Synchronizing the Active and Standby CPUs
After installing the Active and Standby CPUs, synchronize them.
Synchronization can be done by using either the Web Agent or the
CLI.
* Note: If the Active Supervisor module and the Standby
(redundant) Supervisor module are synchronized while
the Active Supervisor module is being heavily used,
TFTP transfers from the Active Supervisor module to the
Standby Supervisor module may time out or fail.
Both Supervisor modules must be running the same
software code and be in the same fabric mode. If you
synchronize a Standby Supervisor module and the APP
code, you must reset the switch before the Standby
Supervisor module can load the new APP code.
Otherwise, failover will result in the new Active
Supervisor module running the old APP code or startup,
configuration files.
After you synchronize Supervisor modules, the standby
supervisor can only be accessed with the default
passwords. The synchronization does not synchronize
passwords.
* Note: P580 and P882 Supervisor modules must be in the same
Fabric mode (1 or 2) to communicate and to
synchronize.
Synchronizing Process
The Active supervisor performs TFTP “puts” to the Standby
supervisor to synchronize the Active and standby images and
configurations. This process takes place over an internal subnet and
VLAN. From the Active supervisor’s perspective this operation is the
same as a TFTP configuration file upload.
During synchronization of the Active and standby, the boot code,
app1 and app2 images will be synchronized. The following general
rule is used when synchronizing images:
■
If the standby's image version is lower than the Active's
image version, the Active will overwrite the app code of the
standby.
