Setting Up Lines

A circuit line is the physical line that carries data, voice, Frame Relay, or ATM traffic between an IGX or BPX node and customer premises equipment (CPE). Each piece of customer premises equipment is attached to a node through a circuit line. After a card has been "upped" with the upcd command, a circuit line on that card can be "upped" and configured.

This chapter:

Describes input circuit line formats
Summarizes circuit line card combinations
Explains how to set up lines
Describes each command

Note Line commands are the same as circuit line commands. However, the cnfcln command is no longer used; use cnfln instead. The switch software prompts for the parameters appropriate for the card type it detects.

Table 5-1 shows input line formats. Table 5-2 shows the permissible card combinations for CPE-to-IGX lines.

Setting Up a Circuit Line

Frame Relay, data, and voice connections require an active line. Use the commands in the following steps to establish a line. The card must be in either the active or standby state before you enter these commands.

Step 1 Use the upport command to activate ports at both ends of the line before running upln.

Step 2 Use upln to activate a circuit line in a slot that contains the appropriate circuit line card set.

Step 3 Use cnfln to configure the circuit line.

The upln and cnfln commands establish the general parameters for the line but do not establish specific Frame Relay, data, or voice parameters. Refer to applicable chapters for details on a particular service. For example, Data Connections describes specific commands for data connections, and Frame Relay Connections describes specific commands for Frame Relay connections.

Setting Up an IMA Line

Inverse Multiplexing over ATM (IMA) allows you to group physical T1 or E1 lines to form a logical line, also known as an IMA line. By bundling smaller lines together to form an IMA line, you enlarge the traffic bandwidth on your network without upgrading to a higher speed service, such as T3/E3. Therefore, you're

the access lines you already have instead of replacing them. The IMA line feature is compliant with ATM Forum Standard version 1.0, allowing UXM IMA trunks to interoperate with other vendor equipment.

IMA line characteristics are as follows:

Supports up to eight T1/E1 lines.
Connects to any CPE that is ATM Forum IMA Standard Version 1.0 compliant.
An IMA line and a non-IMA line can coexist in the same card.
Physical links can be added or deleted while the IMA group is active. Exceptions are:

A physical line cannot be deleted from a group if the resulting numbers of physical lines in the IMA group is less than the minimum retained links specified.
The primary link (the first physical line in the IMA group) can not be deleted dynamically.

Ability to configure the differential delay for the IMA line.
All physical ports of an IMA line use the same line configuration.
The IMA line supports Common Transmit Clock (CTC) mode; meaning, all lines in the IMA group use the same clock mode.
Full support for individual physical line alarms and statistics.
Ability to configure the minimum retained links in the IMA group; for example, if 8 T1 lines compose an IMA line, you specify how many active T1 lines in the group can fail before the IMA line fails.

To configure an IMA line:

1. Use the upln command to create an IMA group, specifying a range of ports for the IMA Line. The syntax for the command is:

: upln <slot>.<group-members>
: Where group-members are the physical lines composing an IMA group; for example:

2. Use the upport command to activate ports at both ends of the line before running upln. The upport command uses the primary link designation.

3. Use the cnfln command to configure the minimum number of retained links and the differential delay.

To modify an IMA line:

1. Use the cnfln command to add lines to or delete lines from an IMA group, using the parameter IMA Group Members. You cannot change or delete a primary link from the IMA group. Should you wish to delete the primary link, you first must use the dnport command, then deactivate the line using the dnln command.

2. Use the cnfln command to change the minimum number of retained links, and the differential delay.

3. Use the dnln command to deactivate the line. A downed line is inactive, so no traffic is passed and no statistics are generated. You must remove all connections on a line (delcon or delcongrp) before you down the line with dnln.

To view IMA line information:

1. Use the dsplog command following an upln command to confirm that the IMA line is activated and operating; for example, following the upln 10.1 command, the dsplog command shows:

Clear LN 10.1 OK
Clear LN 10.1 Activated
Clear PHYSLN 10.1 OK
Clear PHYSLN 10.1 Activated

: Following a dnln 10.1 command, the dsplog command shows:

Clear LN 10.1 Deactivated
Clear PHYSLN 10.1 Deactivated

: Following an Inverse Mux Failure for an IMA group with three lines in the group, the dsplog command shows:

Major LN 10.2(3)Inverse Mux Failure
Major PHYSLN 10.4 Inverse Mux Failure
Major PHYSLN 10.3 Inverse Mux Failure
Major PHYSLN 10.2 Inverse Mux Failure

2. Use the dsplns command to show the number of lines in the IMA group, and the alarm status for the IMA line; for example:

dsplns 3.1 
System Response: 3.1 (4) OK

: IMA line failure is indicated by the error message Inverse Mux Failure. An Inverse Mux Failure can be triggered by:

3. Use the dsplncnf command to display the IMA group members that compose the IMA line.

4. Use the dspport command to identify that the port is in an IMA Port Group and the IMA line speed. In the example below, the port group is 2.5 and the line speed is 13433 cps.

