Ip-Mac-Port Binding Commands - D-Link DES-1210-52/ME Cli Reference Manual

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 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
with the pre-configured database. If an unauthorized user tries to access an IP-MAC-port binding
enabled port, the system will block the access by dropping its packet. The maximum number of IP-MAC-
port binding entries is dependant on chip capability (e.g. the ARP table size) and storage size of the
device. For the Switch, the maximum value for the IP-MAC-port binding ARP mode is 500. The creation
of authorized users can be manually configured by CLI or Web. The function is port-based, meaning a
user can enable or disable the function on the individual port.
The IP-MAC-Port Binding commands in the Command Line Interface (CLI) are listed (along with the
appropriate parameters) in the following table:
