Command History
Usage Guidelines
When the Cisco uBR10012 router is configured with redundant PRE1 modules, the active PRE1 module
automatically synchronizes the configuration, network state information, and other information with the
standby PRE1 module, so that if a switchover occurs, the standby module can restore normal operations
quickly. You can use the
maintenance-mode command to disable this automatic synchronization of the
PRE1 modules, and to disable the reporting of any faults on the standby module to the active module.
Note The maintenance-mode command disables the ability of the Cisco uBR10012 router to switchover
PRE1 modules and should be used only while upgrading the router or troubleshooting network problems.
Examples
The following example shows how to disable the automatic PRE1 module synchronization on the
Cisco uBR10012 router and enter maintenance mode:
Router# config t
Router(config)# redundancy
Router(config-r)# maintenance-mode
Router(config-r)# exit
Router(config)#
The following example shows how to leave maintenance mode and return to normal operations, which
includes the automatic synchronization of the PRE1 modules:
Router#
config t
Router(config)# redundancy
Router(config-r)# no maintenance-mode
Router(config-r)#
exit
Router(config)#
