William,
Forget the mac address, it's not related. On the interface, set the
bandwidth to 400000, which is the true speed of the interface, right? I
think then it will reflect the correct load. As far as the interface drops,
14 thousand out of almost 4 billion isn't that bad. If you're concerned
about it, bump up your input queue a little, say 150 verses the current 75.
Clear the counters then and see if it fixes it. By the way, you've got 140
drops due to no buffer. What does a 'sh buff' tell you? Email me off line,
as this is kind of OT.

> The address was not manually entered and what concerns me is the large
number of drops on the interface. The interface was isolated because of a
potential bottleneck. Two other issues I have are that if the interface load
is tied only to the output rate and all the other RSFCs have a BW of 10M and
have an output rate less than 10M. The RSFC does have 400M of bandwidth to
the 5509 backplane.
