PurposeCommand or Action
The stack MAC address of the previous stack master
is used until you enter the no stack-mac persistent
timer command, which immediately changes the stack
MAC address to that of the current stack master.
• Enter a time-value from 1 to 60 minutes to configure
the time period before the stack MAC address changes
to the new stack master.
The stack MAC address of the previous stack master
is used until the configured time period expires or until
you enter the no stack-mac persistent timer
command.
If you enter the no stack-mac persistent timer
command after a new stack master takes over,
before the time expires, the switch stack moves
to the current stack master MAC address.