To configure and view IMA statistics:

1. Use the cnfphyslnstats command (Super User privilege) to configure parameters for collecting circuit line statistics, including IMA-specific statistics. Refer to the Cisco WAN Switching SuperUser Command Reference for information about the cnfphyslnstats command.

2. Use the dspphyslnstatcnf command (Super User privilege) to view the parameters configured for collecting circuit line statistics, including IMA-specific statistics. Refer to the Cisco WAN Switching SuperUser Command Reference for information about the dspphyslnstats being collected.

3. Use the dspphyslnstathist command (Super User privilege) to display the actual statistics information for one type of physical line statistic on an active IMA line on a UXM card. Refer to the Cisco WAN Switching SuperUser Command Reference for information about the dspphyslnstathist.

Calculating Transmit and Receive Rates on IMA Lines

The port rate of an IMA line is the sum of all physical lines less the IMA protocol overhead. The overhead is calculated as:

1-4 lines = 1 DSO
5-8 lines = 2 DSO

When an IMA group is reconfigured, the IMA line bandwidth is readjusted automatically because of the change in the total number of links.

Please refer to Table 5-3 for composite port speeds.

cnfcassw

Configures a UVM to convert channel associated signaling (CAS) and dual-tone multi-frequency (DTMF) tones to common channel signaling (CCS) call control messages. This conversion is necessary for voice networks in which a Voice Network Switch (VNS) uses SVCs to route calls from a CAS-based PBX through a WAN. Model B or later firmware on the UVM is necessary.

Before you can execute cnfcassw, note the following:

The line to which you apply cnfcassw must be up.

If any connections exist on the line, you cannot change the cnfcassw parameters. However, you can execute the command to see the current parameters in the cnfcassw display.

You cannot configure a line for both CAS-switching and pass-through.

With CAS-switching on a UVM that has Y-cable redundancy, the call state of each connection is lost in the event of a switch-over.

Syntax

cnfcassw <line> <mode> <CCS type> <CAS type> <conn type> <country code>
<interdigit timeout> <tone level> <DTMF duration> <idle pattern> <parameters 6-18>

Note For the initial implementation of CAS switching, you should specify only port 1 for the line parameter (where line has the format slot.port) and select "PBX-end" for mode.

cnfln

Configures a line to be compatible with the device to which it connects. The cnfln command applies to voice, data, Frame Relay, and ATM, and IMA lines. See Table 5-3 for a list of the front and matching back cards. Because of the variety of line types and characteristics, the parameters section of this description has three tables to describe the parameters. The system automatically presents the correct options on the command line for each line type. If a parameter is not applicable to a card type, the system displays the parameter in half-tone or the value field of that parameter with dashed lines. Table 5-5 describes the parameters for voice, data, and Frame Relay parameters. Table 5-6 describes the parameters for the ATM Line Module (ALM/A). Table 5-7 describes the parameters for the ASI line card (BPX node). Table 5-8 describes the ATM parameters for the UXM card (IGX node). describes the IMA parameters for the UXM card (IGX node).

For an ALM/A, the cnfln command lets you configure the receive rate and header type and enable payload scrambling. For more details on the features and configurable parameters of the ALM/A, refer to the Cisco IGX 8400 Series Reference and the Cisco IGX 8400 Series Installation manuals. Note that, although the cnfln display shows the transmit rate, you cannot configure it because the ALM/A transmit rate is always the maximum line rate.

For an IMA line, you can add or delete links in an IMA group, or specify the number of retained links for an IMA configuration. By default, the number of retained links is the same as the number of lines grouped together when the IMA group is created; for example:

: upln 3.1-4

Results in 4 lines in an IMA group with 4 retained links. If one link fails, the IMA line fails. Using the cnfln command, you can change the parameter "Retained Links" to a lesser number, for example, 3. Therefore, if one of the lines failed, the IMA line could remain active.

For more information about commands related to IMA lines, refer to List of Commands.

Note The cnfln command is the same as cnfcln.

Turn on SVC-Caching (Y):

This release has added a prompt to configure a UVM line for SVC Caching. It is also supported on CVM lines on the IPX. The SVC Caching feature speeds up call setup for most VNS controlled calls by avoiding some of the call setup/tear-down operations when a call originates or terminates.

