Ip-Mac-Port Binding Commands - D-Link xStack DES-3200 Series Reference Manual

xStack® DES-3200 Series Layer 2 Ethernet Managed Switch 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:
