Administrator Guide

Switch Management Commands 2256
This command persists across reboots, therefore, administrators should use
this command with caution during stack upgrade procedures.
Example
console(config-stack)#stack-port tengigabitethernet 1/2/1 shutdown
Disabling a stack port will cause the stack to attempt to re-converge.
Application messages will appear in the logs during stack convergence.
Before shutting down a stack link, please ensure that your stack is in an
active ring topology in order to avoid a stack split. Continue? (y/n)
console(config-stack)#no stack-port twentygigbitethernet 1/0/1 shutdown
standby
