What is Layer 2 and Layer 3 traffic?
Layer 2 vs Layer 3 switches Devices in an Ethernet network are identified by a MAC (media access control) address, which is generally hardcoded to a particular device and doesn’t normally change. Layer 3 is the network layer and its protocol is the Internet Protocol or IP.
What is Layer 2 and Layer 3 address?
The layer 3 address is a logical address. It will pertain to a single protocol (such as IP, IPX, or Appletalk). The layer 2 address is a physical address. It pertains to the actual hardware interface (NIC) in the computer.
What’s the difference between a layer 2 and a layer 3 switch?
A Layer 2 switch works with MAC addresses only and does not care about IP address or any items of higher layers. A Layer 3 switch can do all the job that a Layer 2 switch does. Additionally, it can do static routing and dynamic routing. That means, a Layer 3 switch has both MAC address table and IP routing table,…
Can a layer 3 port connect to a layer 2 port?
The idea is that one end of the link is a layer 3 interface on a router. The other end is a switchport trunk, on a vlan with an IP interface. They should be able to communicate, no?
Which is the third layer of a network?
Layer 3 is the network layer. This is where we send information between and across networks through the use of routers. Instead of just node-to-node communication, we can now do network-to-network communication. Routers are the workhorse of Layer 3 – we couldn’t have Layer 3 without them.
What are the two sublayers of Layer 2?
There are two distinct sublayers within Layer 2: Media Access Control (MAC): the MAC sublayer handles the assignment of a hardware identification number, called a MAC address, that uniquely identifies each device on a network. No two devices should have the same MAC address. The MAC address is assigned at the point of manufacturing.
