

8 = e3

9 = vtStructured. This option only available for SDH lines that configured for a single path (width 3).


Note You can assign ds3 payloads only to sts1_stm0 paths.


-width
<width_spec>

Specifies the width of the path. For the MPSM-T3E3-155 card, the options are as follows:

1 = OC3 is channelized into three STS-1/STM-0 (AU-3) paths.

3 = OC3 contains one STS-3/STM-1 (AU-4) path. This is the default setting.

Note This parameter is available only for SONET/SDH lines that are in a down state.

-txtrace
<trace-string>

For SONET/SDH and E3 paths, this option allows you to transmit and display trail trace bytes. You can test the line by transmitting a group of numbers using cnfln -txtrace and then displaying the result using the dshpln command to see if the numbers are the same. Enter the keyword (-txtrace) followed by the TraceString.

On SDH and E3 lines, the TraceString is a number that can be a maximum of 15 bytes.

ON SONET lines, the TraceString is a number that can be a maximum of 62 bytes.

For example:

-txtrace 1736297:

-cb
<AIScBitsCheck>

For DS3 paths, this option specifies whether to ignore or check the AIS C-bit.

1-Chk C-bit

2-Ignore C-bit

-oof
<OOF Criteria>

For DS3 paths, this option specifies the threshold for triggering an out-of-frame condition. Enter the keyword (-oof) followed by the OOFCriteria identifier. For example:

-oof 1

The possible values for this parameter are:

1 = 3 out of 8. An out-of-frame condition is declared if at least 3 out of 8 framing bits are in error.

2 = 3 out of 16. An out-of-frame condition is declared if at least 3 out of 16 framing bits are in error.

-lt
<Line Type>

For DS3, E3, DS1, and E1 paths, this option specifies the line type you are configuring. Enter the keyword (-lt) followed by the LineType identifier. For example:

-lt 2

E1:

4 = dsx1E1

5 = dsx1E1CRC

6 = dsx1E1MF

7 = dsx1E1CRCMF

-clk
<Clock Source>

For DS3, E3, DS1, and E1 paths, this option determines whether the transmit clock comes from the backplane (local timing) or the receive clock on the line (looped timing). Enter the keyword (-clk) followed by the clockSource identifier. For example:

-clk 2

The possible values for this parameter are:

1 = loopTiming source—The receive clock on the back card is redirected to become the transmit clock source.

2 = localTiming source (default)—The clock source from the backplane functions as the transmit clock source.

-feac
<RcvFEAC>

For DS3 and E3 paths, this option specifies the threshold for triggering an FEAC condition. Enter the keyword (-feac) followed by the RcvFEAC identifier. For example: -feac 1

The possible values for this parameter are:

1 = 4 out of 5

2 = 8 out of 10

3 = disable

-lpb
<Loopback>

For DS3, E3, DS1, and E1 paths, this option specifies the loopback type for the line type. The entry for no loopback (1) removes any existing loopback.

1 = No loopback

2 = Local loopback

3 = Remote loopback

-chan
<Channelization>

For DS3 paths, this option enables or disables channelization on the current line. Enter the keyword (-chan) followed by the channelization identifier. For example:

-chan 2

The possible values for this parameter are:

1 = Disabled

2 = Enabled


Channelization in SDH Networks versus SONET Networks

SONET networks and SDH networks use different terminology to describe the same elements in a channelized line. Table 2-13 lists the SONET terms and their equivalent SDH terms.

Note The bay is always 1.



Tip Enter the dsppaths -all command to see the path identifies for all paths on the current card.


VTG and TUG-3 Configuration Elements

When OC3/STM-1 lines are channelized to carry tributaries, the tributaries are grouped together in a logical entity called a tributary group. In SONET networks, the tributary groups are called virtual tributary groups (VTGs). In SDH networks, the tributary groups are called Tributary Unit Groups (TUGs). Each individual VTG or TUG is a manageable path with a defined rate and format.


Note TUGs and VTGs are not interfaces, and cannot be monitored for faults and performance.


In SONET networks, a single STS-1 line carries 7 separate VTGs. Each individual VTG can be configured independently from the other VTGs in that same STS-1, and can carry VTs of any size.

In SDH networks, a single STM-1 (AU-4) line carries 3 separate TUG-3s. Each individual TUG can be configured independently from the other TUGs in that same STM-0, and can carry TUs of any size.

Table 2-16 summarizes the elements tributary group configuration.

Channelized Line Examples

The sections that follow provide examples of channelized DS3, SONET, and SDH lines.


Note There are several options for channelizing lines, depending on your network needs, as long as the total path size remains within the physical lines total bandwidth limit. The purposes of the examples that follow is to provide a basic idea of how channelization is configured for the different lines.


Example of a Channelized DS3 line

Figure 2-1 shows one possible way to channelize a DS3 line down to DS1 paths. In this example, the DS3 is mapped into 3 AU-3 (STM-0) paths. The paths are mapped as follows:

The DS3 line is channelized into twenty-eight individual DS1 paths.


