The IP network layer uses a four-byte address. The Ethernet link layer uses a six-
byte MAC address. Binding these two address types together allows the
transmission of data between the layers. The primary purpose of IP-MAC binding
is to restrict the access to a switch to a number of authorized users. Only the
a
uthorized client can access the Switch’s port by checking the pair of IP-MAC
Addresses and port number with the pre-configured database. If an unauthorized
user tries to access an IP-MAC binding enabled port, the system will block the
access by dropping its packet.
