27.4 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
Advanced Application > IP Source Guard > IPv4 Source Guard Setup > Static Binding.
