Manually Allocating The Stack Mac Address - Arris Ruckus ICX 7850 Series Configuration Manual

Stack Management
Stack management MAC address
When you are configuring Layer 2 protocols, such as STP, RSTP, and MSTP, on stack units, the management MAC address of the
active controller acts as the Bridge ID.

Manually allocating the stack MAC address

When a stack is enabled, "hitless-failover enable" configuration is added, and a default stack MAC address is assigned if none is
configured. The address assigned is the MAC address of the unit as shown in the output of the show stack command.
The MAC address is a hexadecimal number in the format xxxx.xxxx.xxxx.
If necessary, you can manually configure the stack to use a specific MAC address.
NOTE
The stack mac command may be useful for administrative purposes; however, it should be used with caution to
prevent duplication of MAC addresses.
To configure a stack MAC address manually, enter the following command in device configuration mode.
device# configure terminal
device(config)# stack mac 0000.0000.0011
NOTE
Enter the no form of the stack mac command to revert to the use of the active controllers' MAC address.
The following example shows the stack MAC address being configured manually as confirmed in the show running-config
command output.
ICX7750-26Q Router# configure terminal
ICX7750-26Q Router(config)# stack mac 0000.0000.0011
ICX7750-26Q Router(config)# show running-config
