Use the DHCP Snooping Persistent Configuration page to configure the persistent location of the DHCP (Dynamic Host Configuration Protocol) snooping bindings database. The bindings database can be stored locally on the device or on a remote system somewhere else in the network. The device must be able to reach the IP address of the remote system to send bindings to a remote database.
To access this page, click Switching > DCHP Snooping > Base > Persistent in the navigation menu.

|---|---|
| Store | The location of the DHCP snooping bindings database, which is either locally on the device (Local) or on a remote system (Remote). |
| Remote IP Address | The IP address of the system on which the DHCP snooping bindings database will be stored. This field is available only if Remote is selected in the Store field. |
| Remote File Name | The file name of the DHCP snooping bindings database in which the bindings are stored. This field is available only if Remote is selected in the Store field. |
| Write Delay (Seconds) | The amount of time to wait between writing bindings information to persistent storage. This allows the device to collect as many entries as possible (new and removed) before writing them to the persistent file. |
