Ethernet Forwarding
The Ethernet forwarding property lets an AADvance controller forward
Ethernet packets intended for a third party device, as shown in the illustration,
together with all broadcast and multicast messages.
When Ethernet forwarding is enabled, each 9110 processor module in the
controller forwards unicast messages intended for other devices, and all
broadcast and multicast messages, between its two Ethernet ports. A device
connected through the processor module can get its IP configuration through
BOOTP or DHCP, or statically.
The processor module in the first position (slot) in the 9100 processor base
unit forwards these messages from port E1-1 to E1-2, and in the opposite
direction from port E1-2 to E1-1. Similarly (if fitted), the processor module in
the second position in the 9100 processor base unit forwards traffic from port
E2-1 to E2-2, and from port E2-2 to E2-1. The third processor module (if
