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.
