23.5 DHCP Snooping Configure
Use this screen to enable DHCP snooping on the Switch (not on specific VLAN), specify the

The DHCP snooping database stores the current bindings on a secure, external TFTP server so
that they are still available after a restart. To open this screen, click
Advanced Application >
IP Source Guard > DHCP Snooping > Configure
.
