Configure Static Bound Entries of Port IP Source Guard

Configure Static Bound Entries of Port IP Source Guard

The static bound entries of the port IP Source Guard are the basis of filtering the IP packets received by the specified port.

When the port Dynamic ARP Inspection function is enabled, only the static entries configured with mac, ip, and vlan can serve as the basis of the validity detection for the ARP packets.
