Switch#
This example shows how to change the system configuration from RPR to SSO mode:
Switch(config)# redundancy
Switch(config-red)# mode
Switch(config-red)# mode sso
Changing to sso mode will reset the standby. Do you want to continue?[confirm]
Switch(config-red)# end

Synchronizing the Supervisor Engine Configurations
To manually synchronize the configurations used by the two supervisor engines, perform this task on the
active supervisor engine:
Command
Step 1
Switch(config)# redundancy
Step 2
Switch(config-red)# main-cpu
Step 3
Switch(config-r-mc)# auto-sync {startup-config |
config-register | bootvar | standard}
Step 4
Switch(config-r-mc)# end
Step 5
Switch# copy running-config startup-config
Note
Configuration changes made to the redundant supervisor engine through SNMP are not synchronized to
the redundant supervisor engine. For information on how to handle this situation, see the
Engine Redundancy Guidelines and Restrictions" section on page

Configuring Supervisor Engine Redundancy Using RPR and SSO
Purpose
Enters redundancy configuration mode.
Enters main-cpu configuration submode.
Synchronizes the configuration elements.
Returns to privileged EXEC mode.
Synchronizes the running configuration in dynamic
random-access memory (DRAM) to the startup
configuration file in NVRAM.
Note
This step is not required to synchronize the
running configuration file in (DRAM).
