Configuring Redundancy Options
4. Click SYNCHRONIZE to start the synchronization process.
If both supervisors are running v6.0 or later application software, the
switch performs the following checks after you synchronize the active
and standby supervisors:
■Version of application software.
■Startup image (app 1, app 2, cardapp 1, or cardapp 2)
If any of these settings changed during the syn chr oni zat io n, the standby
supervisor module automatically resets so that it is failover-ready. In
earlier versions of software, you had to manually reset the standby
supervisor, if these settings changed.
*Important: If you are updating the boot code, you must manually
reset the standby supervisor after synchronizing it
with the active supervisor.
* Note: For this automatic reset feature to work, the active and standby
supervisors must both be running v6.0 or later application
software. The first time that you synchronize the supervisor
modules after upgrading the active supervisor from v5.x
application software to v6.x, you must manually reset the
standby supervisor.
CLI Command To synchronize the active and standby supervisor modules, use the
following CLI command:
(configure)# cpu_redundancy synchronize
