Data messages exchanged across switches in an extended LAN with a spanning tree protocol topology. BPDU packets assure that data arrives at the intended destination. These packets contain information on addresses, costs, ports, and priorities. Network loop detection involves exchanging BPDU messages across bridges. Loop deletion entails placing redundant switch ports in a backup (blocked) state and shutting down selected bridge interfaces.
Bridge Protocol Data Unit. Data structure exchanged by protocols. (ex : datagrams for IP, packets for X25...).
Bridge Protocol Data Unit. Provide bridging information in a message format. BPDUs are sent across device information with in Spanning Tree configuration. BPDU packets contain information on ports, addresses, priorities, and forwarding costs.
Bridge protocol data unit. When STP is enabled, bridges send and receive spanning-tree frames, called BPDUs, at regular intervals and use the frames to maintain a loop-free network.
(Bridge Protocol Data Unit) - A message type used by bridges to exchange management and control information.
Bridging Protocol Bonding Unit
Bridge protocol data unit. A Spanning Tree Protocol hello packet that is sent out at intervals to exchange information across bridges and detect loops in a network topology.
bridge protocol data unit. Spanning-Tree Protocol hello packet that is sent out at configurable intervals to exchange information among bridges in the network. See also PDU.
Bridge Protocol Data Unit. A data unit containing information passed between connected stations regarding connection status.
Bridge Protocol Data Units (BPDUs) are messages which carry the Spanning Tree Protocol information. A switch sends a BPDU frame using the unique MAC address of the port itself as a source address, and a destination address of the STP multicast address 01:80:C2:00:00:00.
