Usage Guide
After the feature is enabled, services using DHCP Snooping binding entries generated based on
Relay requests, such as IP Source Guard/802.1x authentication, cannot be deployed. Otherwise,
users fail to access the Internet.
After the feature is enabled, the ip dhcp snooping verify mac-address command cannot be used.
Otherwise, DHCP Relay requests will be discarded and as a result, users fail to obtain addresses.