Refer to the VNS Installation and Configuration Manual for more information on SVC Caching.

cnfrsrc

Use the cnfrsrc command to partition resources (ports and trunks) for Automatic Routing Management PVCs, VSI-MPLS (Multiprotocol Label Switching), or PNNI SVCs. (If you want to configure resources for a VSI-MPLS controller or PNNI SVCs, refer to cnfrsrc in the "VSI Commands" chapter for more information specific to configuring VSI options.)

Note Note that VSI-MPLS is supported in this release. Up to two controllers of the same type can be attached to a node and assigned the same partition to provide controller redundancy on that partition. A different set of controllers can be attached to the node and be assigned a different partition to provide controller redundancy on this second partition.

You can configure a virtual trunk to be dedicated to VSI or to Automatic Routing Management. You cannot configure a virtual trunk for both VSI and Automatic Routing Management.

This command was introduced in Release 9.1 to support physical trunks. It has been extended to support virtual trunks. After VSI has been enabled, the virtual trunk becomes a "dedicated" VSI virtual trunk. Note that if the trunk has already been added or if the VPI value has not been configured, you will not be able to configure the VPI value. (Switch software will block you from doing so.)

Configurable resources (using cnfrsrc) are:

Template number— only relevant when configuring VSI options
Maximum PVC LCNs
Maximum PVC Bandwidth
Configure Partition (Y/N)—Enter "n" for No to configure Automatic Routing Management PVCs. Enter "y" for yes to configure VSI options.
Partition ID
Enable Partition (Enable/Disable)
Minimum VSI LCNs
Maximum VSI LCNs
Start VSI VPI - Warning message will tell you to use the cnftrk command
End VSI VPI - Warning message will tell you that the end vsi vpi is equal to the start vsi vpi for virtual trunks
Minimum VSI Bandwidth
Maximum VSI Bandwidth

The resources that you can currently configure are the number of connection IDs (conids) and the trunk bandwidth. You use the cnfrsrc command to configure the cell rate and number of connections on a BXM card only. (You cannot use the cnfrsrc command on the IGX.)

You configure all port and trunk attributes with cnftrk, cnftrkparm, or cnfrsrc. Note that when you change a physical port attribute, you will be notified that all the logical (physical and virtual) trunks on the port are affected.

Note Note that when using cnfrsrc to configure partition resources for Automatic Routing Management PVCs, and you are prompted whether you want to configure VSI options, enter "n" for No. You will not be prompted to enter any VSI options.

