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 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. The maximum number of IP-MAC binding entries is dependant on chip
capability (e.g. the ARP table size) and storage size of the device. For DES-3350SR, the maximum number of IP-MAC Binding
entries is 512. The creation of authorized users can be manually configured by CLI or Web. The function is port-based, this means
a user can enable or disable the function on the individual port.
IP-MAC Binding Port
To enable or disable IP-MAC binding on specific ports, click
IP-MAC Binding Port
in the
IP-MAC Binding
folder on the
Configuration Menu
to open the
IP-MAC Binding Ports Setting
window. Select a port or a range of ports with the
From
and
To
fields. Enable or disable the port with the
State
field. Click
Apply
to save changes.