Note The purposes of this example is to provide a basic idea of how channelization is configured on a DS3 line. Therefore, Figure 2-1 shows the configuration for only five of the twenty-eight DS1 paths. Note that when you enable channelization on a DS3 line, twenty-eight DS1 paths are created and put in a Down state.


DS1 path 1.1.1:1 is channelized into DS0s on a Frame Relay port.

DS1 path 1.1.1:2 ends at a Frame Relay port.

DS1 paths 1.1.1:3 and 1.1.4 are grouped into a single IMA group on an ATM port.

DS1 path 1.1.1:5 ends on a Frame Relay port.

Figure 2-1 Example of a Channelized DS3 line.

Example of a Channelized OC3 SONET line

Figure 2-2 shows one possible way to channelize a OC3 line down to DS0. In this example, the OC3 is channelize into 3 STS-1 paths. The paths are mapped as follows:

The OC3 SONET line is channelized into three individual STS-1 paths.

STS-1 path 1.1.1 provides direct ATM service over a single path.

STS-1 path 1.1.2 provides Frame Relay service to three ports. In this case, the STS-1 path is channelized into a single DS3 path, which is then channelized into two separateDS1 paths. One DS1 path ends connects directly to a Frame Relay port, while the other DS1 path is channelized into two separate DS0s that connect to Frame Relay ports.

STS-1 path 1.1.3 provides ATM IMA service to an ATM Port. STS-1 path 1.1.3 is channelized into twenty-eight VT 1.5 paths. Each VT 1.5 path carries a DS1 path. The DS1 paths are bundled into an IMA group that ends at an ATM port.


Note The purposes of this example is to provide a basic idea of how channelization is configured on a SONET line. Therefore, Figure 2-2 shows the configuration for only two of the twenty-eight DS1 and VT 1.5 paths in each instance.


Figure 2-2 Example of a Channelized SONET.

Example of a Channelized OC3 SDH line

Figure 2-3 shows one possible way to channelize a OC3 line down to DS1 paths. In this example, the OC3 is channelize into 3 AU-3 (STM-0) paths. The paths are mapped as follows:

The OC3 SONET line is channelized into three individual AU-3 (STM-0) paths.

AU-3 (STM-0) path 1.1.1 carries a DS3 path that ends at an ATM port.

AU-3 (STM-0) path 1.1.2 is channelized into twenty-eight individual TU-11s. Each TU-11 carries a single DS1 path. Two of DS1 paths are combined into an IMA group that ends at an ATM port. The other TU-11 ends at a Frame Relay port.

AU-3 (STM-0) path 1.1.3 is channelized into a single TU-12 path, which is further channelized into 21 E1 paths that end at a Frame Relay port.


Note The purposes of this example is to provide a basic idea of how channelization is configured on an SDH line. Therefore, Figure 2-3 shows the configuration for only three of the twenty-eight TU-11s and DS1s on the AU-3 path 1.1.2, and path 1.1.3 shows only one E1 path.


Figure 2-3 Example of a Channelized SDH OC3 line

Channelizing a DS3 Line

When a DS3 line is in clear channel mode, it carries a single DS3 path. You can channelize the DS3 line so that it contains three separate DS1 paths.


Note Use this procedure to channelize and configure a physical DS3 line on a BNC-3-T3 back card only. If you want to further channelize a SONET or SDH DS3 path, follow the procedures in the "Bringing Up and Configuring a DS3 (T3) Path" section later in this chapter.


Use the following procedure to channelize a DS3 line into twenty-eight DS1 paths.


Step 1 Establish a configuration session using a user name with GROUP1_GP privileges or higher.

Step 2 Enter the cc command to change to the card you want to configure.

Step 3 If you have not done so already, bring up the line to be configured as described in the " Bringing Up Lines" section, which appears earlier in this chapter.

Step 4 Enter the dsplns command to ensure that the line you want to channelize is up, and to obtain the line number, as shown in the following example:

M8830_CH.12.MPSM155[ATM].a > dsplns
Line Line Line Line Length OOF AIS Valid Alarm
Num State Type Lpbk (meters) Criteria cBitsCheck Intvls State
---- ----- --------------- ---------- -------- ----------- ---------- ------ ----------
1.1 Up dsx3CbitParity NoLoop 0 3Of16Bits Check 96 Clear
1.2 Up dsx3CbitParity NoLoop 0 3Of16Bits Check 25 Clear
1.3 Down dsx3CbitParity NoLoop 0 3Of16Bits Check 0 Clear

Step 5 Enter the cnfln <bay.line> -chan 2 command to configure a valid line type for channelization. Replace bay.line with the DS3 line number in the format 1.n, where n is the number of the line you want to channelize. The -chan 2 option channelizes the line into twenty-eight individual DS1 sub-paths.


Note The bay number is always 1.



Note 9 and 11 are the only valid line types for channelized DS3 lines.


