INSTALLATION AND OPERATION MANUAL
Binding Table
Introduction
The DHCP Snooping binding table records the host information learned by DHCP snooping
function (dynamic) or set by user (static). The ARP inspection will use this table to forward or drop
the ARP packets. If the ARP packets sent by invalid host, they will be dropped. If the Lease time is
expired, the entry will be removed from the table.
Static bindings are uniquely identified by the MAC address and VLAN ID. Each MAC address and
VLAN ID can only be in one static binding. If you try to create a static binding with the same MAC
address and VLAN ID as an existing static binding, the new static binding replaces the original
one.
