17.3 DHCP Binding Table

Bindings are used by DHCP snooping and ARP inspection to distinguish between

authorized and unauthorized frames in the network. The Switch learns the

bindings by snooping DHCP frames (dynamic bindings) and from information

provided manually by administrators (static bindings).

Use this screen to manage static bindings for DHCP snooping and ARP inspection.

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. Click Configuration > DHCP

Snooping > DHCP Binding Table to open the following screen.