In the following example, the user configures line 1.2 with the line type dsx3CbitParity.

M8830_CH.12.MPSM155[ATM].a > cnfln 1.2 -lt 11 -chan 2

Step 6 Enter the dsppaths -all or dsppaths -ds1 command to ensure that the DS3 line has been channelized into twenty-eight individual DS1 sub-paths. The DS1 lines will have path numbers in the following format: bay.line.ds1, where bay.line is the number of the DS3 line you channelized in Step 5, and ds1 identifies the individual DS1 path.

In the following example, the user enters the dsppaths -all command to display all paths on the current card.

M8830_CH.12.MPSM155[ATM].a > dsppaths -all

1.2:28 ds1 Down dsx1ESF NoLoop Unknown Down invalid

Step 7 Bring up and configure the individual DS1 paths as described in the "Bringing Up and Configuring DS1(T1) and E1 Paths" section later in this chapter.


Channelizing a SONET Line

When a SONET line is in clear channel mode, it carries a single STS-3 path. You can channelize the SONET line so that it contains three separate STS-1 paths.

Use the following procedure to channelize a SONET line into three STS-1 paths.


Step 1 Establish a configuration session using a user name with GROUP1_GP privileges or higher.

Step 2 Enter the cc command to change to the card you want to configure.

Step 3 If you have not done so already, bring up the line to be configured as described in the " Bringing Up Lines" section, which appears earlier in this chapter.

Step 4 Enter the dsppaths -sts command to see the path ID numbers for all STS-1 paths on the current card, and obtain the path ID for the path you want to channelize.

Step 5 Enter the cnfpath -sts <path_id> -width 1 command to set the path width. Although this command has many options, you must channelize the line before you bring up and configure individual paths. The command form that channelizes the line is as follows:

M8850_NY.13.MPSM155[ATM].a > cnfpath -sts <path_id> -width 1

Replace the path_id variable with the complete path number in the format bay.line.sts, as shown in Table 2-12.


Note The MPSM-T3E3-155 card supports two widths: STS-1/STM-0 and STS-3/STM-1. To channelize the line, you must select STS-1/STM-0. For more information about the
-width <width_spec> parameter, see Table 2-12.


The following example channelizes line 1.1.1 into three individual STS-1 paths.

M8850_NY.13.MPSM155[ATM].a > cnfpath 1.1.1 -width 1

Step 6 Enter the dsppaths -sts command to verify that the line has been channelized into three separate STS paths, as shown in the following example.


M8850_NY.13.MPSM155[ATM].a > dsppaths -sts

Path Path Admin Path Path Alarm Oper
Type Status Payload Width Status State
-------- -------- -------- ------------- ------- --------- ------
1.1.1 sts Down unequipped 1 Unknown Down
1.1.2 sts Down unequipped 1 Unknown Down
1.1.3 sts Down unequipped 1 Unknown Down

M8850_NY.13.MPSM155[ATM].a >



Note The software supports only the path widths described in Table 2-12. When you create a path by dividing a larger path or combining smaller paths, the software may automatically create additional paths to assure that all the available bandwidth is assigned to one of the available path sizes.



Note To change the path width on a line that has already been configured to support a path width of 1, enter the dnpath -sts <path_id> command to bring down the path, and then enter the cnfpath -sts <path_id> -width 3. Note that all sub-paths must be in a down state before you can bring down a parent path.


Bringing Up and Configuring SONET Paths

After you split a SONET line into multiple paths, you are ready to bring up the individual paths. You must bring up the individual path or paths before you can assign a payload to that path and proceed with further channelization. Once you assign a payload to a path, the path is channelized into separate paths.

The following procedures describe how to bring up path and configure the path for one of the following payload types:

DS3—If the users chooses the payload to be ds3, then a single DS3 path is created and put in a DOWN state.

E3—If the users chooses the payload to be e3, then a single E3 path is created and put in a DOWN state.

VT 1.5—If the users chooses the payload to be VT 1.5, then 28 VT 1.5 paths and 28 DS1 paths are created and put in a DOWN state.

VT 2.0—If the users chooses the payload to be VT 2.0, then 21 VT 2.0 paths and 21 E1 paths are created and put in a DOWN state.

Structured VT (SDH and width 3)—This option is not supported on SONET lines.

Use the following procedure to bring up and configure a SONET path.


Step 1 Establish a configuration session using a user name with GROUP1_GP privileges or higher.

Step 2 Enter the cc command to change to the MPSM-T3E3-155 card you want to configure.

Step 3 If you have not done so already, channelize the line as described in the previous section, "Channelizing a SONET Line"

Step 4 Enter the dsppaths -sts command to see the path ID numbers for all STS-1 paths on the current card, and obtain the path ID for the path you want to channelize.

Step 5 Bring up the path with the uppath -sts <path num> command, as shown in the following example.

