Ip-Mac-Port Binding Commands - D-Link DGS-1210/ME Series 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:
