Use this screen to look at the current bindings. You can also use this screen to 
convert dynamic binding entries to static entries by selecting the entries and 
clicking Apply. 

Bindings are used by DHCP snooping and ARP inspection to distinguish between 
authorized and unauthorized packets in the network. The Switch learns the 
dynamic bindings by snooping DHCP packets and from information provided 
manually in the Static Entry Settings screen.

To open this screen, click Security > IP Source Guard > Binding Table >