M8850_NY.13.MPSM155[ATM].a > uppath -sts 1.1.1

Step 6 Enter the cnfpath -sts <path_id> -payload <sts_au_payload_type> command to set the payload type for the path. The possible payload types for the paths you can create are described in Table 2-12. Be sure to set the payload to a type that is appropriate to the path type you are channelizing.


Note Table 2-12 describes the path_id variable, which must be entered in the format bay.line.sts. The -payload option specifies the payload type as DS3, E3, VT 1.5, VT 2.0, or unspecified.


The following example shows how to configure a path for a DS3 payload:

M8830_CH.12.MPSM155[ATM].a > cnfpath -sts 1.4.47 -payload 3

Step 7 To display the status of a path you have brought up, enter the dsppath command as follows:

M8830_CH.12.MPSM155[ATM].a > dsppath 1.4.47
Path Number : 1.4.47 Path Type : sts
Payload : ds3 Width : 1
Admin Status : Up Alarm Status : Clear
Path Operational State : lowLayerDn
Number of ports : 0 Number of partitions: 0
Number of SPVC : 0 Number of SPVP : 0
Number of SVC : 0
Xmt.Trace :

When the path is up, the Admin Status row displays Up. The Payload row displays the payload type.

Step 8 Bring up and configure the paths you created in Step 5. Refer to the section that is appropriate to the payload you configured, as follows:

If you configured a DS3 payload, see the "Channelizing a DS3 Line" section later in this chapter for instructions on bringing up and configuring DS3 paths.

If you configured an E3 payload, see the "Bringing Up and Configuring E3 Paths" section later in this chapter for instructions on bringing up and configuring E3 paths.

If you configured a VT 1.5 or VT 2.0 payload, see the "Bringing Up and Configuring TUG-3s" section later in this chapter for instructions on bringing up and configuring VT paths. To bring up and configure the 28 DS1s that were also created when you set the payload as VT 1.5, see the "Bringing Up and Configuring DS1(T1) and E1 Paths" section later in this chapter.

If you configured a VT 2.0 payload, see the "Bringing Up and Configuring TUG-3s" section later in this chapter for instructions on bringing up and configuring VT paths. To configure the 21 DS1s that were also created when you set the payload as VT 2.0, see the "Bringing Up and Configuring DS1(T1) and E1 Paths" section later in this chapter.


Channelizing an SDH Line

When an SDH line is in clear channel mode, it carries a single AU-4 path. You can channelize the AU-4 path into three separate AU-3 paths.


Note STM/AU paths on SDH lines are equivalent to STS paths on SONET lines. The Release 5 CLI shows SONET naming conventions in the place of their equivalent SDH terms. Note that in the channelization CLI, the STM/AU paths are called "STS" paths.


The following procedure describes how to channelize an SDH line into three separate STM-0/AU-3 paths.


Step 1 Establish a configuration session using a user name with GROUP1_GP privileges or higher.

Step 2 Enter the cc command to change to the MPSM-T3E3-155 card you want to configure.

Step 3 If you have not done so already, bring up the line to be configured as described in the " Bringing Up Lines" section, which appears earlier in this chapter. Once a line is brought up, a single AU-4 path is created and put in a down state.

Step 4 Enter the dsppaths -all command to ensure that an AU path has been created, and to obtain the path_id for the path.

M8850_NY.13.MPSM155[ATM].a > dsppaths -all

Path Path Admin Path Path Alarm Oper
Type Status Payload Width Status State
-------- -------- -------- ------------- ------- --------- ------
1.1.0 sts Down unequipped 3 Unknown Down
Shelf Database table empty.SonetVTsTable
Shelf Database table empty.Ds3PathsTable
Shelf Database table empty.Ds1PathsTable

If want to channelize the AU-4 path into three smaller AU-3 paths, proceed to Step 5. If you want to channelize the AU-4 path into clear channel DS3 or clear channel E3 paths, skip the rest of the steps in this section and follow the procedure in the "Bringing Up and Configuring SDH Paths" section that follows.

Step 5 Enter the cnfpath -sts <path_id> -width 1 command to set the path width. Although this command has many options, you must channelize the line before you bring up and configure individual paths. The command form that channelizes the line is as follows:

M8850_NY.13.MPSM155[ATM].a > cnfpath -sts <path_id> -width 1

Replace the path_id variable with the complete path number in the format bay.line.sts, as shown in Table 2-12. The correct path number for unchannelized SDH line 1 on an MPSM-T3E3-155 card is 1.1.0.

The MPSM-T3E3-155 card supports two path widths:

STS-3/STM-1 (otherwise known as AU-4 in SDH terminology) uses the full bandwidth of the line in a single AU-4 path (-width 3). This is the default path width.

STS-1/STM-0 divides the line into three separate AU-3 paths (-width 1).

You must enter -width 1 (STS-1/STM-0) to channelize an SDH path into three separate AU-3 paths. For more information about the width_spec parameter, see Table 2-12.

When you channelize a clear channel line, the cnfpath command channelizes the entire line into paths equal to the path width you specify.

The following example channelizes line 1.1.1 into 3 AU-3 paths.

