Note ATM module software release 11.3(6)WA4(9b) is the release following ATM module software release 11.3(4)WA4(8a).

New Features

The ATM module software release  11.3(6)WA4(9b) supports PVC traffic shaping on ATM dual PHY OC-12 modules (WS-X5161 and WS-X5162) and ATM dual PHY OC-3 modules (WS-X5167 and WS-X5168).

PVC Traffic Shaping Functional Overview

PVC-based ATM links allow Catalyst 5000 family switches to connect to each other through ATM interfaces over PVCs. You can configure one or more PVCs for each VLAN on every Catalyst 5000 family ATM module. Connectivity can be back-to-back or through an ATM switch cloud, using RFC 1483-compliant, bridged Logical Link Control/Subnetwork Access Protocol (LLC/SNAP) packet encapsulation.

When you create a PVC, you create a virtual channel descriptor (VCD) and attach it to the virtual path identifier (VPI) and virtual channel identifier (VCI). A VCD identifies the VPI-VCI pair for a particular packet. The ATM module requires this feature to manage packet transmission. The number chosen for the VCD is independent of the VPI-VCI pair used.

To use PVCs, you must configure PVCs in both the Catalyst 5000 family ATM module and the ATM switch cloud. PVCs remain active until the circuit is removed from either configuration.

PVCs are compatible with switched virtual connection (SVC)-based LANE, with the following restrictions:

New Command

This section contains descriptions of the new command available in ATM module software release 11.3(6)WA4(9b). The atm pvc command is used to create a PVC on the Catalyst 5000 family switch interface. Enter the no form of this command to delete the specified PVC.

atm pvc aal5snap vcd vpi vci pcr scr mbs
no atm pvc aal5snap vcd vpi vci

Syntax Description

aal5snap

Keyword used for RFC 1483 Ethernet bridged ATM adaptation layer 5/Subnetwork Access Protocol (AAL5/SNAP) packet encapsulation type.

vcd

Virtual circuit descriptor. A unique number for each Catalyst 5000 family switch that identifies which VPI/VCI to use for a particular packet. The Catalyst 5000 family switch requires this feature to manage packet transmission. The vcd is not associated with the VPI/VCI used for the ATM network cells.

vpi

ATM network VPI of this PVC, in the 0 through 255 range. The VPI is an 8-bit field in the header of the ATM cell. The VPI value is unique only on a single interface, not throughout the ATM network.

vci

ATM network VCI of this PVC, in the 0 through 4096 range. The VCI is a 16-bit field in the header of the ATM cell. The VCI value is unique only on a single interface, not throughout the ATM network.

pcr1

(Peak cell rate) Maximum rate (in kbps) at which this virtual circuit can transmit. Valid values are 0 to 622000 for the ATM dual PHY OC-12 modules (WS-X5161 and WS-X5162) and the ATM Fabric Integration module (WS-X5165); 0 to 155,000 for the ATM dual PHY OC-3 modules (WS-X5167 and WS-X5168).

scr1

(Sustainable cell rate) Average rate (in kbps) at which this virtual circuit transmits. Valid values are 0 to 622000 for the ATM dual PHY OC-12 modules (WS-X5161 and WS-X5162) and the ATM Fabric Integration module (WS-X5165); 0 to 155,000 for the ATM dual PHY OC-3 modules (WS-X5167 and WS-X5168).

mbs

(Maximum burst size) Value that relates to the maximum number of ATM cells the virtual circuit (VC) can transmit to the network at the peak rate of the PVC. Valid values are 0 and 2 to 255.

1The minimum pcr or scr rate for is 64 kbps. If you specify a pcr or scr greater than 0 and less than 64 kbps, the rate specified to the SAR is 64 kbps.
Default

If you omit the pcr argument, the PVC defaults to the highest bandwidth rate queue available (622,000 kbps). By default, the VC is configured to run as fast as possible.

Command Type

Cisco IOS ATM command.

Command Mode

Interface configuration.

Usage Guidelines

The atm pvc command on the ATM dual PHY OC-12 modules (WS-X5161 and WS-X5162), the ATM dual PHY OC-3 modules (WS-X5167 and WS-X5168), and the ATM Fabric Integration module (WS-X5165) supports RFC 1483 Ethernet bridged AAL5/SNAP encapsulation only.

Traffic shaping supports multiple traffic classes:

When configuring a PVC, if you enter a zero value for PCR and SCR (or do not specify any value), the channel is opened with a service type of UBR (with a maximum of line-rate).
While configuring a PVC, if you enter a zero value for SCR and non-zero PCR, the channel is opened with a service type of CBR at 1/PCR.
While configuring a PVC, if you enter non-zero values for PCR and SCR, the channel is opened with a service type of VBR.

The atm pvc command creates a PVC and attaches it to the specified VPI and VCI. The vpi and vci values cannot both be specified as 0. For example, if vpi is 0, then vci cannot be 0, and conversely, if vci is 0, then vpi cannot be 0.

The pcr, scr, and mbs arguments are only supported on the ATM dual PHY OC-12 modules (WS-X5161 and WS-X5162), the ATM dual PHY OC-3 modules (WS-X5167 and WS-X5168), and the ATM Fabric Integration module (WS-X5165).

Maximum pcr values are 0 to 622,000 for the ATM dual PHY OC-12 modules (WS-X5161 and WS-X5162) and the ATM Fabric Integration module (WS-X5165); 0 to 155,000 for the ATM dual PHY OC-3 modules (WS-X5167 and WS-X5168).

The minimum pcr or scr is 64 kbps. If you specify a pcr or scr greater than 0 and less than 64 kbps, the rate specified to the SAR is 64 kbps.

