Setting Up an ATM Connection

To set up an ATM connection, perform the following steps:

Step 1   Activate a line with the upln command. Activation makes the line available for you to configure it and causes statistics gathering to begin. Subsequently, you can begin to add connections with addcon. You can verify activation with the dsplns command.

Step 2   Activate the ATM port with the upport X.X command, where X.X is the shelf slot and port (1-4) of the ATM card set.

Step 3   Use the cnfport command to establish the characteristics for the ATM port.

Step 4   If a suitable class is already configured, note its number and use this class when adding the ATM connection with the addcon command. (The dspcls command displays the parameters for each connection class. The cnfcls command allows an individual class to be modified.)

Step 5   Use the vt command to log in to the node at the remote end of the proposed ATM connection.

Step 6   At the remote node, use the upport and cnfport as listed in steps 1 and 2 to activate and configure the remote port.

Step 7   Use the addcon command at one end of the connection to activate the ATM connection.

Managing Bandwidth

The following commands help you manage bandwidth to achieve better traffic patterns.

cnfpref

The cnfpref command lets you specify preferred routing for intra-domain connections to help balance the load on the trunks.

dsprts, prtrts

The dsprts and prtrts commands display the routing information for existing connections.

dncon, upcon

The dncon command temporarily downs commands. The upcon command ups a downed command. Downing connections releases bandwidth for other services. Often, it is possible to down some voice connections to provide more bandwidth for data, frame relay, or ATM traffic.

Other Commands

The following commands may be useful for establishing connections.

· delcon

Deletes connections.

· dnln

Downs (deactivates) a line. A downed line carries no statistics or signalling. Before you can down a line, all connections that use the line must be deleted (see delcon).

· dspcons

Displays the connections on a specified ATM line.

· dsplns

displays the line configuration and alarm status for the node.

· dsplnutl

displays the line utilization for an ATM line.

addcon

Establish an ATM connection for a channel between the current node and one or more nodes in the network. You can specify a port on either an ASI or a BXM card set. For a description of the addcon command as it applies to frame relay connections, voice connections, or data connections, refer to the chapter that applies to the specific connection type. When used with the syntax in this chapter, addcon adds any one of the following types of ATM connections:

This description has the following explanations in the form of figures and tables

For detailed descriptions of the connection types, traffic classes, policing, and ATM-related topics, refer to the Cisco WAN Switching BPX Reference, the Cisco WAN Switching System Overview, and the ATM Forum specifications.

The node on which addcon executes is the "owner" of the connection. Connection ownership is important because automatic rerouting and preferred routing information is entered on the node that owns the connection. See the cnfpref and cnfcos descriptions for details on automatic rerouting.

The parameter prompts depend on the connection type. The figures on this and the following pages are flow diagrams showing the sequence of possible parameter prompts according to the connection type. The flow diagrams begin at the point after you have entered the remote node name and VPI and VCI (which are common parameters). The subsequent tables define the parameters and list the defaults and ranges for each parameter.

A form of notation appears for some parameters that may need explanation. The notation is either (0), (1), or (0+1). This refers to the state of the Cell Loss Priority (CLP) bit. The usage of the CLP bit is in the traffic policing schemes. (0+1) means cells with CLP=0 or 1. (0) means cells with CLP=0. (1) means cells with CLP=1. The CLP bit is used in different contexts. For example, CDVT (0+1) refers to Cell Delay Variation Tolerance (CDVT) for cells with CLP=0 or 1.

Before a connection is added, the proposed connection appears on the screen with a prompt for confirmation. After addcon executes, the system software automatically routes the connection.

Table 10-3 contains descriptions of the ATM parameters that appear on screen. Table 10-4 gives the defaults, ranges (or values), and applicable connection type (marked with an X) for each parameter. Table 10-5 gives a shorthand definition of each type of traffic policing. In Table 10-5, note that VBR.1, VBR.2, VBR.3, CBR.1, UBR.1, and UBR.2 are ATM Forum standards for traffic policing. The columns in Table 10-5 indicate the actions involved with each policing type. For descriptions of the traffic types, connection types, and traffic policing, refer to the Cisco BPX 8600 Series Reference and the Cisco WAN Switching System Overview. The preceding flow diagrams help clarify the information in the forthcoming tables. The remaining parts of this description contain attributes and screen examples.

