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. It is a dynamic table that maps MAC addresses to ports.
The command removes and corrects preloaded entries using a number of case-sensitive switches. The nbtstat -a < name > command performs a NetBIOS adapter status command on the computer name specified by < name >. The adapter status command returns the local NetBIOS name table for that computer as well as the MAC address of the