Differences Between Software Releases 11.3(6)WA4(9b) and 11.3(4)WA4(8a)

This section describes software differences between Catalyst 5000 family ATM module software release 11.3(6)WA4(9b) and 11.3(4)WA4(8a).

Catalyst 5000 family ATM module software release 11.3(6)WA4(9b), LE-ARP reverifications are performed by checking the EARL table for the entry. If the EARL entry exists, this indicates that traffic has come from that address within the last five minutes. If the EARL entry still points to the data direct VC that is believed to be correct, it is good for another five minutes. This problem is resolved in ATM module software release 11.3(6)WA4(9b). (CSCdk44824)

Software Modifications and Caveats

This section describes software modifications, unexpected behavior, and other miscellaneous caveats in ATM software release 11.3(6)WA4(9b).

This is because when the shutdown/no shutdown commands are performed on the subinterface the PVCs are deleted and recreated. As a result the PVCs lose their bindings to VLANs. The only workaround is to enter the atm pvc vlan command to manually create the PVC-to-VLAN bindings.
We recommend that you configure PVCs on the major interfaces and even if you configure PVCs on subinterfaces, we recommend that you do not perform shutdown and no shutdown commands on the subinterfaces. (CSCdk76407)

Software Release 11.3(5)WA4(8a)

This section contains new feature description, usage guidelines, restrictions, and differences between ATM module software releases 11.3(5)WA4(8a) and 11.3(4)WA4(7a), and provides the software modifications and caveats for the ATM module software release  11.3(5)WA4(8a).

Note ATM module software release  11.3(5)WA4(8a) is the release following ATM module software release  11.3(4)WA4(7a).

New Feature

The ATM Fabric Integration module (WS-X5165) is based on the ATM dual PHY OC-12 module (WS-X5161 or WS-X5162) and supports all the features of the ATM dual PHY OC-12 module. It is used in Catalyst 5500 switches equipped with a LightStream 1010 ATM switch processor (ASP) module and can be installed in slots 9 through 12 of the Catalyst 5500 switch.

Note To fully support the ATM Fabric Integration module, the Catalyst 5500 switch must be running supervisor engine software release 4.3(1) or later and the LightStream 1010 ASP must must be running Cisco IOS release12.0(1)W5(5) or later.

The ATM Fabric Integration module seamlessly integrates the Catalyst 5500 switching backplane and LightStream 1010 ATM backplane in a Catalyst 5500 chassis by providing an internal interface between the two switches. In addition to the bridge function, the ATM Fabric Integration module provides a single OC-12 port adapter module (PAM) for the LightStream 1010 switching fabric. This external port can be used to connect to another OC-12 device and is managed by the ASP in the LightStream 1010.

Configuration of the ATM Fabric Integration module is performed through the ASP. For configuration information, refer to the appropriate LightStream 1010 publication.

For information regarding the new commands available in ATM software release 11.3(3a)WA4(5) to support the MPC, refer to the Command Reference publication for your switch. For additional information, refer to the Release Notes for RSM, Cisco 4500, 4700, 7200, and 7500 Routers for Cisco IOS Release 11.3(3a)WA4(5) publication.

MPOA Functional Overviews

This section contains brief overviews about MPOA, MPOA client (MPC), and MPOA server (MPS). For additional information, refer to the Release Notes for RSM, Cisco 4500, 4700, 7200, and 7500 Routers for Cisco IOS Release 11.3(3a)WA4(5) publication.

Note In this document, "MPC" information refers to the Catalyst 5000 switch equipped with an ATM dual PHY OC-12 module (WS-X5161 or WS-X5162) or an ATM dual PHY OC-3 module (WS-X5167 or WS-X5168). "MPS" refers to the router or the RSM/VIP2 with an ATM interface in a Catalyst 5000 switch.

MPOA

MPOA enables the fast routing of internetwork-layer packets across a nonbroadcast, multi-access (NBMA) network such as ATM. MPOA replaces multihop routing with point-to-point routing using a direct virtual channel connection (VCC) between ingress and egress edge devices or hosts. An ingress edge device or host is defined as the point at which an inbound flow enters the MPOA system; an egress edge device or host is defined as the point at which an outbound flow exits the MPOA system.

The following components are required for an MPOA network:

An MPC identifies packets sent to an MPOA-capable router, establishes a shortcut VCC to the egress MPC, and then routes these packets directly over the shortcut VCC. An MPC can be a router or a Catalyst 5000 switch equipped with an ATM dual PHY OC-12 module (WS-X5161 or WS-X5162) or an ATM dual PHY OC-3 module (WS-X5167 or WS-X5168). An MPS can be a router or a Catalyst 5000 family Route Switch Module/Versatile Interface Processor 2 (RSM/VIP2) with an ATM interface.

A router is usually designated as an MPS, but can also be designated as an MPC. MPC on the router is primarily meant to provide router-initiated and router-terminated shortcuts for non-NBMA networks.

MPC Overview

MPC involves ingress/egress cache management, data-plane and control-plane VCC management, MPOA frame processing, and participation in MPOA protocol and MPOA flow detection. An MPC identifies packets sent to an MPOA-capable router over the NBMA network and establishes a shortcut VCC to the egress MPC, if possible. The MPC routes these packets directly over this shortcut VCC, bypassing the intermediate routers and enabling the fast routing of internetwork-layer packets across an NBMA network. The Catalyst 5000 switch can be designated as an MPC. If the Catalyst 5000 switch is configured with an RSM/VIP2 (with an ATM interface), it can be configured as an MPC or an MPS.

MPS Overview

The MPS supplies the forwarding information used by the MPCs. The MPS responds with the forwarding information after receiving a query from a client. To support the query and response functions, MPOA has adopted the NHRP. In addition, the MPS on the router can terminate shortcuts.

MPOA Configuration Tasks
