MFF operating mode.
Configuring a network port
Step
1.
Enter system view.
2.
Enter port view.
3.
Configure the port as a
network port.
Enabling periodic gateway probe
You can configure the MFF device to detect gateways periodically for the change of MAC addresses.
This feature is supported by MFF manual mode and MFF automatic mode.
The time interval for sending gateway probes is 30 seconds. To get a gateway's MAC address, MFF in
automatic mode uses the IP and MAC addresses of the first DHCP snooping entry corresponding to the
gateway as the sender IP and MAC addresses of an ARP request, and sends the ARP request to the
gateway. (In manual mode, MFF uses the IP and MAC addresses of the ARP snooping entry
corresponding to the gateway.) After that, MFF will always use this entry to detect the gateway's MAC
address, unless the entry is removed. If the entry is removed, MFF will look for another entry; if no other
entry is found for the gateway, information about the gateway is removed.
To enable periodic gateway probe:
Step
1.
Enter system view.
2.
Enter VLAN view.
3.
Enable periodic gateway
probe.
Specifying the IP addresses of servers
You need to maintain a server list on the MFF device. The list contains the IP addresses of servers in the
network to ensure communication between the servers and clients.
