Layer 2 switches are often used to create virtual LANs (VLANs), in which the logical segmenting of the network differs from its physical segmentation. If the frame’s source address is unfamiliar, the switch sends the frame to all its other ports except the one through which the frame entered. When a frame arrives at a port of the switch, the switch examines its destination MAC address and then forwards the frame to the port to which the destination host is connected. It builds a cache (database) of these MAC addresses and the ports on the switch to which they are mapped. The Ethernet switch has become an integral part of the worlds LAN. Once installed, a Layer 2 switch learns about its connected hosts and networks by examining the source addresses of frames it receives. We cover frame flooding, switch flooding, how a switch identifies a mac address and. L2 Switches have mac addresses for certain functions like telnet, snmp etc. You could get a router, register its MAC and then use NAT to forward the packets to multiple devices. ![]() It's, to say, the unique name of a device. They do not interfere with communication between hosts and routers. Yes, the mac address is just a physical footprint. Our switch has a MAC address table and here’s. Let’s send something from H1 to H2: H1 is going to send some data meant for H2, thus it will create an Ethernet frame which has a source MAC address (AAA) and a destination MAC address (BBB). Layer 2 switches can be installed transparently into networks. Our switch has a MAC address table and it will learn where all the MAC addresses are in the network. Thus, Layer 2 switches are essentially multiport bridges that operate near wire speed and have extremely low latency. They essentially perform a bridging function between LAN segments because they forward frames based on their destination address without any concern for the network protocol being used. These switches operate at the data-link layer (or layer 2) of the Open Systems Interconnection (OSI) reference model. Click the plus icon to search for the interface or click OK next to New Interface Detected if it shows up. ![]() Click the Apple icon on the top left corner of your screen. Layer 2 Switch is a form of Ethernet switch that switches packets by looking at their physical addresses (MAC addresses). Plug the Ethernet cable into the internet connection or other device you wish to connect, then plug it into your Macs Ethernet adaptor. ![]()
