What device works on Layer 2 and 3?

Layer 2 switch work on layer 2 of OSI model i.e. data link layer and sends a “Frames” to destination port using MAC address table which stores the mac address of a device associated with that port….Difference between layer-2 and layer-3 switches.

What network device is used at Layer 2?

LAYER 2 NETWORKS Devices used on a Layer 2 Ethernet network include network interface cards, hubs, bridges and switches. Ethernet devices use ‘burned in’ MAC addresses to identify each host.

Which of the following components work at both Layer 2 and Layer 3 OSI?

A network switch is a multiport network bridge that uses MAC addresses to forward data at the data link layer (layer 2) of the OSI model. Some switches can also forward data at the network layer (layer 3) by additionally incorporating routing…

What are the layer 3 devices?

The layer 3 in the OSI model is the network layer. The device that comes under this layer is the router. The functions include address handling,logical address and names to physical address translation ,routing and traffic management.

What device operates at layer 3?

router
Network Layer of the OSI Model A router is a commonly utilised layer 3 device. Operating at layer 3, a router will inspect the IP and IPX addresses of incoming data packets.

What is Layer 2 network diagram?

What is Layer 3 router?

A layer 3 switch is both a switch and a router: it can be regarded as a router with multiple Ethernet ports and with switching function. layer 3 switch enable packets switching by inspecting both their IP addresses and their MAC addresses.
