73.2 IPv4 Source Guard

Use this screen to look at the current bindings for DHCP snooping and ARP inspection. Bindings are used
by ARP inspection to distinguish between authorized and unauthorized ARP packets in the network. The
Switch learns the bindings by snooping DHCP packets (dynamic bindings) and from information
provided manually by administrators (static bindings). To open this screen, click SECURITY > IPv4 Source
Guard > IP Source Guard.

73.3 IPv4 Source Guard Static Binding

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. To open this screen, click
SECURITY > IPv4 Source Guard > IP Source Guard > Static Binding.

This field displays the source MAC address in the binding.
This field displays the port number in the binding. If this field is blank, the binding applies to all

seconds. This field displays infinity if the binding is always valid (for example, a static binding).
