Configuration procedure
1. Assign IP addresses to the hosts and the gateway. (Details not shown.)
2. Configure Switch A:
# Enable STP globally to make sure STP is enabled on interfaces.
[SwitchA] stp global enable
# Configure manual-mode MFF on VLAN 100.
[SwitchA] vlan 100
[SwitchA-vlan100] mac-forced-forwarding default-gateway 10.1.1.100
# Specify the IP address of the server.
[SwitchA-vlan100] mac-forced-forwarding server 10.1.1.200
# Enable ARP snooping on VLAN 100.
[SwitchA-vlan100] arp snooping enable
[SwitchA-vlan100] quit
# Configure Ten-GigabitEthernet 1/0/2 and Ten-GigabitEthernet 1/0/3 as network ports.
[SwitchA] interface ten-gigabitethernet 1/0/2
[SwitchA-Ten-GigabitEthernet1/0/2] mac-forced-forwarding network-port
[SwitchA-Ten-GigabitEthernet1/0/2] quit
[SwitchA] interface ten-gigabitethernet 1/0/3
[SwitchA-Ten-GigabitEthernet1/0/3] mac-forced-forwarding network-port
3. Configure Switch B:
# Enable STP globally to make sure STP is enabled on interfaces.
[SwitchB] stp global enable
