Enabling Persistent MAC Address

The switch stack MAC address is determined by the MAC address of the stack master. When a stack
master is removed from the stack and a new stack master takes over, the default is for the MAC address
of the new stack master to become the new stack MAC router address. However, you can enable the
persistent MAC address feature to allow a time delay before the stack MAC address changes. During this
time period, if the previous stack master rejoins the stack, the stack continues to use that MAC address

remain as stack members and do not reboot.
Two switches become stack masters. One stack
master has nine stack members. The other stack
master remains as a standalone switch.
Use the Mode button and port LEDs on the switches
to identify which switches are stack masters and
which switches belong to which stack master. For
information about using the Mode button and the
LEDs, see the hardware installation guide.