Note If the description states the parameter is transmit/receive, the system is prompting for two values: one is for the transmit direction, the other for the receive direction. Also, not all parameters apply to OC3/STM1 or OC12/STM4, as the text indicates.

Table 10-3: addcon-Parameters
Parameter/Prompt Description

local channel

Specifies the local slot, port, virtual path identifier (vpi), and virtual connection identifier (vci) for the connection. The format is slot.port.vpi.vci.

The vpi range for a UNI connection is 0-255. The vpi range for an NNI connection is 0-1023

The range for a vci is 1-4095. The vci can be an asterisk (*) to indicate the connection is a virtual path connection (so the vci has no meaning within the network).

remote node name

Specifies the name of the node at the other (or remote) end of the connection.

remote channel

Specifies the remote node's slot, port, vpi, and vci for this connection. The format is slot.port.vpi.vci. The vpi and vci ranges are:

The vpi range for a UNI connection is 0-255. The vpi range for an NNI connection is 0-1023

The range for a vci is 1-4095. The vci can be an asterisk (*) to indicate the connection is a virtual path (the vci does not provide a distinction within the network).

connection class

Specifies one of the following connection types: VBR, UBR, CBR, ATFST, ATFR, ABRSTD, or ABRFST. The subsequent displayed parameters depend on the connection type you choose. To see the parameters associated with each connection type, refer to the appropriate flow diagrams (Figure 10-1 through Figure 10-7). For a definition of each class, refer to the Cisco WAN Switching System Overview.

The option for choosing a class number is also available. The class is a template for a connection type. The class serves as an alternative to specifying each parameter for a connection type. To specify a connection class, enter a digit in the range 1-10. To see the parameter values for a class, use the dspcls commands. To customize any class template, use cnfcls.

PCR

Peak Cell Rate: the cell rate that the source cannot exceed.

%Util

Specifies the percentage of bandwidth utilization.

MCR

Minimum Cell Rate: the committed, minimum cell rate for a connection in a network.

CDVT

Cell Delay Variation Tolerance: controls time scale over which the PCR is policed.

FBTC (AAL5 Frame Base Traffic Control)

Enables the possibility of discarding a whole frame rather than a single, non-compliant cell. FBTC used to set the Early Packet Discard bit at every node along a connection.

VSVD

Virtual Source Virtual Destination.

Flow Control External Segments

Enables Cisco WAN switches to perform flow control on external segments (on the CPE, for example) in addition to the Cisco WAN switch segments.

SCR

Sustainable Cell Rate: the long-term limit on the rate that a connection can sustain.

MBS

Maximum Burst Size: the maximum number of cells that can burst at the PCR and still be compliant. MBS is used to determine the Burst Tolerance (BT), which controls the time period over which the SCR is policed.

Policing

(see Table 10-5, "Traffic Policing Definitions").

VC QDepth

The depth of the queue VC QDepth.

CLP Hi

Cell Loss Priority Hi threshold (% of VC QDepth). When the high threshold is exceeded, the node discards cells with CLP=1 until the number of cells in the queue drops below the level specified by CLP Lo/EPD.

CLP Lo/EPD

Cell Loss Priority Low threshold (% of VC QDepth)/Early Packet Discard. When the number of cells in the queue drops below the level specified by CLP Lo/EPD, the node stops discarding cells with CLP=1.

If the card is a BXM and AAL5 FBTC=yes, the percent of VC QMax equals the value of EPD. Frame-based Traffic Control (FBTC) is FGCRA for AAL5.

For an ASI card, the percent of VC QMax is CLP Lo regardless of the FBTC setting.

EFCI

Explicit Forward Congestion Indication threshold (% of VC QDepth).

