Comparison of Layer 1 and Ethernet Services

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 DYMEC’s Layer 2 Managed switches feature industrial-grade reliability, network redundancy, and security features based on the IEC 62443 standard. We offer toughened, industry-specific products with multiple industry certifications, such as parts of the EN 50155 standard for rail applications, IEC 61850-3 for power automation systems, and NEMA TS2 for intelligent transportation systems. 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. The router peels off the Layer 2 Ethernet encapsulation, forwards the Layer 3 data packet, and then re-encapsulates the packet inside a new Token Ring frame. The router sends this frame out its Token Ring interface on to the segment where Host B will see a Token Ring frame containing its MAC address and process it.