Table 5-11: cnfrsrc—Parameters

Parameter	Description
slot.port	Specifies the BXM card slot and port number.
Maximum PVC LCNs	The maximum number of LCNs allocated for Automatic Routing Management PVCs for this port. The range is 1 to 256; 256 is the default. For trunks, there are additional LCNs allocated for Automatic Routing Management that are not configurable. You can use the dspcd <slot> command to display the maximum number of LCNs you can configure using the cnfrsrc command for the given port. For trunks, configurable LCNs represent the LCNs remaining after the BCC has subtracted the networking LCNs needed. A trunk has 270 networking LCNs, or channels. For a port card, a larger number is shown, as compared with a trunk card. This is because a trunk uses 270 networking LCNs, as compared with a port card, which uses no networking LCNs. Setting this field to "0" would disable Automatic Routing Management PVCs on the specified port. Note that you must specify a value greater than 0 for the Maximum PVC LCNs, Maximum PVC Bandwidth, and Maximum VSI LCNs parameters. Otherwise, you will not be able to create any Automatic Routing Management PVC connections on a BXM card. Also, if these parameters do not have values greater than 0, you will be unable to change the connection channel amount when you configure the BXM trunk using cnftrk.
Maximum PVC Bandwidth	Specifies the maximum bandwidth of the port allocated for Automatic Routing Management use. The range is 0 to 352207; 0 is the default. You can configure the Maximum PVC Bandwidth value for ports, but not for trunks. Note that you must specify a value greater than 0 for the Maximum PVC LCNs, Maximum PVC Bandwidth, and Maximum VSI LCNs parameter. Otherwise, you will not be able to create any Automatic Routing Management PVCs on the BXM card.
Configure Partition	Answer yes or no to begin configuring resources for the partition. If you enter "n" for No, you will not be prompted to configure any VSI options. If you are configuring Automatic Routing Management PVCs, enter "n" for No. If you want to configure VSI options, enter "y" for yes, and you will be prompted to enter the rest of the cnfrsrc parameters, which are related to configuring VSI (such as a VSI MPLS controller or a PNNI controller). Refer to the cnfrsrc command in "VSI Commands" chapter for more information on VSI-related options.
Partition ID	Specifies the ID number of the partition; 1 is the default. Always use 1 in Release 9.1. In this release, you can use 2. (The range of 0 to 255.)
Enable Partition	Answer yes or no to enable your configured partition.
Minimum VSI LCNs	The minimum number of LCNs guaranteed for this partition. The range is 1 to 256; 0 is the default. The VSI controller guarantees at least this many connection endpoints in the partition, provided there are sufficient free LCNs in the common pool to satisfy the request at the time the partition is added. When a new partition is added or the value is increased, it may be that existing connections have depleted the common pool so that there are not enough free LCNs to satisfy the request. The BXM gives priority to the request when LCNs are freed. The net effect is that the partition may not receive all the guaranteed LCNs (min LCNs) until other LCNs are returned to the common pool. You can increase this value dynamically when there are enough unallocated LCNs in the port group to satisfy the increase. You may not decrease the value dynamically. All partitions in the same port group must be deleted first and reconfigured in order to reduce this value. To avoid this deficit condition, which could occur with maximum LCN usage by a partition or partitions, it is recommended that all partitions be configured ahead of time before adding connections. Also, it is recommended that all partitions be configured before adding a VSI controller using the addshelf command.
Maximum VSI LCNs	The total number of LCNs the partition is allowed for setting up connections. The min LCNs is included in this calculation. If max LCNs equals min LCNs, then the max LCNs are guaranteed for this partition. Otherwise, (max - min) LCNs are allocated from the common pool on a FIFO basis. If the common pool is exhausted, new connection setup requests will be rejected for the partition, even though the maximum LCNs has not been reached. You may increase this value dynamically when there are enough unallocated LCNs in the port group to satisfy the increase. You may not decrease the value dynamically. All partitions in the same port group must be deleted first and reconfigured in order to reduce this value. Different types of BXM cards support different maximum values. If you enter a value greater than the allowed maximum, a message is displayed with the allowable maximum value. Note that you must specify a value greater than 0 for the Maximum VSI LCNs, Maximum PVC Channels, and Maximum PVC Bandwidth parameters. Otherwise, you will not be able to add any connections on a BXM card.
Start VSI VPI	By default the TSC (for example, the 7200 or 7500 series router) will use either a starting VSI VPI of 1 or 2 for tag switching, whichever is available. If both are available, a starting VSI VPI of 1 is used. The VPI range should be 2-15 on a BPX 8620 VSI. The VSI range for tag switching on the BPX 8620 is configured as a VSI partition, usually VSI partition number 1. VSI VPI 1 is reserved for Automatic Routing Management PVCs. (This restriction applies only to trunks, not to ports. For a port, you can use any VPI value.) For a port UNI, the VPI range is 1 to 255. For a port NNI, the range is 1 to 4095. For trunks that do not have Automatic Routing Management configured, the VPI ranges are the same as for ports. The VSI partition for tag switching should start at VPI 2. If VPI 2 is not to be used, you can use the tag switching VPI interface configuration on the TSC to override the defaults. For trunks with Automatic Routing Management configured, the range is 2 to 4095. Always set to 2 for trunks.
End VSI VPI	Two VPIs are sufficient for Release 9.1, although it may be advisable to reserve a larger range of VPIs for later expansion, for example, VPIs 2-15. The range is the <Start VSI VPI > value to 4095.
Minimum VSI Bandwidth	The minimum port bandwidth that can be used by this partition in cells/second. The range is 0 to <Maximum Line Rate>. For example, the OC-3 line rate is 352207; 0 is the default.
Maximum VSI Bandwidth	The maximum port bandwidth that can be used by this partition. This value is used for VSI QBins bandwidth scaling. The range is 0 to <Maximum Line Rate>. For example, the OC-3 line rate is 352207; 0 is the default.

dnln

Deactivates ("downs") a line. After dnln executes, the line no longer generates framing, and no statistics are gathered. Before you deactivate a line, use delcon to remove all connections on the line and use dnport to deactivate the port associated with the line.

The dnln command is used to deactivate an IMA line, too (IGX only). As with the other lines, you must remove all connections on the IMA line (delcon or delcongrp), then deactivate the port using the dnport command. You then can deactivate the line with dnln

For more information about IMA lines, refer to Setting Up an IMA Line.