M8850_NY.13.MPSM155[ATM].a > cnfpath -sts 1.1.0 -width 1

Step 6 Enter the dsppaths -sts command to verify that the line has been channelized into three separate SDH paths, as shown in the following example.

M8850_NY.13.MPSM155[ATM].a > dsppaths -sts

Path Path Admin Path Path Alarm Oper
Type Status Payload Width Status State
-------- -------- -------- ------------- ------- --------- ------
1.1.1 sts Down unequipped 1 Unknown Down
1.1.2 sts Down unequipped 1 Unknown Down
1.1.3 sts Down unequipped 1 Unknown Down



Note The software supports only the path widths described in Table 2-12. When you create a path by dividing a larger path or combining smaller paths, the software may automatically create additional paths to assure that all the available bandwidth is assigned to one of the available path sizes.



Note To change the path width on a line that has already been configured to support a path width of 1, enter the dnpath -sts <path_id> command to bring down the path, and then enter the cnfpath -sts <path_id> -width 3. Note that all sub-paths must be in a down state before you can bring down a parent path.


Bringing Up and Configuring SDH Paths

After you split an SDH line into multiple paths, you are ready to bring up the individual paths. You must bring up the individual path or paths before you can assign a payload to that path and proceed with further channelization. Once you assign a payload to a path, the path is channelized into separate paths

SDH STM-0/AU-3 paths support following payload types:

DS3—If the users chooses the payload to be ds3, then a single DS3 path is created and put in a DOWN state.

E3—If the users chooses the payload to be e3, then a single E3 path is created and put in a DOWN state.

TU-11 (VT 1.5)—If the users chooses the payload to be VT 1.5, then 28 VT 1.5 paths and 28 DS1 paths are created and put in a DOWN state.

TU-12 (VT 2.0)—If the users chooses the payload to be VT 2.0, then 21 VT 2.0 paths and 21 E1 paths are created and put in a DOWN state.

SDH STM-1/AU-4 paths support following payload types:

DS3—If the users chooses the payload to be ds3, then a three DS3 paths are created and put in a DOWN state.

E3—If the users chooses the payload to be e3, then three E3 paths are created and put in a DOWN state.

TU-11 (VT 1.5)—If the users chooses the payload to be VT 1.5, then 84 TU-11s paths and 84 DS1 paths are created and put in a DOWN state.

TU-12 (VT 2.0)—If the users chooses the payload to be VT 2.0, then 63 TU-12s paths and 63 E1 paths are created and put in a DOWN state.

Structured VT— If the users chooses the payload to be structured VT, then three TUG-3s are created and put in a down state. This payload is available only for SDH AU-4 Paths.

Use the following procedure to bring up and configure a SDH path.


Step 1 Establish a configuration session using a user name with GROUP1_GP privileges or higher.

Step 2 Enter the cc command to change to the MPSM-T3E3-155 card you want to configure.

Step 3 If you have not done so already, channelize the line as described in the previous section, "Channelizing an SDH Line"

Step 4 Enter the dsppaths -sts command to see the path ID numbers for all STS-1/STM-0 paths on the current card, and obtain the path ID for the path you want to channelize.

Step 5 Bring up the path with the uppath -sts <path num> command as shown in the following example.

M8850_NY.13.MPSM155[ATM].a > uppath -sts 1.1.1

Step 6 Enter the cnfpath -sts <path_id> -payload <sts_au_payload_type> command to set the payload type for the path. The possible payload types for the paths you can create are described in Table 2-12. Be sure to set the payload to a type that is appropriate to the path type you are channelizing.


Note Table 2-12 describes the path_id variable, which must be entered in the format bay.line.sts. The -payload option specifies the payload type as DS3, E3, VT 1.5, VT 2.0, VT structured, or unspecified.


The following example shows how to configure a path for a DS3 payload:

M8830_CH.12.MPSM155[ATM].a > cnfpath -sts 1.4.47 -payload 3

Step 7 To display the status of a path you have brought up, enter the dsppath command as follows:

M8830_CH.12.MPSM155[ATM].a > dsppath 1.4.47
Path Number : 1.4.47 Path Type : sts
Payload : ds3 Width : 1
Admin Status : Up Alarm Status : Clear
Path Operational State : lowLayerDn
Number of ports : 0 Number of partitions: 0
Number of SPVC : 0 Number of SPVP : 0
Number of SVC : 0
Xmt.Trace :

When the path is up, the Admin Status row displays Up. The Payload row displays the payload type, which is either DS3, E3, VT 1.5, VT 2.0, VT structured or unspecified.

Step 8 Bring up and configure the paths you created in Step 5. Refer to the section that is appropriate to the payload you configured, as follows:

If you configured a DS3 payload, see the "Channelizing a DS3 Line" section later in this chapter for instructions on bringing up and configuring DS3 paths.

If you configured an E3 payload, see the "Bringing Up and Configuring E3 Paths" section later in this chapter for instructions on bringing up and configuring E3 paths.

