Bridging

Once a VLAN is defined, LinkProof performs bridging among interfaces assigned to the same VLAN. Bridging within a VLAN means that LinkProof learns the MAC addresses of Ethernet frames arriving from each physical interface, and maintains a list of MAC addresses per interface.

When a frame arrives from one interface, LinkProof looks for the frame destination addresses within its address list according to the following conditions:

If the destination address is listed in the same interface of the source address, LinkProof discards the frame.

If the destination address is listed in another interface, LinkProof forwards the frame to the relevant interface.

If the address is not listed in any interface, LinkProof broadcast the frame to all interfaces participating the VLAN.

LinkProof enables you to modify the address lists by registering additional MAC addresses per interface. 

To add a MAC address to a port

1.	Select Router > ARP Table. The ARP Table pane is displayed.

2.	Select the relevant Interface Index. The Global ARP Table Update pane is displayed.

3.	In the MAC Address text box, type the MAC address.

4.	Click Set.
