Syntax
mac-forced-forwarding server server-ip&<1- 1 0>
undo mac-forced-forwarding server [ server-ip&<1- 1 0> ]
View

Default level
2: System level
Parameters
server-ip&<1- 1 0>: Specifies the IP address of a server in the network. &<1- 1 0> means you can specify up
to ten server IP addresses in one command line.
Description
Use mac-forced-forwarding server to specify the IP addresses of servers.
Use undo mac-forced-forwarding server to remove the specified or all server IP addresses.
By default, no server IP address is specified.
You can use this command (in either manual or automatic MFF operating mode) to specify the IP address
of a DHCP server, the IP address of a server providing some other service, or the real IP address of a
VRRP group.
If the MFF device receives an ARP request from a server, it will search the IP-to-MAC address entries it has
stored, and reply the corresponding MAC address to the server. In this way, packets from a server to a
host are not forwarded by the gateway, but packets from a host to a server are forwarded by the
gateway.
MFF does not check whether the IP address of a server is on the same network segment as that of a
gateway, but it checks whether the IP address of a server is all-zero or all-one. An all-zero or all-one server
IP address is invalid.
If no server IP address is specified using this command, clients cannot communicate with any server.
Check that MFF is enabled before executing the mac-forced-forwarding server command.
If no IP address is specified in the undo mac-forced-forwarding server command, all specified server IP
addresses are removed.
Examples
# Specify the server at 192.168.1.100.
