Ethernet packet. The SFD (start frame delimiter) marks the end of the packet preamble. It is immediately followed by the Ethernet frame, which starts with the destination MAC address. [1] In computer networking, an Ethernet frame is a data link layer protocol data unit and uses the underlying Ethernet physical layer transport
A frame is "the unit of transmission in a link layer protocol, and consists of a link layer header followed by a packet." [2] Each frame is separated from the next by an interframe gap. A frame is a series of bits generally composed of frame synchronization bits, the packet payload, and a frame check sequence.
IEEE 802.1Q, often referred to as Dot1q, is the networking standard that supports virtual local area networking (VLANs) on an IEEE 802.3 Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames.
The original 2.94 Mbit/s Ethernet implementation had eight-bit addresses and other differences in frame format. [9] 10BASE5: 802.3-1985 (8) AUI, N, vampire tap: 500 m RG-8/U Original standard uses a single coaxial cable in which a connection is made by tapping into the single cable, drilling in to make contact with the core and the screen.
IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet.The standards are produced by the working group of the Institute of Electrical and Electronics Engineers (IEEE).

MRP is supported by several commercial industrial Ethernet switches. [5] [6] In an MRP ring, the ring manager is named Media Redundancy Manager (MRM), while ring clients are named Media Redundancy Clients (MRCs). MRM and MRC ring ports support three statuses: disabled, blocked, and forwarding: Disabled ring ports drop all the received frames.
