The DHCP Binding screen displays DHCP binding information such as expiry time, client IP
addresses and their MAC address.
Controllers and service platforms build and maintain a DHCP snooping table (DHCP binding
database). A controller or service platform uses the snooping table to identify and filter untrusted
messages. The DHCP binding database keeps track of DHCP addresses assigned to ports, as well
as filtering DHCP messages from untrusted ports. Incoming packets received on untrusted ports,
are dropped if the source MAC address does not match the MAC in the binding table.
To view the DHCP binding information:
1. Select the Statistics menu from the Web UI.
2. Select a Wireless Controller node from the left navigation pane.
3. Expand the DHCP Server menu from the left-hand side of the UI.
4. Select Bindings.
