Verifying that SSO Is Operating on the Device: Examples
Stateful Switchover
Configuration Examples
In the following several examples, the show redundancy command with the states keyword is used to
verify that SSO is configured on the device. Sample output is provided for several platforms.
Cisco 7304 Router: Example
Router# show redundancy states
my state = 13 -ACTIVE
peer state = 8 -STANDBY HOT
Mode = Duplex
Unit ID = 0
Redundancy Mode (Operational) = SSO
Redundancy Mode (Configured) = SSO
Split Mode = Disabled
Manual Swact = Enabled
Communications = Up
client count = 18
client_notification_TMR = 30000 milliseconds
RF debug mask = 0x0
Cisco 7500 Series Router: Example
Router# show redundancy states
my state = 13 -ACTIVE
peer state = 8 -STANDBY HOT
Mode = Duplex
Unit ID = 7
