IMPB

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-Port Binding (IMPB) is to restrict the access to a switch to a number of
authorized users. Authorized clients can access a switch's port by either checking the pair of IP-MAC
addresses with the pre-configured database or if DHCP snooping has been enabled in which case the
switch will automatically learn the IP/MAC pairs by snooping DHCP packets and saving them to the IMPB
white list. If an unauthorized user tries to access an IP-MAC binding enabled port, the system will block
the access by dropping its packet. Active and inactive entries use the same database. The function is
port-based, meaning a user can enable or disable the function on the individual port.
