Nov 29, 2011 · Depending on the supported functionality, such switch may have one or more MAC addresses. Cisco Catalyst switches usually have one unique MAC address per physical port, plus a set of surplus MAC addresses for diverse virtual interfaces (Port-channels, Switched Virtual Interfaces).
Network devices that operate on Layer 3 such as routers as well as multi-layer switches will have multiple MAC addresses, one assigned to each network interface. MACs must be unique on a network segment, but may not be on different network segments. A MAC address is 48 bits or 6 bytes in total. We write it in hexadecimal.

In th other hand, the switch always must show you 2 mac address per port, the port MAC, and the MAC of the NIC connected to him. This one, will be stored, by default, 300 seconds. Add a comment.
Dec 22, 2023 · Learn how network switches use MAC addresses to efficiently forward data packets and manage network traffic. Understand the importance of MAC addresses in optimizing network performance.
In this lesson, I’ll demonstrate how a switch learns MAC addresses. Let me show you an example of three computers connected to a switch: There’s a switch in the middle and we have 3 computers. All computers have a MAC address but I’ve simplified them.
