Chapter 6 Configuring Supervisor Engine Redundancy Using RPR and SSO
Configuring Supervisor Engine Redundancy
Manual Swact = Enabled
Communications = Up
client count = 21
client_notification_TMR = 240000 milliseconds
keep_alive TMR = 9000 milliseconds
keep_alive count = 0
keep_alive threshold = 18
RF debug mask = 0x0
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
Switch#
*Aug 1 13:11:16: %C4K_REDUNDANCY-3-COMMUNICATION: Communication with the peer Supervisor
has been lost
*Aug 1 13:11:16: %C4K_REDUNDANCY-3-SIMPLEX_MODE: The peer Supervisor has been lost
This example shows how to change the system configuration from SSO to RPR mode:
Switch(config)# redundancy
Switch(config-red)# mode rpr
Changing to rpr mode will reset the standby. Do you want to continue?[confirm]
Switch(config-red)# end
*Aug 1 13:11:16: %C4K_REDUNDANCY-3-COMMUNICATION: Communication with the peer Supervisor
has been lost
*Aug 1 13:11:16: %C4K_REDUNDANCY-3-SIMPLEX_MODE: The peer Supervisor has been lost
Synchronizing the Supervisor Engine Configurations
To manually synchronize the configurations used by the two supervisor engines, perform this task on the
active supervisor engine:
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 “Supervisor
Engine Redundancy Guidelines and Restrictions” section on page 6-7.
Command Purpose
Step 1
Switch(config)# redundancy
Enters redundancy configuration mode.
Step 2
Switch(config-red)# main-cpu
Enters main-cpu configuration submode.
Step 3
Switch(config-r-mc)# auto-sync {startup-config |
config-register | bootvar | standard}
Synchronizes the configuration elements.
Step 4
Switch(config-r-mc)# end
Returns to privileged EXEC mode.
Step 5
Switch# copy running-config startup-config
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).