If you configured a VC-12/TU-12 (VT 1.5) payload, see the "Bringing Up and Configuring TUG-3s" section later in this chapter for instructions on bringing up and configuring VT paths. To bring up and configure the 28 DS1s that were also created when you set the payload as VT 1.5, see the "Bringing Up and Configuring DS1(T1) and E1 Paths" section later in this chapter.

If you configured a VC-12/TU-12 (VT 2.0) payload, see the "Bringing Up and Configuring TUG-3s" section later in this chapter for instructions on bringing up and configuring VT paths. To configure the 21 DS1s that were also created when you set the payload as VT 2.0, see the "Bringing Up and Configuring DS1(T1) and E1 Paths" section later in this chapter.


Bringing Up and Configuring a DS3 (T3) Path

The following procedure describes how to bring up, configure, and channelize a DS3 path into twenty-eight individual DS1 paths.


Note Use this procedure to configure a DS3 path within a channelized SONET or SDH OC3 line only. To channelize and configure a physical DS3 line on a BNC-3-T3 back card, following the procedures in the "Channelizing a DS3 Line" section earlier in this chapter.



Step 1 Establish a configuration session using a user name with GROUP1_GP privileges or higher.

Step 2 Enter the cc command to change to the MPSM-T3E3-155 card you want to configure.

Step 3 If you have not done so already, bring up the line to be configured as described in the " Bringing Up Lines" section, which appears earlier in this chapter.

Step 4 Enter the dsppaths -ds3 command to see the path ID numbers for all DS3 paths on the current card, and obtain the path ID for the path you want to bring up and channelize.

Step 5 If you are configuring a DS3 path on a channelized SONET or SDH line, bring up the ds3 path with the uppath command as follows:

M8830_CH.12.MPSM155[ATM].a > uppath -ds3 <path_num>

If you are configuring a physical DS3 (T3) line that is attached to a BNC-3-T3 back card, you do not need to bring the DS3 path up, and you can skip this step and move on to Step 4.


Step 6 Enter the cnfpath -ds3 <path_id> [optional parameters] -chan 2 command as follows to channelize the DS3 line into 28 DS1 lines.

cnfpath -ds3 <path_id>[-cb <AIScBitsCheck>] [-oof <OOF Criteria>] [-lt <Line Type>] [-clk <Clock Source>] [-feac <RcvFEAC>] [-lpb <Loopback>]-chan 2


Note You must include the optional -chan 2 parameter with the cnfpath command if you want to channelize the DS3 line.



Note Enter the dsppaths -ds3 command to see the path numbers for all T3 (DS3) paths on the current card.


In the example that follows, the user enables channelization on the DS3 line 1.1.1:

M8830_CH.12.MPSM155[ATM].a > cnfpath -ds3 1.1.1 -chan 2

Step 7 To display the status of a path you have brought up, enter the dsppath command.

Step 8 Bring up and configure the individual DS1 paths, as described in the "Bringing Up and Configuring DS1(T1) and E1 Paths" section, later in this chapter.


Bringing Up and Configuring E3 Paths

You must bring up an E3 path before you can provision services on that path.


Note You cannot channelize E3 paths.


The following procedure describes how to bring up a path and configure an E3 path.


Step 1 Establish a configuration session using a user name with GROUP1_GP privileges or higher.

Step 2 Enter the cc command to change to the MPSM-T3E3-155 card you want to configure.

Step 3 If you have not done so already, channelize the line as required. For more information, see the " MPSM-T3E3-155 Line Channelization" section, which appears earlier in this chapter.

Step 4 Enter the dsppaths -e3 command to see the path ID numbers for all E3 paths on the current card, and obtain the path ID for the path you want to bring up and channelize.


Note In Release 5 of the MPSM-T3E3-155 card, the dsppaths/dsppath display shows E3 paths as DS3 paths.


Step 5 Bring up the E3 path with the uppath command as follows:

M8830_CH.12.MPSM155[ATM].a > uppath -e3 <path_num>

Step 6 Enter the cnfpath -e3 command as follows to configure the E3 path parameters.

cnfpath -e3 <path_id> [-lt <Line Type>] [-clk <Clock Source>] [-lpb <Loopback>] [-txtrace <traceString>]

The cnfpath command parameters are described in Table 2-12.


Note Enter the dsppaths -e3 command to see the path numbers for all E3 paths on the current card. Note that, in the Release 5 CLI display, the term "DS3" refers to both E3 and T3 (DS3) lines.


In the following example, the user configures the E3 path 1.1.2 so that it has the line type e3g832frmronly, a local clock source, and no loopback.

M8850_NY.13.MPSM155[ATM].a > cnfpath -e3 1.1.2 -lt 17 -clk 2 -lpb 1

Step 7 To display the status of a path you have brought up, enter the dsppath -ds3 <path_id> command as follows:

M8830_CH.12.MPSM155[ATM].a > dsppath -e3 1.4.4


Bringing Up and Configuring DS1(T1) and E1 Paths

You must bring up a DS1/E1 path before you can provision services on that path. The following procedure describes how to bring up a path and configure channelized DS1/E1 paths.


