Rebooting from a Directory
Besides a regular boot of the switch (from the certified directory), you can also force the switch to boot
from a different directory. This is useful for checking whether a new configuration or image file will boot
the switch correctly, before committing it to the certified directory.
The following steps explain the case of a switch being rebooted from the working directory, however any
user-defined directory can be specified:
1 The certified directory is used to initially boot the switch.
2 Changes are made to the configuration file and are saved to the configuration file in the working direc-
tory by using the write memory command.
3 The switch is rebooted from the working directory by using the reload from command.
To reboot the switch from the working directory, enter the following command at the prompt, along with a
timeout period (in minutes), as shown:
-> reload from working rollback-timeout 5
At the end of the timeout period, the switch will reboot again normally, as if a reload command had been
issued.
Rebooting the Switch from a directory with No Rollback Timeout
It is possible to reboot from a directory without setting a rollback timeout, in the following manner:
-> reload from working no rollback-timeout
Scheduling a Directory Reboot
It is possible to cause a directory reboot of the CMM at a future time by setting time parameters in
conjunction with the reload from command, using the in or at keywords. You will still need to specify a
rollback time-out time, or that there is no rollback.
To schedule a working directory reboot of the CMM in 3 hours and 3 minutes with no rollback time-out,
you would enter:
-> reload from working no rollback-timeout in 3:03
To schedule a working directory reboot of the CMM at 8:00pm with a rollback time-out of 10 minutes,
you would enter:
-> reload from working rollback-timeout 10 at 20:00
Cancelling a Rollback Timeout
To cancel a rollback time-out, enter the reload cancel command as shown:
-> reload cancel
