Switch Management Commands 2257
Examples
console(config)#stack
console(config-stack)#standby 2
switch renumber
Use the switch renumber command in Global Configuration mode to change
the identifier for a switch in the stack. 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.
Syntax
switch oldunit renumber newunit
• oldunit — The current switch identifier. (Range: 1–6)
•
newunit — The updated value of the switch identifier. (Range: 1–6)
Command Mode
Global Configuration mode
User Guidelines
This command is executed on the Management 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.
Example
The following example displays how to reconfigure switch number “1” to an
identifier of “2.”
console(config)#switch 1 renumber 2
