Switch receive the frame at port F0/1.Īs switch boot first time and have no MAC address database. Now let’s device A want to transmit data for device B. This processĭone with each frame received by the switch. Not stored in its MAC database then switch save the MAC address. Then switch filter the MAC address from the frame. When a frame received at any port of switch This table contains the MAC address of allĬonnected device with the switch. Physical address learning at layer 2 switching These three functions provides aįast and reliable data transfer in a network. Learning, frame forwarding and loop avoidance. The main functions of layer 2 switching are address Layer 2 switch add MAC address of connected devices to its database itself automatically. Layer 2 switch forward the frame on the basis of MAC address header on the frame. This PUD have the IP address of source and destination. A router decide to forward or drop the packet on the basis of PUD attached with packet. Layer 2 switch forward frames from one device to another. Layer 2 switch provides a fast speed data transmission in a network because its each port breaks the large collision domain.Įach port have its own collision domain. Layer 2 switches maintain MAC address table for same purpose. This table was used to transmit the data to correct receiver. The bridges maintains content addressable memory filter table. Working of layer 2 switchingīefore layer 2 switch, Old bridges were used in networking. Instead of switch, HUB define all ports in a single collision domain. Each port of the layer 2 switch have its own collision domain. Layer 2 switch break the collision domain.
Data link layer uses MAC address of devices for data transfer. Layer 2 switching done at data link layer in OSI reference model. The broadcast domain can break by creating the VLAN in switches. The latest switch are capable to create and works with VLAN in the network. Switch are used to the basic data packet forwarding function to high end configuration switching. Layer 2 and Layer 3 switch works like a bridge between the multiple devices in a computer network. Router is generally used as gateway device for all data packets of a network. The layer 2 and layer 3 switch are always placed behind the gateway device.

Switch works on its operating software which store the MAC address of devices connected with the various interfaces of switch. A switch can connect the computers via Ethernet port, Fast Ethernet port and optic fibre port. Switch inspect the header section of the received packet to check the destination IP address and MAC address then forward accordingly. A Switch receive and transmit the data packets between different end devices. What Switch in networking?Ī Switch is a device which works at Data link layer in networking.
When the destination of a data packet is beyond the LAN, the packet forwarded to the gateway router. Switch works like a relay for data transfer between end devices. Layer 2 and Layer 3 switch connects two or more different devices within a local area network.
The basic functionality of switch is to forward the data packets to its destination by MAC filtering. The data packets forwarded by switch on the basis of MAC table which is stored in its operating system. Switch forwards the data packets within the same network. In this article I describe the role and function of Layer 2 and Layer 3 switch in networking.
