A layer 2 switch is a type of network switch or device that works on the data link layer (OSI Layer 2) and utilizes MAC Address to determine the path through where the frames are to be forwarded. It uses hardware based switching techniques to connect and transmit data in a local area ...
Layer 2 switch A switch that works at Layer 2 (data link layer) of the OSI model and can identify MAC addresses in data frames. A Layer 2 switch is also known as an Ethernet switch. Layer 3 switch A switch that works at Layer 3 (network layer) of the OSI model and provides therou...
What is a layer 3 switch? In today's intricate enterprise networks that consist of numerous subnets and virtual LANs, the presence of a layer 3 switch holds significant importance. However, is a layer 3 switch necessary for your network? Let's delve into this matter. Introduction: To put ...
What does a Layer 2 switch do if it receives a frame with a destination MAC address that is not found in its MAC address table?() A. The frame is dropped. C. The frame is sent out all ports except the receiving port. D. An ARP request is sent out all ports except ...
What will a Layer 2 switch do if it receives a frame with a destination MAC address that is not found in its MAC address table? A. he frame is dropped. B. The frame is addressed with a broadcast MAC address and sent out all ports C. The frame is sent out all ports ...
A Layer 3 switch is a special network device that has the functionality of a router and a switch combined into one chassis. It works in our network by simply allowing connected devices that are on the same subnet or virtual LAN (VLAN) to exchange information at lightning speed, just like ...
The theory of a layer 2 switch is that when the switch receives a data packet from a certain port, it will first read the source MAC address in the packet, then read the destination MAC address in the packet, and look up the corresponding port in the address table. , if there is a...
Network switch vs. router Network switches can be easily confused with routers. However, they have different functions and operate on separate layers. Here are the main differences between a switch and a router: A network switch is a Layer 2 device on the OSI model. A router is primarily a...
Compare Layer 2 and Layer 3 network switches and learn when to use each one to create a properly functioning network
3 — the network layer. This means switches use data frames, while routers use data packets. That said, Ethernet switches also can operate at Layer 3, forwarding data based oninternet protocol(IP) address rather than MAC address. Some hardware devices can function as both a switch and router...
