The Catalyst 5000 family and 6000 family switches support a variety of ATM modules that permit transparent connections between legacy LANs over ATM backbones and enable permanent virtual connections (PVCs) 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.

ATM Switch Processor Software

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

Catalyst 5000 family and 6000 family share a command-line interface (CLI) with which you can configure modules and ports on the switches. For descriptions of the available CLI commands, see Chapter 7, "Command Reference."

Software Features

Catalyst 5000 family and 6000 family ATM modules support these software features:

•LAN emulation

•PVCs with traffic shaping

•MPOA

•Fabric integration

•Fast Simple Server Redundancy Protocol (FSSRP)

VLAN/ELAN Trunks

Emulated LANs (ELANs) effectively extend 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

Catalyst 5000 and 6000 family ATM modules can be monitored and controlled with network management, with the CLI, or with alternative methods, such as CWSI, CiscoWorks 2000, 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).
