The mac-authen dhcp-trigger dhcp-option command enables the device to send DHCP option information to the authentication server when triggering MAC address authentication through DHCP packets.
The undo mac-authen dhcp-trigger dhcp-option command restores the default configuration.
By default, the device does not send DHCP option information to the authentication server when triggering MAC address authentication through DHCP packets.

Option82 record information about DHCP user locations and services (voice and data services). After this command is run, if the device supports the function of triggering MAC address authentication though DHCP packets, it sends Option82 information to the authentication server when triggering MAC address authentication through DHCP packets. Based on the user information recorded in Option82, the authentication server then assigns different network access rights to users with different services in different locations. This implements accurate control on the network access right of each user.
