Chapter
Supervisor modules in slot 1 and slot 2 - Supervisor in slot 1 is
the Active supervisor and initiates Health reports to the standby
supervisor in slot 2. If the supervisor module in slot 1 is removed/
reset/failed the supervisor in slot 2 becomes the Active supervisor. If
the supervisor in slot 1 is replaced, it remains as the standby
supervisor and receives Health Reports from the Active supervisor in
slot 2. If the supervisor in slot 2 is removed/reset/failed, the
supervisor in slot 1 becomes the Active supervisor, and sends Health
Reports to the supervisor in slot 2.(If the switch is power cycled, slot
1 supervisor is the Active supervisor, unless it has failed).
* Note: The TCP/IP interfaces have MAC and IP addresses. The
standby supervisor becoming Active would assume the
IP and MAC addresses that are used by the Active
supervisor.
* Note: When a standby supervisor is installed in the switch
there is a 45 second wait period before the standby
supervisor is fully initialized.
CAUTION
Do not remove the standby supervisor module at this time.
Using the Web
Agent
To synchronize the Active and Standby Supervisor Modules by
using the Web agent:
* Note: You must synchronize the Active and Standby
Supervisor modules in order for the standby
(redundant) supervisor to use the same configuration as
the Active supervisor. Save your running configuration
to startup configuration so if the Active supervisor fails,
the current configuration information will not be lost.
By synchronizing the two supervisors, it copies the
startup configuration file to the standby supervisor. The
standby supervisor module must be reset to run the new
configuration.
The P580 and P882 Supervisor modules must be in the
same Fabric mode to synchronize.
1. Copy the running configuration to the startup configuration
from the Web agent System> System reset>Save button or
the CLI command config> copy run start.
