Manipulating Bootflash On The Standby Supervisor Engine - Cisco Catalyst 4500 series Administration Manual

Configuring
RPR and SSO on Supervisor Engine 7-E,
Supervisor Engine 7L-E,
and Supervisor Engine 8-E
Catalyst 4500 series switches allow a standby supervisor engine to take over if the active supervisor
engine fails. In software, supervisor engine redundancy is enabled by running the redundant supervisor
engine in route processor redundancy (RPR) or stateful switchover (SSO) operating mode.
Note The minimum ROMMON requirement for running SSO and RPR is 15.0(1r)SG1. VSS default mode is
SSO and is not configurable. VSS does not support RPR mode.
This chapter describes how to configure supervisor engine redundancy on the Catalyst 4507R and
Catalyst 4510R switches.
For information on Cisco nonstop forwarding (NSF) with SSO, see
