3-9. IP MAC Binding
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 authorized 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.
