   Feb 10, 2023 · It seems that MAC addresses are used to do an IP-MAC mapping inside a switch in a LAN, but it seems redundant since the switch already should know which port leads to which host with a given IP address.

   When a switch receives a frame, it finds the frame's source address in the CAM table. If it finds an entry for the source address, it resets the timer stored in the aging field. If it does not find an entry, it adds a new entry for the source address. Let us take an example. The following image shows a network. This network has three PCs connected ...

   A switch does not share its CAM table with others. If multiple switches are used in the network, each of them will use its own CAM table to take the forwarding decision. The following image shows a network that uses two switches.

   To view the entries of the CAM table, you can use the "show mac-address-table" command in privileged-execmode. This command displays the CAM table's entries. If you use this command just after starting the switch, it displays a blank CAM table. A switch adds a device MAC address in the CAM table when it receives a frame from that device on any of i...

   If you change a device's location, the switch receives frames from that device on another port. If a switch finds an entry for the source MAC address with different port information, it assumes that the device has been relocated. In this situation, the switch updates the port information along with the timer. This feature makes the relocation of de...

   How does a MAC address work on a network switch?

   • The switch identifies the new MAC address as a unique device and associates it with the specific port it’s connected to. If the switch’s security settings permit, the device can continue communicating on the network with its new addresses. How to specify a static MAC address for a specific port on a network switch?

   How does a network switch handle dynamic MAC addresses?

   • A network switch handles dynamic MAC addresses based on its MAC address learning function. In general scenarios, when a device connects to a switch port, the switch learns the device’s MAC address and updates its MAC address table accordingly. If a device disconnects or if its MAC address changes, the switch updates the table to reflect the change.

   How does a switch learn MAC addresses?

   • A switch can learn MAC addresses in two ways; statically or dynamically. In the static option, we manually add MAC addresses to the CAM table. In the dynamic option, the switch automatically learns and adds MAC addresses to the CAM table. Adding MAC addresses to the CAM table is a tedious task.

   Why do I need both IP addresses and MAC addresses?

   • Here’s why both IP addresses and MAC addresses are required: MAC Address (Data Link Layer – Layer 2): Used for local addressing within the same network segment. MAC addresses are hardware addresses associated with network interfaces and are used to deliver frames within the local network.

   When a device wants to send data to another specific device, it uses the unicast MAC address of the destination device. A network switch fill mac address table it actually adds unicast mac addresses and maps them to specific port when it receive some frame from different port.
