Enabling the Persistent MAC Address Feature
Purpose
Enables privileged EXEC mode.
• Enter your password if prompted.
Enters global configuration mode.
Enables a time delay after a stack-master change
before the stack MAC address changes to that
of the new stack master. If the previous stack
master rejoins the stack during this period, the
stack uses that MAC address as the stack MAC
address.
You can configure the time period as 0 to 60
minutes.
• Enter the command with no value to set
the default delay of approximately 4
minutes. We recommend that you always
enter a value.
If the command is entered without a value,
the time delay appears in the
running-config file with an explicit timer
value of 4 minutes.
• Enter 0 to continue using the MAC address
of the current stack master indefinitely.
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.
