Usage Guidelines

A Bridge Protocol Data Unit (BPDU) uses a special reserved multicast MAC address. An interface can send and receive BPDUs regardless of whether the interface is blocked. By default, the switch does not forward BPDUs at Layer 2.

Sometimes, bridge protocol packets of the devices from other vendors need to be processed as BPDUs. You can set the MAC address of such packets to the MAC address of BPDUs.

This command displays the MAC addresses of BPDUs.

Example

# Display the MAC addresses of BPDUs.

<HUAWEI> display bpdu mac-address
 Remaining configurable number: 126
