What is a MAC address table?
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).
What is MAC table and routing table?
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.
What is the difference between ARP table and MAC address table?
The ARP table is built from the replies to the ARP requests, recorded before a packet is sent on the network. The MAC address table, sometimes called a MAC Forwarding Table or Forwarding Database (FDB), holds information on the physical switch port a specific device is connected to.
How is a MAC address table built?
A switch builds its MAC address table by recording the MAC address of each device connected to each of its ports. The switch uses the information in the MAC address table to send frames destined for a specific device out the port, which has been assigned to that device.
What entries are there in MAC table?
A MAC address table can contain the following types of entries:
- Static entries, which are manually added and never age out.
- Dynamic entries, which can be manually added or dynamically learned and may age out.
- Blackhole entries, which are manually configured and never age out.

What is difference between Cam and MAC table?
When performing a MAC address table lookup, the MAC address itself is the content being queried. For any matching results, CAM will return the destination port (the associated content). Cisco uses the terms MAC address table and CAM table interchangeably.
What is the difference between Cam and MAC table?
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.
How do I make a MAC address table?
What can you track from MAC address?
The MAC address variable is an important one when it comes to tracking devices on your network. Most networks use DHCP servers so you cannot rely on tracking activity based on IP addresses only. MAC addresses are unique per device so they will give you a reliable audit trail as to what is happening on your network.
