Rebooting from the Working Directory
Besides a regular boot of the switch (from the certified directory), you can also force the switch to boot
from the working 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. (For information on saving the
working directory to the certified directory, see “Copying the Working Directory to the Certified Direc-
tory” on page 4-15.)
The following picture illustrates the case of a switch being rebooted from the working directory:
In the above diagram:
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 using the copy running-config working command, described in the section “Copying the Running
Configuration to the Working Directory” on page 4-11.
3 The switch is rebooted from the working directory using the reload working command.
When a reload working command is entered, the switch prohibits a takeover from the secondary CMM.
Switch functions will be suspended until the boot process is complete.
If you decide against using the new software booted from the working directory, the switch can revert to
the software stored in the certified directory by using the copy certified working command as described
in “Copying the Certified Directory to the Working Directory” on page 4-16, or by using the reload
command as described in “Rebooting the Switch” on page 4-9.
Note. If the switch is rebooted before using the copy certified working command, the switch will be
running from the certified directory as the working and certified directories are not the same. This behav-
ior is described in “Where is the Switch Running From?” on page 4-4.
