mac-forced-forwarding server
Function
The mac-forced-forwarding server command configures the IP address for a server on the MFF network.
The undo mac-forced-forwarding server command deletes the configured IP address of a server.
By default, no IP address is configured for servers.
Format
mac-forced-forwarding server server-ip &<1–10>
undo mac-forced-forwarding server { server-ip | all }
Parameters
| Parameter | Description | Value |
|---|---|---|
| server-ip | Specifies the IP address for a server. | The value is in dotted decimal notation. NOTE:
This IP address must be a class A, B, or C address. If the IP address is a class A address, it cannot be in the format 0.x.x.x. |
| all | Specifies IP addresses for all servers. | - |
Usage Guidelines
Usage Scenario
In addition to the gateway, application servers such as the DHCP, multicast, or another server may be deployed on a network. You can configure IP addresses for application servers and set a list of accessible application servers on the MFF-enabled device.
- 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.
Prerequisites
MFF has been enabled in a VLAN using the mac-forced-forwarding enable command.
Precautions
When the number of configured servers reaches the upper limit 10, run the undo mac-forced-forwarding server { server-ip | all } command to delete unneeded servers before you configure new servers.
This command is required only when the application servers and clients are in the same VLAN.
