2025年1月30日 · The switch maintains an address table called the MAC address table in order to efficiently switch frames between interfaces. So basically a switch stores information about the other (Ethernet interfaces) to which it is connected on a network.

2020年11月15日 · All network connectivity is based on constantly updating ARP tables, MAC address tables, routing tables and DNS tables. Network connectivity tables are comprised of addresses and associated interfaces. They are all required to enable packet forwarding between endpoints on different subnets.

2024年11月11日 · Ethernet switches store the MAC addresses of all connected devices in a table known as CAM or MAC address table and use it to make forwarding decisions. The CAM table is also known as MAC forward table, MAC filter table, …

2023年1月7日 · The MAC (Media Access Control) address is a 48-bit physical identity of a device used to uniquely identify a device in layer 2 of the OSI model. It is represented in hexadecimal. The 3 bytes of the address represent the OUI, and the last 3 bytes are unique to the device itself.

2024年8月28日 · The MAC address table, also known as the Content Addressable Memory (CAM) table, is primarily found in network switches. Its fundamental role is to map MAC addresses to their corresponding ports, thereby enabling effective frame distribution within a local area network (LAN).

The MAC address table is where the switch stores information about the other Ethernet interfaces to which it is connected on a network. The table enables the switch to send outgoing data (Ethernet frames) on the specific port required to reach its destination, instead of broadcasting the data on all ports (flooding).

A forwarding information base (FIB), also known as a forwarding table or MAC table, is most commonly used in network bridging, routing, and similar functions to find the proper output network interface controller to which the input interface should forward a packet.

The MAC address table is a construct that is maintained within the memory of switches that corresponds MAC addresses to particular interfaces and VLANs.

2015年5月12日 · A MAC address table, sometimes called a Content Addressable Memory (CAM) table, is used on Ethernet switches to determine where to forward traffic on a LAN. Now let's break this down a little bit to understand how the MAC address table is built and used by an Ethernet switch to help traffic move along the path to its destination.

A switch is a network device that interconnects host devices at Layer 2 of the OSI model. In order to perform its function correctly, it must be able to learn the MAC addresses of the connected hosts and maintain them in a MAC address table. In this article, I’ll explain…
