Hi, I guess clarifications are in order.

I had requested information on configuring DU to make use of the
dual-ethernet controllers that come with a 8400. Everybody pretty much
said that an Alpha can saturate a single segment by itself. I agree!

The clarification is that I want to connect the two 8400 10-Base-T Ethernet
controllers to a multi-port bridge concentrator. Each concentrator port
is bridged thus creating a single Ethernet segment per port, but on the
same IP sub-network. So, the 8400 would run on two different Ethernet
segments.

This 'backbone' multi-port bridge concentrator already connects all our
hosts and floor concentrators in a star configuration. So, each host and
floor concentrator are on individual Ethernet segments that are
bridged together. This has the advantage of minimizing collisions and
traffic that does not belong to a particular host.

So, theoratically if the 8400 DU IP stack can load-balance on the two
Ethernet interfaces we can achieve a higher throughput by communicating
on two different Ethernet segments. The problem is that I don't want to
install a router and have the 8400 on two different IP sub-networks or assign
two IP address to the 8400 and tell half of the world to use one IP address
and the other half to use the other.

Any ideas??

Thanks to those who replied and hope this will clarify my problem.
