Yep, first thing i tried. Couple others offered some advice, might have
to do with IP Options coming in. Need to setup some filtering to see if
that will help.

Hi Chris,
You might have reviewed the following doc already, but it might help
to get a few ideas.

I even disabled the ACLs on the interfaces to see if that was the issue.
Didn't help.

Did you double check your config to dee if anything changed or got removed
and subsequently saved after your attempt to upgrade to 15M? Sometimes
commands/santax changes slightly between versions and a part of your config
may not have been carried over.
I have also seen situations where one makes changes to a config and
forgets to save it. Then a few days/weeks/months down the road, they reboot
for one reason or another (sw upgrade for example) and suddenly the change
they made previously is gone and no one notices because it was made so long
ago and forgotten.
Just a thought. Double check you config.
I see you made sure CEF was enabled.
Another thought, do you have 'log' attached to the end of any ACL's?

Subject: Re: [c-nsp] 7206VXR NPE-G1 Upgrade from 12.4 to 15.0 High CPU
Backed down to SRE, but still seeing high utilization on the IP Input
process. Have no idea why this is happening now, thought it was due to
the upgrade to 15.0. But seeing same issue back on SRE. Anything i can
do to troubleshoot? Running out of ideas.

Was looking for the additional IPv6 support in the 15.x train. Can't
find any solution to the problem, so i'll probably just move back down
to SRE4.

Don't know anything about how 15.x works on the NPE-G1/G2,
but we're staying away from it as it doesn't have any
features we need. SRE4 is nice and happy.
Mark.
