[nsp] 6500 Native IOS ACLs

Your MSFC CPU is burning time routing packets (as evident with the high
interrupt CPU).

Check your interfaces with a "sho int stat" and see if you have one or
more interfaces that have a heavy percentage of "route cache" switched
packets relative to "distributed cache".  This will tell you which
interface is causing the problem, or is it all of them.  That might give
you a more specific point to focus on.

I have a 6500 Sup2/MSFC2 running Native IOS 12.1(8b)E9 (Service Provider
w/VIP)
and I'm trying to determine if all the ACLs are processed in hardware.
There
is fairly high CPU usage, but the tcam and fm commands look normal. Any
suggestions.

The box dosn't have any DFC enabled cards and its pushing around 500Mbps
of
traffic.
