Backup Database

— Indicates if the DHCP Snooping Database is enabled. The possible field values are:

–

Enable

— Enables storing allotted IP addresses in the DHCP Snooping Database.

–

Disable

— Disables storing allotted IP addresses in the DHCP Snooping Database. This is the default

value.

•

Database Update Interval

— Indicates how often the DHCP Snooping Database is updated. The possible

field range is 600 – 86400 seconds. The field default is 1200 seconds.

•

DHCP Option 82 Insertion

— DHCP Option 82 attaches authentication messages to the packets sent to

DHCP Server via TCP/IP network. The option permits network administrators to limit address allocation to
authorized hosts only. This permits network administrators to limit address allocation authorized hosts. The
possible field values are:

–

Enable

— Enables DHCP Option 82 Insertion on the device.

–

Disable

— Disables DHCP Option 82 Insertion on the device. This is the default value.

Define the fields.

Click

Apply

. The DHCP Snooping configuration is defined and the device is updated.
