Synchronizing the Active and Standby CPUs

7-12
Refer to the Command Reference Guide for the Avaya P550R, P580, P880,
and P882 Multiservice Switches, v5.3.1 for more details about this
command.
* Note: When the redundant CPU console IP address and default
gateway are assigned and addresses are removed via the
commands:
> no cpu_redundancy slot1
> no cpu_redundancy slot2
> no cpu_redundancy gateway
The router is no longer reachable and cannot be pinged or
used by the Web Agent from redundant addresses. The
initial console IP address is still usable.
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.
