<strong>Stateful</strong> <strong>Switchover</strong><br />
Configuring SSO on the <strong>Cisco</strong> 7500 Series Router: Example<br />
<strong>Stateful</strong> <strong>Switchover</strong><br />
Configuration Examples<br />
In the following example, the active RSP is installed in slot 6 and the standby RSP is installed in slot 7<br />
of a <strong>Cisco</strong> 7513 router:<br />
Router# configure terminal<br />
Router(config)# hw-module slot 6 image slot0:rsp-pv-mz<br />
Router(config)# hw-module slot 7 image slot0:rsp-pv-mz<br />
Router(config)# redundancy<br />
Router(config-red)# mode sso<br />
Router(config-red)# end<br />
Router# copy running-config startup-config<br />
Configuring SSO on the <strong>Cisco</strong> 12000 Series Internet Router: Example<br />
In the following example configures SSO mode on the active RP; the standby RP is automatically reset<br />
and synchronized with the active RP.<br />
Router# configure terminal<br />
Router(config)# redundancy<br />
Router(config-red)# mode sso<br />
Router(config-red)# end<br />
Router# copy running-config startup-config<br />
Configuring Autosync LMI Sequence Numbers: Example<br />
In the following example, Frame Relay SSO is configured to support autosynchronization of LMI<br />
sequence numbers between the active RP and standby RP:<br />
Router (config)# frame-relay redundancy auto-sync lmi-sequence-numbers<br />
Verifying SSO Configuration: Examples<br />
This section provides the following configuration examples:<br />
• Verifying that SSO Is Configured on Various Platforms: Examples, page 41<br />
• Verifying that SSO Is Operating on the Device: Examples, page 43<br />
• Verifying SSO Protocols and Applications: Examples, page 44<br />
Verifying that SSO Is Configured on Various Platforms: Examples<br />
In the following several examples, the show redundancy command is used to verify that SSO is<br />
configured on the device. Sample output is provided for several platforms.<br />
<strong>Cisco</strong> 7304 Router: Example<br />
Router# show redundancy<br />
Redundant System Information :<br />
------------------------------<br />
Available system uptime = 2 minutes<br />
<strong>Switchover</strong>s system experienced = 0<br />
Standby failures = 0<br />
Last switchover reason = none<br />
Hardware Mode = Duplex<br />
Configured Redundancy Mode = SSO<br />
Operating Redundancy Mode = SSO<br />
Maintenance Mode = Disabled<br />