ICR

Initial Cell Rate: the rate at which a source initially transmits after an idle period.

IBR

Initial Burst Size: the maximum burst size a source can initially transmit after an idle period. IBR applies to only BXM cards.

ADTF (ATM Forum TM 4.0 term)

The Allowed-Cell-Rate Decrease Factor.

Time permitted between sending RM-cells before the rate is decreased to ICR. (In previous software releases, ADTF was ICR TO—Initial Cell Rate Time Out.)

Trm (ATM Forum TM 4.0 term)

An upper bound on the time between forward RM-cells for an active source: an RM cell must be sent at least every Trm milliseconds. (In previous software releases, Trm was Min. Adjust.)

RIF (ATM Forum TM 4.0 term)

Rate Increase Factor: controls the amount by which the cell transmission rate may increase upon receipt of an RM cell. (In previous software releases, RIF was Rate Up.)

RDF (ATM Forum TM 4.0 term)

Rate Decrease Factor: controls the amount decrease in cell transmission rate when an RM cell arrives. (In previous software releases, RDF was Rate Down.)

Nrm (ATM Forum TM 4.0 term)

Nrm.

Maximum number of cells a source may send for each forward RM cell: an RM cell must be sent for every Nrm-1 data cells.

FRTT (ATM Forum TM 4.0 term)

Fixed Round Trip Time: the sum of the fixed and propagation delays from the source to a destination and back.

TBE (ATM Forum TM 4.0 term)

Transient Buffer Exposure

The negotiated number of cells that the network would like to limit the source to sending during start-up periods, before the first RM-cell returns.

PCR

Peak cell rate: the cell rate which the source may never exceed.

addcongrp

Sets up a group to which ATM connections between the local node and a remote node are added. The connection group is a routing entity that is initially empty and to which individual connections (virtual circuits) are added using the grpcon command. Connections added to a group must be of the internode, non-bundled, ATM type. The connections must have the same routing parameters. These parameters include connection owner, class of service (COS), connection state, route restrictions, and ForeSight enable status.

Connection grouping permits an IPX or IGX node to have up to 1000 connections and a BPX node to have up to 5000 connections. A connection group may have up to 16 connections.

Parameter

Description

optional parameters

Individual parameters are specific to the class type (CBR, VBR, UBR, ABR, ATFR). Use the dspcls command to see the parameters in a each of the classes.

cnfcon

Configures the ATM bandwidth parameters for a specified connection. The initial cell rate (ICR) normally is set to the port speed. It may be lower if other constraints exist on the data generation rate. If ICR is too low, cells are dropped. If it is too high, bandwidth may be wasted unless ForeSight is used. Statistical reports are the best source of information for deciding what to adjust.

If the connection type includes ForeSight (abr enabled), the results of the last test round trip delay command (tstdelay) appear. Note that this is not the current RTD but the result of the last test that ran. Connection priority—high or low—is displayed for standard frame relay connections and ForeSight connections. Several checks are done on the parameters that specify bandwidth to assist users in efficient use of network bandwidth. The following messages describe the performance evaluation.

· Error

Min cannot exceed peak.

· Warning

Min exceeds this port's speed.

· Warning

Sum of mins exceeds port's speed.

· Warning

Peak exceeds this port's speed.

Warning messages are informational only, so the related operation continues. If an error message appears, the operation does not continue.

Parameter Description

slot.port

Specifies the ASI or BXM card slot and port number.

nni/uni

Specifies whether the cell header format is NNI or UNI.

axis

Specifies AXIS queue depth for each slot.

metro data cell header

Specifies whether the metro data cell header type is used.

shift h | n

Specifies whether a one-byte shift on the HCF field of the cell header occurs. The choice of H (shift) or N (no shift) depends on whether the ATM cloud includes non-Cisco WAN switches and whether virtual trunking is in operation:

Select H (the default) if the cloud includes non-Cisco WAN switches or if only a physical trunk is configured for the ASI port.

