Directs the switch to generate locally administered per-port MAC addresses.

Syntax Description

This command has no arguments or variables.


This feature is disabled by default.

Usage Guidelines

ExtremeXOS switches do not use a unique per-port MAC address when transmitting bridge protocol data units (BPDUs). As a result, switch management can become inaccessible when switch MAC addresses are learned on the wrong L2 path (corresponding to a blocking port). This command allows you to direct the switch to generate locally administered MAC addresses used by STP/RSTP/MSTP BPDUs as source MAC address instead of the switch MAC address.


The following example directs the switch to generate locally administered MAC addresses:

enable switch locally-administered-address


This command was first available in ExtremeXOS 22.3.
