(Optional) Configuring the Application Server IP Address

(Optional) Configuring the Application Server IP Address

Context

In addition to the gateway, application servers such as the DHCP, multicast, or other types of servers may be deployed on a network. You can specify IP addresses of accessible application servers on the MFF-enabled device.

NOTE:

This configuration is required only when the application servers and users are in the same VLAN.

  • When a network interface on the MFF-enabled device receives an ARP request from a specified application server, the MFF-enabled device responds with the user MAC address by default. The packets sent from the server to the user are directly forwarded without passing through the gateway.
  • If the MFF-enabled device is configured to transparently transmit ARP request packets, the device responds with the gateway MAC address. The packets sent from the server to the user are forwarded through the gateway.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run vlan vlan-id

    The VLAN view is displayed.

  3. Run mac-forced-forwarding server server-ip & <1–10>

    The application server IP address is configured.

    By default, no application server IP address is configured.