Select N if virtual trunks are configured and the ATM cloud consists of Cisco WAN switches only.

protocol

Specifies the use of either an LMI protocol, an ILMI protocol, or no specified protocol.

%util

Enables/disables percent utilization. This parameter supports ATM VBR/ABR fairness for ASI or BXM-terminated connections. It applies to only VBR and ABR connections. To change the %util status of a port, no connections can be currently terminating on the port. Therefore, if connections terminate on the port, you must delete them before you execute cnfport then re-add the connections afterwards.

When %util is disabled, the port queue bandwidth is calculated using the sum of the MCRs or PCRs for the connections terminating on the port. The port queue bandwidths with %util feature disabled are:

  • For ABR connections Port Queue BW = sum (MCR)

  • For VBR connections Port Queue BW = sum (PCR)

  • For CBR connections Port Queue BW = sum (PCR)

When the %util feature is enabled, the port queue bandwidth is calculated for ABR and VBR connections as follows: for ABR connections, the port queue bandwidth is the sum of a percentage of the MCRs for the connections terminating on the port; for VBR connections, the port queue bandwidth is the sum of a percentage of the PCRs for connections terminating on the port. The %util feature does not apply to CBR connections, as the following summary shows. The port queue bandwidth with the %util feature enabled is:

  • For ABR connections Port Queue BW = sum (MCR * %util)

  • For VBR connections Port Queue BW = sum (PCR * %util)

  • For CBR connections Port Queue BW = sum (PCR)

SVC Channels

The number of SVC channels for the card or port. The interface type determines whether the specification is per card or per port. The default is 0. The ranges are:

T3: 0-1000 channels per card
E3: 0-1000 channels per card
OC3: 0-1000 channels per port

SVC VPI Min

The VPI minimum that creates the lower boundary of the SVC range. The range is 0-4095. The default is 0. Your entry must be less than the SVC VPI Max.

SVC VPI Max

The VPI maximum that creates the upper boundary of the SVC range. The range is 0-4095. The default is 0. Your entry must be greater than the SVC VPI Min.

SVC Bandwidth

The bandwidth reserved for the SVC connections. The default is 0 cps. The ranges depend on the interface and are as follows:

T3: 0-96000 cps
E3: 0-80000 cps
OC3: 0-353208 cps

cnfportq

Configures queue parameters on an ASI card or a BXM card in (UNI) port mode. To keep the current value for a parameter, press Return without typing a value.

Note The ASI has only egress queues, so the parameters are egress only. BXM queue parameters are egress and ingress.

dspportstats

Displays a summary of port statistics for the ATM port specified. These include the cell count in the transmit and receive directions, and error counts associated with the port. The display indicates the date and time that the statistics were cleared and the statistics collection time since the last clearance. Cells transmitted indicates the amount of data transmitted out the port to the user device. Cells received indicates the amount of data received from the user device at the port. Corrupted statistics result from channel/port loopbacks or port tests. A yes in this field indicates that such loopback or port test have occurred since the statistics were last cleared.

Parameter Description

interval

Specifies the refresh interval time for data. It can be specified between 1 and 60 seconds. The default interval is 1 seconds.

grpcon

Adds a connection to a group. Adding a connection to a group has two prerequisites:

No command exists to delete an individual connection from a group. Instead, the connection must be deleted (using delcon) then added again. The grpcon command can be used to add either a single connection or multiple connections. Using the optional channel ... channel parameter format, a range of 1 - 16 connections can be added to the group in one command. All connections in the group must be of the inter-node, non-bundled ATM type. They must also have the same endpoints, routing characteristics, and ForeSight enable status.

The first connection added to a group determines the routing characteristics of the entire group. All subsequent connections must match the first connection's characteristics of ownership, COS, routing state, routing restrictions, and ForeSight. Attempting to add a dissimilar connection results in an error message "mismatched connection/group" characteristic. For example, the ownership of both the connection group and the connection itself must be either local or remote. Non-connection parameters, such as fail state, loop state, and configuration, can be specified for an individual connection in the group after the connection has been added to the group.
