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 management unit in the stack or a
standalone unit. This command reboots the renumbered switch. After
renumbering a switch, it is important to let the primary 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 primary switch state is
synchronized with the standby switch. Failure to observe this caution may
result in the primary unit spontaneously resetting due to configuration
mismatch in order to re-elect a primary 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.
Example
The following example displays how to reconfigure switch number “1” to an
identifier of “2.”
