Product Overview

Product Overview

The Catalyst 5000 family and 6000 family switches support a variety of ATM modules. These ATM modules permit transparent connections between legacy LANs over ATM backbones and enable Permanent Virtual Connection (PVC) connections between Catalyst 5000, 6000, and ATM core switches. The modules also support PVC traffic shaping, Multiprotocol over ATM (MPOA), Fast Simple Server Redundancy Protocol (FSSRP), and ATM fabric integration.

This chapter consists of the following sections:

ATM Modules Overview

Note For installation information and a complete description of the Catalyst 5000 family ATM modules, refer to the Catalyst 5000 Series Installation Guide, the Catalyst 5000 Series Supervisor Engine Installation Guide, and the Catalyst 5000 Series Module Installation Guide. For installation information and a complete description of the Catalyst 6000 family ATM modules, refer to the Catalyst 6000/6500 Series Installation Guide, the Catalyst 6000/6500 Family Module Installation Guide.

ATM Switch Processor Software

ATM modules require an additional software image, which is factory installed on the module.

The Catalyst 5000 family and 6000 family switches share a command-line interface (CLI) with which you can configure modules and ports on the switches. For descriptions of the available CLI commands, refer to "Command Reference."

Software Features

The ATM modules for the Catalyst 5000 family and 6000 family switches support these software features:

VLAN/ELAN Trunks

Emulated LANs (ELANs) effectively extend Virtual LANs (VLANs) across an ATM cloud. When you configure an ELAN, it is by default bound to a VLAN. Using ELANs you can connect members of the same VLANs on different devices over an ATM link.

Network Management

The ATM modules supported on the Catalyst 5000 family and 6000 family switches can be monitored and controlled with network management, with the CLI, or with alternative methods, such as CWSI and SNMP. For information on SNMP, refer to the Software Configuration Guide for your switch.

ATM MIBs

Table 1-3 shows the supported MIB objects for the ATM software releases.

For additional information on MIBs, RMON groups, and traps, refer to the Cisco public MIB directory (http://www.cisco.com/public/mibs/) and the "Enterprise MIB User Quick Reference," on Cisco Connection Online (CCO).
