4.11 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.

Function description: The switch has IP-MAC Binding table. The maximum number of IP-MAC binding table entries is 1024. You can
create authorized users manually. The function is global, so a user can enable or disable the function for all ports on the switch.
