21.2 IP Source Guard
Use this screen to look at the current bindings for ARP inspection. Bindings are used by ARP
inspection to distinguish between authorized and unauthorized packets in the network. The
Switch learns the bindings from information provided manually by administrators (static
bindings). To open this screen, click
Advanced Application > IP Source Guard .
Figure 91 Advanced Application > IP Source Guard
The following table describes the labels in this screen.
21.3 IP Source Guard Static Binding
Use this screen to manage static bindings for 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 .
