Cisco Catalyst 6000 Series Switches

Hardware Requirements for Catalyst 6000/Catalyst 6500 Redundancy

Introduction

Cisco Catalyst 6000 series switches can be installed with dual Supervisor Engines to provide Layer-2 redundancy. When the Supervisor Engines are equipped with an Multilayer Switch Feature Card (MSFC), the dual MSFCs provide Layer-3 redundancy as well.

This document provides some simple checks you can carry out to determine if a pair of Supervisors would meet the hardware requirements for redundancy configuration if installed in a Cisco Catalyst 6000 or 6500 switch. This document provides a brief explanation of the different hardware available, part numbers, and a table with graphical representations of the hardware. A sample show module command output is also provided by clicking on the pictures in the table.

These procedures apply to Catalyst 6000 series switches running Cisco CatOS® as well as Cisco IOS® System Software. To find out more about the differences between CatOS and Cisco IOS System Software, refer to System Software Conversion from CatOS to Cisco IOS for Catalyst 6500/6000 Switches for more information.

Prerequisites

Requirements

Readers of this document should have knowledge of these topics:

The Supervisor engine, the routing engine, and the forwarding engine models must be the same on both modules for redundancy to be supported.

Note: For redundancy, there is no need for firmware to match.

To find out what kind of Supervisor module is installed in your chassis, you need the following information:

  • The Supervisor engine model: there are multiple models of Supervisor engines that can be used in Catalyst 6000 and 6500 switches. Currently, the following models can be used:

    • Supervisor Engine I (WS-X6K-SUP1-2GE )

    • Supervisor Engine IA (WS-X6K-SUP1A-2GE)

    • Supervisor Engine II (WS-X6K-SUP2-2GE)

    • Supervisor Engine 720 (WS-SUP720-BASE)

  • The forwarding engine used: depending on the module, the Supervisor can be equipped with different types of forwarding engines. Currently, the following models can be used:

    • Policy Feature Card (PFC) (WS-F6K-PFC)

    • PFC 2 (WS-F6K-PFC2)

    • Layer 2 (L2) Switching Feature Card (WS-F6020)

    • L2 Switching Feature Card II (WS-F6020A)

    • PFC3 ( WS-F6K-PFC3A )

  • The routing engine used: the Supervisor module can also be equipped with a routing engine so that your Catalyst 6000 or 6500 switch can be used as a Layer 3 (L3) switch. Currently, the following models can be used:

    • Multilayer Switch Feature Card (MSFC) (WS-F6K-MSFC)

    • Multilayer Switch Feature Card 2 (MSFC2) (WS-F6K-MSFC2)

    • Multilayer Switch Feature Card 3 (MSFC3)(WS-SUP720)

For more information on Part Numbers, refer to "Background Information" and "How to Determine the Part Number" sections in the document How to Determine the Type of Supervisor Module That Is Installed in Catalyst 6500/6000 Series Switches.

Components Used

The outputs shown in this document are based on these Catalyst 6000 series hardware and software versions:

  • Supervisor I with CatOS 8.2(1)

  • Supervisor II with Cisco IOS Software Release 12.1(20)E2

  • Supervisor 720 with CatOS 8.1(1)

  • Supervisor 720 with Cisco IOS Software 12.2(17b)SX

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

For more information on document conventions, refer to the Cisco Technical Tips Conventions.

Determining Hardware when Powered and Working

To find out what hardware is being used when the switch is powered and working, login to the Catalyst switch and issue the show module command. Depending on what type of software you are running (CatOS or Cisco IOS Software), the output displayed will be either similar to the output shown in Output One, or similar to that shown in Output Two.

When you install two Supervisor Engines, the first Supervisor Engine to come online becomes the active module; the second Supervisor Engine goes into standby mode. All administrative and network management functions, such as SNMP, command-line interface (CLI) console, Telnet, Spanning Tree Protocol (STP), Cisco Discovery Protocol (CDP), and VLAN Trunking Protocol (VTP) are processed on the active Supervisor Engine. On the standby Supervisor Engine, the console port is inactive, the module status shows as "standby" and the status for the uplink ports is shown normally.

Output One - Switches Running CatOS

This is the first example of output.

Determining Hardware when Removed from Chassis

If you remove the modules from the chassis, it is still possible to determine what type of hardware you have, and find out which part number is being used. The table below graphically represents different combinations that meet the hardware requirements for redundancy in the Cisco Catalyst 6000/6500 switch. If you click on the link above the image, a corresponding show module output is displayed.

Determining the Part Number

Once you have the information described in the previous sections, you can determine which part number matches the Catalyst switch.

Note: The amount of memory installed on the Supervisor and the MSFC should always be checked separately, as this is not always reflected in a different part number.

On Supervisor Engine I:

  • WS-X6K-SUP1-2GE: Supervisor Engine I, L2 Feature Card

  • WS-X6K-SUP1A-2GE: Supervisor Engine I, L2 Feature Card

  • WS-X6K-SUP1A-PFC: Supervisor Engine I, PFC

  • WS-X6K-SUP1A-MSFC: Supervisor Engine I, PFC, MSFC

  • WS-X6K-S1A-MSFC2: Supervisor Engine I, PFC, MSFC2

On Supervisor Engine II:

  • WS-X6K-S2-PFC2: Supervisor Engine II, PFC2

  • WS-X6K-S2-MSFC2: Supervisor Engine II, PFC2, MSFC2

  • WS-X6K-S2U-MSFC2: Supervisor Engine II with 256 MB of DRAM on the Supervisor, PFC2, 256 MB of DRAM on MSFC2

On Supervisor 720:

  • WS- SUP720: Supervisor Engine 720, Integrated Fabric, PFC3A, MSFC3

Note: In certain circumstances, the MSFC, MSFC2, or MSFC3 may not be displayed when you use the commands shown in this document. If you do not see the MSFC, MSFC2, or MSFC3 in the output from these commands, but you are sure that there is a routing engine on the Supervisor module, refer to Recover an MSFC Missing from the Supervisor Engine show module Command for more information.
