Since the switch software image needed to support the TMS zl Modules is in the secondary flash,
issue the boot set-default flash secondary command so that it becomes the default boot image
and then boot the standby management module in slot MM1. Remember, the current switch
software version remains in the primary flash and, in the unlikely event of an issue with the new
switch software, may be reverted to by selecting the primary flash during the boot cycle.
The first yellow highlighted line shows that the switch is configured to boot from its primary
flash by default. After issuing the boot set-default flash secondary command in the second
yellow highlighted line, the third yellow highlighted line now shows that the switch defaults to
its secondary flash for all boot commands. Issue the boot standby command to boot the standby
management module in slot MM1 from the new switch software in the secondary flash.
It will take several minutes for the standby module to complete rebooting from the new switch
software in the secondary flash. While rebooting, it will show states of “Failed,” then
“Unknown,” and finally “Standby” in the show redundancy, show version and show modules
commands. If it is desired to track the state of the standby module as it transitions through these
states, issue any one of these commands (e.g. show redundancy) and then repeat to cause the
system to automatically repeat the command every 5 seconds.
Note: To review the switch’s local log messages that are generated as a result of booting
the standby management module and forcing the redundancy switchover use the show
logging -r command to show the local log in reverse (newest to oldest) order.
