Catalyst 8500 MSR and CSR Documentation Differences
The Catalyst 8500 series consists of the 13-slot Catalyst 8540 chassis and the 5-slot Catalyst 8510. There are two models of each system:
•
Multiservice Switch Router (MSR)—Supports ATM interfaces.
•
A single Catalyst 8540 chassis can also support both Ethernet and ATM interfaces when used with an ATM Router Module (ARM).
This document describes the differences between the MSR and CSR models of the Catalyst 8500 Series and includes the following sections:
•
•
•
•
Because the Catalyst 8540 and Catalyst 8510 chassis are so similar and can be configured using many of the same hardware modules, the documentation, in some cases, has been combined to include both applications. This does not mean that all hardware modules and all software features are interchangeable or supported by all software images. This section lists which parts of the combined documentation does not work with the installed Catalyst 8500 CSR route processor and with the CSR Cisco IOS.
ATM Specific Documentation
This sections lists the Catalyst 8500 MSR and CSR combined documentation and it also list the chapters that are applicable only to the ATM configurations used with the Catalyst 8500 MSR.
In the ATM and Layer 3 Module Installation Guide the following interface module chapters do not work with the Catalyst 8500 CSR with the Cisco CSR IOS image and route processor installed:

Catalyst 8500 Architecture
The Catalyst 8540 MSR can be equipped with ATM router module (ARM) functionality, which provides Ethernet-to-ATM and ATM-to-ATM bridging and routing capabilities. When the ATM router module is installed, you can have both Layer 3 and ATM technologies in the same multiservice ATM switch router chassis.
The Catalyst 8540 CSR is designed to scale campus distribution and core networks. This 13-slot chassis also provides support for Layer 2 bridging, Layer 3 routing and ATM uplink capacity. The Catalyst 8540 switch processor requires two slots, with a third slot needed for redundancy. Should either of the switch processors fail, the third takes over. One slot is required for the route processor, which handles system management and control plane functions. A second route processor slot is reserved for redundancy. The remaining eight slots are used for connectivity modules. The C8541CSR-RP and C8542CSR-SP modules run the L3 Cisco IOS software.
Using ATM and Layer 3 Modules in the Same System
The ATM router module (ARM) enables the interworking or frame forwarding between ATM and Ethernet interfaces in the same Catalyst 8540. Cisco IOS Release 12.0(4)W5(11a) introduced support for the ARM and for CSR modules in an MSR chassis. (See release notes for the Catalyst 8540 MSR for Cisco IOS Release 12.0(10)W5(18c).) An MSR chassis is defined as a system with the MSR switch processor and route processor cards.
If a system uses Ethernet modules only, install the Cisco IOS software image for the CSR on the MSR route processor modules. The MSR route processor modules support all CSR modules except the ATM Uplink with Enhanced Gigabit Ethernet interface module (C85-1OC12 and C85-1OC3). See the Hardware and Software Compatibility Matrix for limitations.
Major Differences Between 8540 MSR and CSR
Although they share the same chassis and reserve the five middle slots for processor modules, the MSR and CSR systems use different sets of switch processor modules and different images. Table 1 lists the key functional differences between a Catalyst 8540 MSR and CSR system.
