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
