Switch Stack Bridge ID and MAC Address
Note
We recommend assigning the highest priority value to the device that you prefer to be the stack master. This
ensures that the device is reelected as the stack master if a reelection occurs.
To change the priority value for a stack member, use the switch stack-member-number priority new
priority-value command. For more information, see the "Setting the Stack Member Priority Value" section.
The new priority value takes effect immediately but does not affect the current stack master. The new priority
value helps determine which stack member is elected as the new stack master when the current stack master
or the switch stack resets.
Switch Stack Bridge ID and MAC Address
The MAC address of the stack master determines the stack MAC address.
When the stack initializes, the MAC address of the stack master determines the bridge ID that identifies the
stack in the network.
If the stack master changes, the MAC address of the new stack master determines the new bridge ID and stack
MAC address.
If the entire switch stack reloads, the switch stack uses the MAC address of the stack master.
Persistent MAC Address on the Switch Stack
You can also configure stack MAC persistency so that the stack MAC address never changes to the new stack
master MAC address.
Stack Master Election and Reelection
The stack master is elected or reelected based on one of these factors and in the order listed:
1. The switch that is currently the stack master.
2. The switch with the highest stack member priority value.
Note
We recommend assigning the highest priority value to the switch that you prefer to be the stack master. This
ensures that the switch is reelected as stack master if a reelection occurs.
3. The switch with the lowest MAC address.
Switch Stack Configuration Files
The configuration files record these settings:
• System-level (global) configuration settings such as IP, STP, VLAN, and SNMP settings that apply to
• Stack member interface-specific configuration settings that are specific for each stack member
