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. Layer 2 switching basic concepts : Working of layer 2 switchingīefore layer 2 switch, Old bridges were used in networking.

You can read the full article related to OSI reference model here. You should know about the layered approach in a network for data packet switching. 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. Each port of switch creates it’s own collision domain. 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 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 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. We can say the Layer 2 switching basic concepts are related to receive and transmit the data packets in a network. A Switch receive and transmit the data packets between different end devices. Role of a Switch in a networkĪ Switch is a networking device which works at Data link layer in networking. In this article I describe the Layer 2 switching basic concepts with some other related terms like loop avoidance in a network. Layer 2 switching basic concepts is important part to learn for CCNA exam. 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 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 local network. In this article I describe Layer 2 switching basic concepts in networking for CCNA Exam. The estimated reading time for this Article is 11 minutes approx!
