Displaying And Maintaining Mff; Mff Configuration Examples; Auto-Mode Mff Configuration Example In A Tree Network - HP 6125G Configuration Manual

You can specify a server's IP address in either manual or automatic MFF mode. The server can be a
DHCP server, a server providing some other service, or the real IP address of a VRRP standby group.
After you specify a server's IP address and then an ARP request from the server is received, the MFF
device will search the IP-to-MAC address entries it has stored, and reply with the corresponding MAC
address to the server. As a result, packets from a host to a server are forwarded by the gateway, but
packets from a server to a host are not forwarded by the gateway.
To specify the IP addresses of servers:
Step
1. Enter system view.
2. Enter VLAN view.
3. Specify the IP addresses of
servers.
