27.5 DHCP Snooping Configure
Use this screen to enable DHCP snooping on the OLT (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.