Step 1 Establish a configuration session using a user name with GROUP1_GP privileges or higher.

Step 2 Enter the cc command to change to the card you want to configure.

Step 3 If you have not done so already, channelize the line as required. For more information, see the " MPSM-T3E3-155 Line Channelization" section, which appears earlier in this chapter.

Step 4 Enter the dsppaths -ds1|e1 command to see the path ID numbers for all T1 (DS1) and E1 paths on the current card, and obtain the path ID for the path you want to bring up and channelize.


Note In Release 5 of the MPSM-T3E3-155 card, the dsppaths/dsppath display shows E1 paths as DS1 paths.


Step 5 Bring up the DS1 or E1 path with the uppath command as follows:

M8830_CH.12.MPSM155[ATM].a > uppath [-ds1|e1] <path_num>

Step 6 Enter the cnfpath -ds1|e1 command as follows to configure the DS1 or E1 path parameters.

cnfpath [-ds1|e1] <path_id> [-lpb <Loopback>] [-lt <Line Type>] [-clk <Clock Source>]

The cnfpath command parameters are described in Table 2-12.


Note The cnfpath command parameters are the same for DS1 and E1 paths.



Note Enter the dsppaths -ds1|e1command to see the path numbers for all T1 (DS1) and E1 paths on the current card. Note that, in the Release 5 CLI display, the term "DS1" refers to both E1 and T1 (DS1) lines.


In the following example, the user configures the DS1 path 1.1.1:1 so that it has local loopback enabled, a dsx1ESF line type, and a local clock source.

M8850_NY.13.MPSM155[ATM].a > cnfpath -ds1 1.1.1:1 -lpb 2 -lt 2 -clk 2

Step 7 To display the status of a path you have brought up, enter the dsppath [-ds1|e1] <path_id> command as follows:

M8850_NY.13.MPSM155[ATM].a > dsppath -ds1 1.1.1:1
Path Number : 1.1.1:1 Path Type : ds1
Admin Status : Up Alarm Status : Clear

Path Service : unspecified Number of ATM SVC : 0
Send Code : No Number of ATM Sig VC : 0
DS0 inuse Bitmap : 0x0 Number of FR ports : 0
Number of FR connections : 0
Number of IMA Links : 0

Bringing Up and Configuring TUG-3s

When you configure the payload for an SDH AU-4/STM-1 path, three TUG-3s are created. All three of these TUG-3s carry the same payload you assigned to the AU-4/STM-1 path, unless you assigned a VT-structured payload to the AU-4/STM-1 path. In the case of VT-structured paths, the three TUG-3s have unspecified payloads. you can assign any payload to the TUG-3s, and each TUG-3 can carry a different payload.


Note You can not configure/modify the payload for paths other than VT-structure paths.


Use the following procedure to assign a payload to a TUG-3.


Step 1 Establish a configuration session using a user name with GROUP1_GP privileges or higher.

Step 2 Enter the cc command to change to the card you want to configure.

Step 3 Enter the dsppaths -all command to ensure the SDH path is not already channelized. The Path column will report the single path number 1.1.0, and the Path Width column will report 3, as in the following example.

M8850_NY.13.MPSM155[FR].a > dsppaths -all

Path Path Admin Path Path Alarm Oper

Step 4 Bring up the path with the uppath -sts <path num> command as shown in the following example.

M8850_NY.13.MPSM155[FR].a > uppath -sts 1.1.0

Step 5 Enter the cnfpath -sts 1.1.0 -payload 9 command to set the payload type for the path to be VT-structured, and to channelize the AU-4/STM-1 path into three TUG-3s, as shown in the following example:

8850_NY.13.MPSM155[FR].a > cnfpath -sts 1.1.0 -payload 9

Step 6 Enter the dsptug3s command to display all TUG-3s. you created in Step 4.

M8850_NY.13.MPSM155[FR].a > dsptug3s

Tug3Id payload
---------- -----------
1.1.0: 1 unspecified
1.1.0: 2 unspecified
1.1.0: 3 unspecified

Step 7 Enter the cnftug3 <Path Number:Tug3> -payload <tug3Payload> command to configure the payload for the specified TUG-3. The cnftug3 command parameters are described in Table 2-17.

Table 2-17 cnftug3 Command Parameters

5 = tu3e3. Select this parameter to create one E3 and one TU (VT) path within the specified TUG-3.


In the following example, the user configures a TU-3/DS3 payload on TUG-3 1.1.0:1.

M8850_NY.13.MPSM155[FR].a > cnftug3 1.1.0:1 -payload 4

Step 8 To display the status of a TUG-3 you have brought up and configured, enter the dsptug3cnf <Path Number:Tug3> command as shown in the following example. Replace <Path Number:Tug3> with the path number for the TUG-3, in the format bay.line.AU4:Tug3.