Note The command is the same as the dncln command.

dsptsmap

Use the dsptsmap command to display the channel to timeslot mapping usage information on a UVM card on an IGX node or a CDP/CVM card on an IPX node. The dsptsmap command is for use with the SVC caching feature, which speeds up call setup for most VNS controlled calls. The SVC caching feature avoids some of the call setup/tear-down operations associated with addcon and delcon as a call originates or terminates. The SVC caching feature reduces the connect time for many switch calls over a busy network.

To use the dsptsmap command, the line must have SVC caching enabled on it. You can find out if a channel is disabled by using the dsptsmap command.

The cnfln command is used to configure the SVC caching parameter setting.

The dspcons command is used to view disabled connections provided the SVC has not been deleted.

The dsplncnf command will show the value (On/Off) of the SVC caching mode feature.

Refer to the VNS Installation and Configuration Manual for more information on SVC caching.

Enabled channels are shown on the screen underlined and in reverse video. Disabled (cached) channels are shown with the channel number underlined and in reverse video, while the timeslot is shown in normal video. Channels that have no connection are shown in normal video for both channel number and timeslot.

For example:

Channel 1 does not have a connection.
Channel 2 is an enabled connection carrying traffic.
Channel 3 is a disabled connection.

Specify the line_number parameter in slot.line format for UVM, and line format for CDP/CVM.

Use the optional update_interval parameter to control how often the screen gets updated. If you do not enter any value through the CLI, the value of the Screen Update Time parameter set using in the cnfuiparm command is used.

Description

This command uses the same syntax and prints the same information as is displayed using the dsplns command. See the dsplns command for syntax and output information.

upln

Activates (ups) a line. Use the upln command to make the line available for configuring and to start statistics gathering.

You must execute upln at both ends of the line. Executing upln at only one end of the line eventually causes an alarm. Configure the line's signal characteristics for the data you intend for the line using the cnfln command.Once both ends of the line are active, you must activate ports at both ends of the line by executing the upport command. Once completed, add connections with the addcon command.

A line consists of a cable for transmitting data and the interface circuitry for the line. The cable can be a coaxial wire, fiber optic, or a twisted pair. See Table 5-1 for information on card combinations.

The Ports and Trunks feature lets you configure multiple trunk lines and circuit line cards on a single BXM or UXM card simultaneously. In previous releases, when a single port is upped as a trunk (by using the uptrk command), all the remaining ports on that card are treated as a trunk. Similarly, when you upped a single port as a circuit line (by using the upln command), all the remaining ports on the card are treated as circuit line ports.

For example, assuming that a four-port BXM card is plugged into slot 11, you could do the following:

1. uptrk 11.1

2. upln 11.2

3. upln 11.3

4. uptrk 11.4

That is, you could up a trunk at port 1 on slot 11, up a line at port 2 of slot 11, up a line at port 3 of card slot 11, and also up a trunk at port 4 of card slot 11.

The BXM or UXM card can be a trunk card and a line (port) card at the same time. For example, a BXM slot can up port 1 as a trunk interface while upping port 2 as a line interface.

In release 9.3, you can configure an IMA line for ports as well as trunks. Use the upln command to create an IMA group. The command syntax is:

: upln <slot>.<group-member>

Where group-member specifies a range of physical lines that compose an IMA line. The first connection in the string becomes the primary link (how the IMA group is recognized in other screens), such as dspport, dspports, and cnfln.

: upln 10.1,3,6,8 adds the primary link 10.1 and the non-consecutive physical lines 10.3, 10.6, and 10.8. When you use other commands, such as dnln or cnfln, this IMA group is known by the primary link, 10.1.
: upln 10.5-7,2-3 adds the primary link 10.5 and the physical lines 10.5, 10.6, 10.7, 10.2, and 10.3. When you use other commands, such as dnln or cnfln, this IMA group is known by the primary link, 10.5.

Please refer to Setting Up an IMA Line for further information about using this feature, as well as composite port speeds.

Multilevel Channels Statistics Feature Support in Release 9.2

To support the Multilevel Channels Statistics feature, you will be prompted when you attempt to up the line with upln or up the trunk with uptrk, warning you that you must initialize the channel statistics level before the card will be activated. The following warning applies only when upping the first trunk or first line on the card.

Channel Statistic Level must be initialized prior to card activation

Note If, after upping a BXM line, you get a message telling you to use cnfrsrc to configure PVCs, make sure that when configuring resource partitions with cnfrsrc, you specify values greater than 0 for the Maximum PVC Channels, Maximum PVC Bandwidth, and Maximum VSI LCNs. Otherwise, you will be unable to create any AutoRoute PVCs on a BXM card. You also will not be able to change the Connection Channels amount with cnftrk if these parameters' values are not set to values greater than 0.

Note The upln command is the same as upcln.
