This chapter describes how to configure supervisor engine redundancy on the Catalyst 4507R and 
Catalyst 4510R switches.

This chapter consists of the following major sections:

For complete syntax and usage information for the switch commands used in this chapter, look at the 
Cisco Catalyst 4500 Series Switch Command Reference and related publications at this location:

If the command is not found in the Catalyst 4500 Command Reference, it is located in the larger Cisco 
IOS library. Refer to the Catalyst 4500 Series Switch Cisco IOS Command Reference and related 
publications at this location:

Catalyst 4500 series switches allow a standby supervisor engine to take over if the primary supervisor 
engine fails, thereby allowing the switch to resume operation quickly in the event of a supervisor engine 
failure. This capability is called supervisor engine redundancy. In software, this capability is enabled by 
route processor redundancy (RPR) operating mode.