M8850_NY.13.MPSM155[FR].a > dsptug3cnf 1.1.0:1
Path Number : 1.1.0
Tug3 Id : 1 Payload Type : tu3ds3

M8850_NY.13.MPSM155[FR].a >

Step 9 Enter the dsppaths -all command to view all configurable sub-paths that were created in Step 5.

Step 10 Use the appropriate procedure to bring up and configure TUG-3 sub-paths:

To bring up and configure VT paths, see the "Bringing Up and Configuring TUG-3s" procedure earlier in this chapter.

To bring up and configure DS1 paths, see the "Bringing Up and Configuring DS1(T1) and E1 Paths" procedure earlier in this chapter.

To bring up, further channelize, and configure DS3 paths, see the "Bringing Up and Configuring a DS3 (T3) Path" procedure earlier in this chapter.


Setting the Service Context on MPSM-T3E3-155 and MPSM-16-T1E1 Cards

The MPSM-T3E3-155 and MPSM-16-T1E1 cards support both ATM and Frame Relay services simultaneously. In order to support these individual services, each card maintains the following service contexts:

ATM — provides ATM service management commands

Frame Relay — provides Frame Relay service management commands.

This service context information is stored as a part of the card configuration for that logical slot on the hard disk on the controller card. You can switch to either service (ATM of Frame Relay) at any time by entering the setctx command. You need to switch to the appropriate service each time you want to manage Frame Relay or ATM services.

You can change the default service context of the logical slot with the cnfclictx command. The default service context is the context that will be used when you first cc to the card. For example, if you are only using ATM on a card, it would be best to set the default context to ATM. However, if half of the ports are configured for ATM and the other half are configured for Frame Relay, the default context may not matter to you, and you can set it any way you want to.

Before you can provision Frame Relay or ATM services on the card, you must ensure that it is in the proper service context. Before you can provision ATM services as described in Chapter 3, "Provisioning ATM Services on MPSM-T3E3-155 and MPSM-16-T1E1," the card must be in the ATM service context. Before you can provision Frame Relay services as described in Chapter 4, "Provisioning Frame Relay Services on MPSM-T3E3-155 and MPSM-16-T1E1," the card must be in the Frame Relay service context.

Setting the Default Service Context

The default service context is the service that is available when you first cc to the card. For example, if the card's default service context is set to Frame Relay, then that card will always be in the Frame Relay service context when you first cc to the card. On other words, only the Frame Relay CLI will be available until you change to the ATM CLI context with the setctx atm command, or until you change the default service context to ATM with the cnfclictx atm command. Use the following procedure to set the default service context.


Step 1 Enter the dspclictx command to display the default CLI service context that is currently configured in the database for the logical slot. In the following example, the default service context is FR (Frame Relay).

M8850_NY.13.MPSM155[FR].a > dspclictx
This card's default service context is: FR

Step 2 Enter the cnfclictx <service context> command to change the default service context for the current card. Replace <service context> with atm to change the default service context to be ATM, or replace it with fr to change the default service context to be Frame Relay. In the following example, the user changes the service context to be ATM.


M8850_NY.13.MPSM155[FR].a > cnfclictx atm

Step 3 Enter the dspclictx command to verify that the default service context has been changed to be ATM.


M8850_NY.13.MPSM155[FR].a > dspclictx

M8850_NY.13.MPSM155[FR].a > This card's default service context is: ATM

Note that the command prompt does not change to reflect the default service context that was set with the cnfclictx command. In the example, the command prompt shows [FR] (Frame Relay), even though the user just set the default CLI context to be ATM. This is because the current CLI context for the card in slot 13 has been set to Frame Relay with the setctx command. The switch prompt will show [FR] (Frame Relay) until the user changes the CLI context to be ATM with the setctx command, or until the user logs out of the current session.


Switching from one CLI Context to Another

The current CLI context for the MPSM-T3E3-155 or MPSM-16-T1E1 is reflected in the switch prompt. If the current CLI context for the card is ATM, the switch prompt includes [ATM] with the card name, as shown in the following example:

M8830_CH.12.MPSM155[ATM].a >

If the current CLI context for the card is Frame Relay, the switch prompt includes [FR] with the card name, as shown in the following example:

M8830_CH.12.MPSM155[FR].a >

To switch from one CLI context to another, enter the setctx <service context> command. Replace <service context> with atm to set the current CLI context to be ATM, or replace it with fr to set the current CLI context to be Frame Relay.

In the following example, the user sets the CLI context to be Frame Relay.

M8850_NY.13.MPSM155[ATM].a > setctx fr

M8830_CH.12.MPSM155[FR].a >

Note that the switch prompt reflects the CLI context change to Frame Relay. Only the commands specific to the Frame Relay service context are visible and available in that CLI session until the CLI context is changed to ATM with the setctx atm command, or until the user ends the current session (if the default CLI context was set to ATM with the cnfclictx atm command.)
