Usage Guidelines
When you enter main-CPU redundancy configuration mode, the prompt changes to the following:
Router(config-r-mc)#
After you enter main-CPU redundancy configuration mode, you can use the
auto-sync
command to
specify which files are synchronized between the active and standby PRE1 modules. In Cisco IOS
Release 12.2(11)BC3 and later releases, you can also use the
switchover timeout
command to specify
the amount of time that the standby PRE1 module should wait when it first detects that the active PRE1
module is not active and when it initiates a switchover and becomes the active PRE1 module.
To leave main-CPU redundancy configuration mode and to return to redundancy configuration mode, use
the
exit
command.
