Switchover Guidelines
Switchover Guidelines
Be aware of the following guidelines when performing a switchover:
•
When you manually initiate a switchover, system messages indicate the presence of two supervisor
modules.
•
A switchover can only be performed when two supervisor modules are functioning in the switch.
•
The modules in the chassis are functioning as designed.
Verifying Switchover Possibilities
This section describes how to verify the status of the switch and the modules before a switchover.
•
Use the s
how system redundancy
status
command to ensure that the system is ready to accept a
switchover.
•
Use the
show module
command to verify the status (and presence) of a module at any time. A
sample output of the
show module
command follows:
switch#
show module

The
Status
column in the output should display an
OK
status for switching modules and an active or
HA-standby
status for supervisor modules. If the status is either
OK
or active, you can continue with
your configuration.
•
Use the
show boot auto-copy
command to verify the configuration of the auto-copy feature and if
an auto-copy to the standby supervisor module is in progress. Sample outputs of the
show boot
auto-copy
command follow:
switch#
show boot auto-copy
Auto-copy feature is enabled
switch#
show boot auto-copy list
No file currently being auto-copied
