IP Source Guard Overview
By filtering packets on a per-port basis, IP source guard prevents illegal packets from traveling through,
thus improving the network security. After receiving a packet, the port looks up the key attributes
(including IP address, MAC address and VLAN tag) of the packet in the binding entries of the IP source
guard. If there is a match, the port forwards the packet. Otherwise, the port discards the packet.
IP source guard filters packets based on the following types of binding entries:
IP-port binding entry
MAC-port binding entry
IP-MAC-port binding entry
IP-VLAN-port binding entry
MAC-VLAN-port binding entry
IP-MAC-VLAN-port binding entry
You can manually set static binding entries, or use DHCP snooping or DHCP relay to provide dynamic
binding entries. Binding is on a per-port basis. After a binding entry is configured on a port, it is effective
only to the port.
Enabling IP source guard on a port is mutually exclusive with adding the port to an aggregation group
and adding the port to a service loopback group.
