26.5 DHCP Snooping Configure
Use this screen to enable DHCP snooping on the Switch (not on specific VLAN),
specify the VLAN where the default DHCP server is located, and configure the
DHCP snooping database. 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.
