the cpu reach 85 % when using cache server and return to 3% when shutdown it!!!

Dr.X

hi ,

recently i was uisng router 7206 as router gateway and the cache working fine and the max cpu was 50 %

now , i copied the config and pasted it in another router cisco 7600

every thing is fine , but i note the cpu is increasing and reached up to 85 %% !!!!!!!!!!!!!!

i just shutdown the cache server and the cpu became 3 % !!!!!!!!!!!!

which mean that the cache server is utilizng all of my cpu  .!!!!!!

actually , there are some config wasnt accepted  in 7600 which is under interface command

duplex full

speed auto

media-type rj45

negotiation auto

but i think that these lines has no affect in cache server cpu .

i will pase my config of cache with config of interfaces  ,  whch is currently in 7600

my question is how to start troubleshooting the cpu  utilization  because of cache ?

my issue  is when i was using 7206 the cpu biggest  value was 50 % when cache is full loaded . but in 7600 the utilization reached 85 % and still increasing !!

i think that  7600 router has a default config of startup config .

could this affect and make any issue ??

The 7600 has dedicated ASICs for WCCP thus the impact to the CPU is minimal.

The 7200 processes all packets on the CPU but you can alleviate this impact by using the following command under each of the interfaces where WCCP is enabled:

ip route-cache same-interface.

This will enable fast switching on packets which are switch out of the same interface they arrived.

hi , Edison

im asking about 7600 and the problem is in 7600 not in 7206 ,

do you mean configuring the command

ip route-cache same-interface.


on router 7600 ???

regards

Sorry, I misread your question. I originally read you were moving from a 7600 to a 7200. My apologies.

Can you post your redirect-list (CACHE80 and CACHE90)?

There are some caveats when building redirect-list on hardware-assisted platforms such as the 7600.

No, you don't enter the 'ip route-cache same-interface' on the 7600 box.

Edison

hi ,

its okay

im versy sorry for hiding ips  for privacy.

here is config :

Your ACL looks fine.

sorry again for hiding ips ,note that xxx is the same as xx in the redirect-list

please  dont put me down , i  want to install 7600 with cahe and wish doing  that without problems

ip wccp 80 redirect in

ip policy route-map CACHE-REDIRECT

load-interval 30

can you remove the policy route-map and see if the CPU drops?

I noticed from the output, lots of packets punted to the CPU from the PBR.

What's the reason for this PBR?

Can you add the pertinent configuration for this PBR? route-map and ACL?

Based on the show proc cpu, your issue is interrupt traffic.

Regards,

Edison

hi , mr Edison ,

the ip ploicy is just becuse i have two internet sources , and this direct my useres to the internet .

you are right ,  im noting that the internet traffic is not natural and thgouht that there is a drop  , here is a screenshot of internet graph after shutting down  cache server .

http://www7.0zz0.com/2012/07/30/15/691686492.png

as you see, the traffic is getting breaking down and up .  but this breaking wasnt  when i was using 7206

%%%%%%%%%%%%%%%%%

any way , do you think that ip policy may be the reason of the interrupting and cache problems?? if yes , how to start troubleshoot it ??

here is the config

Gateway7600#sh route-map CACHE-REDIRECT

route-map CACHE-REDIRECT, permit, sequence 5

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

im also noting that alot of matching in  this ip policy.

regards

Let's start by removing PBR from G1/1 and observe if the CPU drops.

I understand you need the PBR to distribute your user traffic but you may be having conflicting features enabled on the same interface.

Can you post the ACLs referred within the route-map?

Are you redirecting with WCCP and PBR the same src/dst ?

Engineering your network with hardware assisted platforms is quite different than with a regular IOS router.

ok , i will  test it later and give u a reply

i cant stop it now

thanks very much

regards

Looking at your output one more time, PBR isn't punting the traffic.

The output provided in the forum didn't line up correctly and I thought Punt2Host numbers were

284112859 but in reality is assigned to the GaveRoute column. Can you confirm this for me?

What version of IOS are you running on this box? Please provide the 'show ver' output.

Also, is the Cache Engine directly connected to this box?

hi , hereis the sh again , but remember , i did itwhile the cache is not working .

again , i will try to remove pbr and give u a reply when i have the chance to do it .

and here is the output
