Dependent on Series/Model)

User Guidelines
Upon execution, the switch is configured with the configuration information
for the new switch if any is available. The old switch configuration
information is retained; however, the original switch will be operationally
detached. This means the interfaces show as detached in show interfaces
status output and no switch type will show for the Plugged-in Model Id in the
output of the show switch command.
This command may be executed on the stack master or a standalone
unit.This command reboots the renumbered switch. After renumbering a
switch, it is important to let the master switch synchronize the NSF state
before proceeding with additional stack management operations. Use the
show nsf command to check the NSF state. If the switch shows Warm Restart
Ready as Yes, then the master switch state is synchronized with the standby
switch. Failure to observe this caution may result in the master unit
spontaneously resetting due to configuration mismatch in order to re-elect a
master unit. The range of switch numbers is 1 to maximum stack size. The
maximum stack size varies, depending on the switch model. The switch
renumber command prompt will display the valid range.
