Hi All,
Quick update, It turns out that redirects were getting punted up to the
CPU even with "no ip redirects" in the config.
Split up the ranges on to 2 separate VLANs and the CPU dropped to 10%
with 0% interupts.
Thanks for your help.
Regards
David

Looks normal to me. your interrupt is only 6% ~ .
they sit around 50%~ CPU. It will not cause any problems.
This is of my 3750x Switches.
CPU utilization for five seconds: 54%/4%; one minute: 48%; five
minutes: 47%
Take a look at the following.
http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750/software/troubleshooting/cpu_util.html#wp999591
"We consider anything below 50 percent CPU utilization to be
acceptable. A sustained level of approximately 50 percent, such as
this example, is also acceptable."
Regards,
Adam.

Don't worry about that kind of cpu on these boxes. We have
dozens in
production doing only layer 2 traffic and we see usage like this:
CU234C3560XU01#show proc cpu | inc CPU
CPU utilization for five seconds: 41%/6%; one minute: 40%;
five minutes: 40%
CCRH120C3560XU01#show proc cpu | incl CPU
CPU utilization for five seconds: 43%/3%; one minute: 39%;
five minutes: 36%
CV108c3560Xu01#show proc cpu | incl CPU
CPU utilization for five seconds: 48%/10%; one minute: 43%;
five minutes: 41%
Is that with high levels of throughput?
This one is doing layer 3 routing.

Hi all,
What is the real world expected throughput on the C3560X
devices when
doing basic Layer 3 routing?
We have a customer who has a couple of these and are doing
around
50-60Mpbs, around 10Kpps and is hitting around 50% CPU and
we are
wondering if this is normal for these switches as it seems
a little high
to us.
The configuarion is very basic, couple of VLANs, HSRP and
a static route
providing a default route upsteam.
Is this normal for the WS-C3560X-24?
What is the process at fault? (show proc cpu sort and check
the first
lines).
It is mostly interrupt.
