Ethernet Forwarding

Ethernet forwarding enables the Ethernet ports of an AADvance controller to re-send Ethernet packets intended for a third-party device along with unicast, broadcast, and multicast messages. A device connected through the processor module gets an IP configuration through BOOTP, DHCP, or statistically. Enable Ethernet forwarding from the

Controller Configuration

dialog box. The following diagram displays Ethernet forwarding:

In Ethernet forwarding, the processor module located in the first slot of a 9100 base unit forwards the messages from port E1-1 to E1-2 and vice versa. Other processor modules fitted in the base unit behave the same way (E2-1 to E2-2 and vice versa, E3-1 to E3-2 and vice versa). In each instance, the second port represents an uplink to the network or to another network (if applicable). A device connected to the second port sees all the relevant messages passing through.

Regardless of the setting for Ethernet forwarding, the processor module consumes the intended unicast, broadcast, and multicast messages. The controller stores the setting for Ethernet forwarding when replacing any 9110 processor modules. Corrective maintenance is unaffected by Ethernet forwarding.
