Is switch layer 2 or 3
WitrynaLayer 2 protocols. Layer 2 protocols or network L2 protocols are a list of communication protocols used by Layer 2 devices (such as network interface cards (NIC), switches, multiport bridges, etc.) to transfer data in a wide area network, or between one node to another in a local area network. OSI model Layer 2 protocols Witryna30 lip 2013 · Layer 2 forwards data and cannot go beyond a LAN your internal network. Layer 3 does routing, WANs are used to connect LANs. if you are comparing switches layer 3 switch is just a really smart switch that can do some limited routing functions such as VLANs.

Witryna16 lip 2015 · 2 Answers. You are correct the switch only knows/cares about the MAC. When you send a ping, host#1 first generates a arp asking for the MAC of a specific ip_dst (host#2) with a MAC_dst (ffff.ffff.ffff),MAC_src (Host#1) broadcast that the switch then forwards to all ports . Once the destination host#2 receives the broadcast, the …
Witryna11 mar 2024 · Layer 2 switches are used to reduce traffic on the local network, whereas Layer 3 switches mostly used to Implement VLAN. The advantage of Layer 2 switches is that it helps to forward packets based on unique MAC addresses. The advantage of Layer 3 switches offers flow accounting and high-speed scalability. how strong are pigsWitrynaThe layer 2 and Layer 3 differs mainly in the routing function. A Layer 2 switch works with MAC addresses only and does not care about IP address or any items of higher layers. Layer 3 switch, or multilayer switch, can do all the job of a layer 2 switch and additional static routing and dynamic routing as well. how strong are phone casesWitryna6 paź 2024 · Generally, a Layer 2 switch is one of the basic equipment used to connect all network and client devices.
