Displaying And Maintaining Mff; Mff Configuration Examples; Auto-Mode Mff Configuration Example In A Tree Network - HPE FlexNetwork 7500 Series Security Configuration Manual

As a result, packets from a host to a server are forwarded by the gateway. However, packets from a
server to a host are not 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. Instead, 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.
You can specify a server's IP address in either manual or automatic MFF mode.
To specify the IP addresses of servers:
Step
1. Enter system view.
2. Enter VLAN view.
3. Specify the IP addresses of
servers.
