Manual-mode MFF configuration example in a tree network
Network requirements
As shown in Figure 142, all the devices are in VLAN 100. Host A, Host B, and Host C are configured with
IP addresses manually. They are isolated at Layer 2, and can communicate with each other through
Gateway. To ensure communication between hosts and the server, the IP address of the server is
specified on the MFF devices manually.
