Bridge Protocol Data Units (BPDUs) frames contain information regarding the Switch ID, originating switch port, MAC address, switch port priority, switch port cost etc. And the device that deals with layer 2 to switch is making forwarding decisions based on the layer 2 addresses.
1. PDU. Terminology.
When the malicious attacker sends a BPDU on the edge port, it triggers unnecessary STP. Bridge Protocol Data Units (BPDUs) are messages exchanged between the switches inside an interconnected redundant Local Area Network (LAN). In computer networking, the Protocol Data Unit (PDU) is a single unit of packaged data transferred between network end systems. A frame is the data link layer PDU. Protocol Data Unit (PDU):
In layered architectures of communication protocol stacks, each layer implements protocols tailored to the specific type or mode of data exchange, or PDU - Personnel Dispersal Unit. Along with the data, it contains protocol-specific control information. Publisher: Cengage. A protocol data unit, or a PDU, is a unit of information that is sent by a protocol at a particular OSI layer. What is a protocol data unit (PDU)? In the seven-layer OSI model of computer networking, packet strictly refers to a protocol data unit at layer 3, the network layer. Create. PDU - Plug Distribution Unit. A unit of information sent by a protocol at a particular OSI layer. A PDU is a specific block of information transferred over a network. It is necessary to count borrowing parameters and manage collateralized debt positions (CDPs) in the protocol. Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are two of the most well-known protocols in Layer 4.

Ethernet PDU. In the layered architectures of communication protocol stacks, each layer implements protocols tailored to the specific type or mode of data exchange. A BPDU is a data message transmitted across a local area network to detect loops in network topologies. Explanation: TheProtocol Data Unitis the unit of communication at a particular layer. A PDU is composed of protocol specific control information and user data.
When working with a multilayer protocol stack, like the TCP/IP networking suite, use of the correct PDU is important when discussing protocol interactions. Many people neither use the term PDU nor the term frame, but call every unit of data traveling over a network a "packet." After collision, each host will wait for a small interval of time and again the data will be retransmitted. Pages 8 This preview shows page 3 - But, if two systems place data on the medium at the same instance, they will collide with each other, destroying the data.

A Protocol Data Unit (PDU) includes the headers, trailers and actual data. It's elementary, my dear Watson Through the exchange of bridge protocol data units (BPDUs) sent between the switches, the STP builds a
In a layered network protocol stack, the PDU varies based on layer-specific constraints and convention.
