Appendix B Configuration Examples
Enabling a Second IOS Process on a Single RP Using SSO
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# redundancy
Router(config-red)# mode sso
*May 27 19:43:43.539: %CMRP-6-DUAL_IOS_REBOOT_REQUIRED: R0/0: cmand: Configuration must
be saved and the chassis must be rebooted for IOS redundancy changes to take effect
Router(config-red)# exit
Router(config)# exit
Router#show
*May 27 19:44:04.173: %SYS-5-CONFIG_I: Configured from console by user on console
The show redundancy states command output now indicates that SSO is configured but not operational:
Router# show redundancy states
my state = 13 -ACTIVE
peer state = 1 -DISABLED
Mode = Simplex
Unit ID = 48
Redundancy Mode (Operational) = Non-redundant
Redundancy Mode (Configured) = sso
Redundancy State = Non Redundant
Maintenance Mode = Disabled
Manual Swact = disabled (system is simplex (no peer unit))
Communications = Down Reason: Simplex mode
client count = 66
client_notification_TMR = 30000 milliseconds
RF debug mask = 0x0
The show platform command output continues to show a second IOS process is still not running:
Router# show platform
