Chapter 22 Configuring Redundancy

Dual MSFC Redundancy

You must configure both MSFCs identically.
Caution
requirements and the exceptions for Layer 3 redundancy for a single switch chassis.
We do not support configurations where the MSFCs are not configured identically.
These sections describe how to configure MSFC redundancy:
•
•
•
•
•
•
Hardware and Software Requirements
To configure Layer 3 redundancy, you must have at least one of the following configurations:
•
•
Each MSFC must be running the same release of Cisco IOS software.
Note
Layer 3 Redundancy for a Single Chassis
In a single Catalyst 6000 family chassis, you can have redundant supervisor engines, each with an
MSFC. You can configure HSRP on the MSFCs to provide transparent default gateway redundancy for
IP hosts in the network. HSRP configuration can coexist with IPX and AppleTalk configuration on the
same interfaces.
If one MSFC fails, HSRP allows one MSFC (router) to assume the function automatically of the other.
Combined with the high-availability feature of supervisor engine software release 5.4(1), this
configuration provides an added level of redundancy for your network.
You must configure both MSFCs identically.

A single chassis with two identical supervisor engine daughter card configurations:
Supervisor Engine 1 with Policy Feature Card (PFC) and MSFC or MSFC2 (both supervisor
–
engines must have the same type of MSFC)
Supervisor Engine 2 with PFC2 and MSFC2
–
Two chassis with a supervisor engine in each—You must have at least one supervisor engine in each
chassis. Each supervisor engine must be equipped with a PFC and an MSFC.
