The data link layer, or layer 2, is the second layer of the seven-layer OSI model of computer networking. This layer is the protocol layer that transfers data between nodes on a network segment across the physical layer. The data link layer provides the functional and procedural means to transfer data between network entities and might provide the means to detect and possibly correct errors that may occur in the physical layer. The data link layer is concerned with local delivery of frames betwe When an Ethernet frame arrives at a Layer 2 device, the Layer 2 device will inspect the destination MAC address of the frame and look to its FDB table for information on where to send that specific Ethernet frame. Optimizing Your Network for Layer 2 Your Layer 2 data will only be as good as your network configuration. Layer 2 is equivalent to the link layer (the lowest layer) in the TCP/IP network model. Layer2 is the network layer used to transfer data between adjacent network nodes in a wide area network or between nodes on the same local area network. A frame is a protocol data unit, the smallest unit of bits on a Layer 2 network. Ethernet's Layer 2 specifications relate to the creation, forwarding, reception, and interpretation of Ethernet frames. The original Ethernet specifications were owned by the combination of Digital Equipment Corp., Intel, and Xerox—hence the name "Ethernet (DIX)." Nov 15, 2016 · Layer 2 provides the procedural and functional means for data transfer between network nodes and provides the means to detect and correct errors that may occur at the physical layer (Layer 1). Ethernet, which is used for multi-node local area networks (LAN), is the best example of the data link layer protocol. DESCRIPTION LLEAprovides layer 2 security by allowing two layer 2 network segments to be securely bridged across an insecure network segment such as layer 2 cloud services. They are used in pairs to create a point-to-point layer 2 tunnel between the two layer 2 segments.
2014-10-3 · a layer-2 network designed to be backwards compatible with Ethernet and scalable to tens of thousands of switches and millions of end hosts. Such large-scale networks are needed for emerging applications including data center networks, wide area networks, and metro Ethernet. ROME is based upon a recently developed greedy routing protocol

LAYER 2 - The data layer is where upper layer information (Layers 3-7) is encapsulated into a frame. This is also where the MAC address information is added. To be clear, at this layer your data is referenced as a frame and not an IP packet. LAYER 3 - The network layer is where upper layer information (Layers 4 -7) is encapsulated into a IP packet. If you have a 2950 switches everywhere then thats were you would use Layer 2 etherchannel. If you have 3550 switches or above then thats were you would use Layer 3 etherchannel. Aug 31, 2010 · Layer 2--data link layer--encryption is a high-performance security option that offers some advantages over Layer 3--networking layer--encryption in some scenarios, particularly in unified communications environments that require low-latency, high-volume data transmission. The increased availability and popularity of high-speed carrier Ethernet services provide fast, relatively cheap
Nov 13, 2019 · Network switches operate at Layer 2 (data link) of the OSI model while network routers operate at Layer 3 (network). This distinction leads to confusion over the definition and purpose of a Layer 3 switch, also called a multilayer switch.

Functionality of Layer 2 and Layer 3 Switch – A Layer 2 switch can only switch packets from one port to another, where as a Layer 3 switch is capable of both switching as well as routing. Well, routing is not possible in Layer 2 switching, which means devices can communicate within the same network.
