Description This command enables DHCP snooping of DHCP messages on the SAP or SDP. Enabling DHCP
snooping on VPLS interfaces (SAPs and SDP bindings) is required where DHCP messages important
to lease state table population are received, or where Option 82 information is to be inserted. This
includes interfaces that are in the path to receive messages from either DHCP servers or from
subscribers.
Use the no form of the command to disable DHCP snooping on the specified VPLS SAP or SDP
binding.
