  • Binding the IP address to the port on the access switch

    Binding the IP address to the port on the access switch

    The switch uses a source IP lookup table in hardware to bind IP addresses to ports. Basing on the binding table, the switch can prevent the ARP cheating attacks with the ARP Detection feature and filter the packets that don't match the binding. You can use IP source guard (IPSG) to prevent traffic attacks if a host tries to use the IP address of its neighbor and you can enable IP source guard when DHCP snooping is enabled on an untrusted interface. You can enable or disable IP-MAC binding for the whole switch, and you can override this global setting for each port. This. Scheme 1 and scheme 2 realize the same function, that is, bind the MAC address (network card hardware address) of a specific host on a specific switch port, and scheme 3 binds the MAC address (network card hardware address) and IP address of a specific host on a specific switch port at the same.
