Hello,

We're facing a high cpu problem in one of our catalysts. Unfortunately
(and as usual!) there's nothing usefull in sh processes full. It says
everything is "0%" and the total is 60%. Amazing.

The strange thing is it happens in only one of our cats. The other one
is running well, below 20% with similar number os vlans and traffic.

There are only 2 differences between they. First is that the
"problematic" one has a PFC2 with hardware revision 3.2 and the "good"
one is hw level 3.3. And the other difference is the "problematic" one
has WS-X6248-RJ-45 modules with firmware 5.1(1)CSX and the "good" one
has 5.4(2) (same hardware revision).

I've been through a lot of documents in Google but could not found any
caveat related to 5.1(1)CSX revision to justify this behavior. Tried
to debug lots of information (it could be some defective vlan
"attacking" the cat), but no luck at all.

We're not running dcef since our modules doesn't support it.

Can anybody help pointing some debug procedure of pointing any
information about 5.1(1)CSX caveats (if any) ?

Here is our sh process cpu after we transfered lots of vlans to the
other cat. Thank you!

This is all you need.

This means:-

27% total CPU of which 24% is switching packets.

You are software routing some traffic.

I am not that hot on 6500.
Tunnel interfaces,

Post your config if you like.

The 4500 allows you to SPAN the CPU to find out what is being sent to
it.
Maybe the 6500 has soemhting similar.

Thank you very much! I cannot post my conf, since it has about 5k
lines
But now there's something to look for. Thank you very much for
clarifying.

Best regards.

Hello all,

Just to clarify that I've found the reason. It is some kind of L2 Loop
inside our network and we're working on it. Thank you for all answers.

Regards.
