Schedule Switchover; Performing Memory Tests - Cisco WS-SUP32-GE-3B - Supervisor Engine 32 Software Configuration Manual

Schedule Switchover

Schedule Switchover
The schedule switchover test is used to check the readiness of the standby supervisor engine to take over
in case the active supervisor engine fails or is taken out of service. You can run this test once or schedule
it to run on a regular (daily, weekly, or monthly) basis.
When setting the time for a schedule switchover on both supervisor engines, the switchover for the active
Note
and standby supervisor engines should be scheduled at least 10 minutes apart to reduce system downtime
if the switchover fails.
To configure a schedule switchover, perform this task:
Command
Step 1
show diagnostic content [module num]
Step 2
Router(config)# diagnostic schedule module {num |
active-sup-slot} test {test-id} {on mm dd yyyy
hh:mm} | {daily hh:mm } | {weekly day-of-week hh:mm}
This example shows how to schedule a switchover for the active supervisor engine every Friday at
10:00 PM, and switch the standby supervisor engine back to the active supervisor engine 10 minutes
after the scheduled switchover from the active supervisor engine occurs.
Router(config)# diagnostic schedule module 5 test 32 weekly Friday 22:00
Router(config)# diagnostic schedule module 6 test 32 weekly Friday 22:10
Router(config)#

Performing Memory Tests

Most online diagnostic tests do not need any special setup or configuration. However, the memory tests,
which include the TestFibTcamSSRAM and TestLinecardMemory tests, have some required tasks and
some recommended tasks that you should complete before running them.
Before you run any of the online diagnostic memory tests, perform the following tasks:
•
Turn off all background health-monitoring tests on the supervisor engine and switching modules using
Note
the no diagnostic monitor module num test all command.
