corresponding host. When the IP&MAC Binding function is enabled, the IP and MAC relations in
the ARP table won’t be expired and renewed automatically, which effectively prevents the ARP
attack.
Some functions such as access control and bandwidth control, are based on the IP addresses to
identify the access clients. The network administrator can allocate every client a static IP,
according to which he makes the access and bandwidth rules to control the clients’ online
behavior and the bandwidth they’ve used. Some illegal users may change the IP address in order
to get higher Internet access. Enabling IP & MAC binding function can effectively prevent the IP
embezzlement.
NOTE:
After IP&MAC binding function is enabled, the IP bound to the MAC cannot be used by other
MACs. However this
MAC can use other IPs within the same segment, which are not bounded by
other MACs, to access the network.
