RE: WCCP and WAE question regarding high cpu utilization.

Hi there,

Your platform is one of the suitable/recommended models for WCCP
redirection to/from NME's but here are my suggestions:

1- Never ever use a permit any ACL with Cisco WAAS - you certainly don't
want to kick your voip traffic over to the WAAS module. First off, you
need a TCP only ACL but in this case start with a simple ACL just to
pick some "interesting" traffic. HTTP is usually a good choice.

2- I need more info to troubleshoot this. The output of the "show ip int
xxx" and "show int xxx" commands is obviously necessary. If you're not
limited by confidentiality policies I also need a full config of the
router, for instance I need to know what your QoS policy is doing.

3- If you have any, please take all the CEF killers off the config, I'm
quite sure you're aware of this, but do get rid of things like ACLs with
the log option enabled.

* If you're not comfortable with posting more details here feel free to
contact me off-list or as a best practice open a case with Cisco TAC.

Subject: WCCP and WAE question regarding high cpu utilization.

I'm using a nme-wae card in an ISR router and using wccp to redirect
traffic, all traffic.

I notice that the CPU utilization gets to 100% and when I do a "show
ip wccp" i notice CEF switched packets are zero and process switched
packets are many, leading me to believe that's the reason for high
cpu...

Any suggestions on how to fix this?
