24.2 IP Source Guard

Use this screen to look at the current bindings for DHCP snooping and ARP inspection.
Bindings are used by DHCP snooping and ARP inspection to distinguish between authorized
and unauthorized 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 Advanced Application > IP Source Guard.

24.3 IP 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 Advanced Application > IP Source Guard > Static
Binding.

DESCRIPTION
This field displays a sequential number for each binding.
This field displays the source MAC address in the binding.
This field displays the IP address assigned to the MAC address in the
binding.
This field displays how many days, hours, minutes, and seconds the
binding is valid; for example, 2d3h4m5s means the binding is still valid for
2 days, 3 hours, 4 minutes, and 5 seconds. This field displays infinity if the
binding is always valid (for example, a static binding).
This field displays how the Switch learned the binding.
static: This binding was learned from information provided manually by an
administrator.
dhcp-snooping: This binding was learned by snooping DHCP packets.
This field displays the source VLAN ID in the binding.
This field displays the port number in the binding. If this field is blank, the
binding applies to all ports.
