<strong>Cisco</strong> 12000 Series Internet Router: Example<br />
Router# show redundancy<br />
Active GRP in slot 4:<br />
Standby GRP in slot 5:<br />
Preferred GRP: none<br />
Operating Redundancy Mode: SSO<br />
Auto synch: startup-config running-config<br />
switchover timer 3 seconds [default]<br />
Verifying that SSO Is Operating on the Device: Examples<br />
<strong>Stateful</strong> <strong>Switchover</strong><br />
Configuration Examples<br />
In the following several examples, the show redundancy command with the states keyword is used to<br />
verify that SSO is configured on the device. Sample output is provided for several platforms.<br />
<strong>Cisco</strong> 7304 Router: Example<br />
Router# show redundancy states<br />
my state = 13 -ACTIVE<br />
peer state = 8 -STANDBY HOT<br />
Mode = Duplex<br />
Unit ID = 0<br />
Redundancy Mode (Operational) = SSO<br />
Redundancy Mode (Configured) = SSO<br />
Split Mode = Disabled<br />
Manual Swact = Enabled<br />
Communications = Up<br />
client count = 18<br />
client_notification_TMR = 30000 milliseconds<br />
RF debug mask = 0x0<br />
<strong>Cisco</strong> 7500 Series Router: Example<br />
Router# show redundancy states<br />
my state = 13 -ACTIVE<br />
peer state = 8 -STANDBY HOT<br />
Mode = Duplex<br />
Unit ID = 7<br />
