The DHCP snooping is a standard configuration on the simplified campus network, which is mandatory, because:

The IP authorization modes in the 802.1x authentication include Su authorization, Radius authorization, DHCP authorization, and Mixed authorization. The DHCP authorization requires the information in the entries of the DHCP snooping to authorize rights to users.

In the MAB authentication, the users’ IP address cannot be delivered. Therefore, the entries of the DHCP snooping are required to deliver the IP address of the to-be-authenticated client to the Radius server, to generate the corresponding online authentication entries.
