Worse, some days you can't even get 7G in from a single port on a 6704
with the other 3 ports unused. We routinely have problems with ingress
interface overruns or egress interface output queue overflows on 6704
in that traffic range, and DFC doesn't make any difference.
Did you have any fabric channel on the router with
utilization over 90% while this was happening? We had a similar
problem where any one fabric channel being maxed out would cause
unrelated cards to have input buffer overruns.
