If MFF is enabled on the switch and VRRP is enabled on the gateway device, users connected to the switch known only the virtual MAC address and virtual IP address of the gateway. However, the gateway uses the real MAC address and IP address of the VLANIF interface as the source MAC address and source IP address of the ARP request packets it sends to probe online users. If online user probing is enabled on the gateway, set the server IP address to the real IP address of the gateway VLANIF interface on the switch.
        Run the mac-forced-forwarding server server-ip server-ip &<1-10> command in the VLAN view and set server-ip to the real IP address of the gateway VLANIF interface.
