WAAS Optimization problem

Ali Cavit Davutoglu — Wed, 30 Jun 2010 07:41:13 GMT

Hello experts,

I have a problem about the WAAS optimization.

The topology is...

Center: 7200 Router working with WCCP (512 WAE)

Edge: 2800 Router working with WCCP (612 WAE)

When i tried to reach the Database (behind the 7200 Router) from the Edge site. its working! but during this time, when i look the Current Connection status, there is no optimization traffic(you can see the attach file).

I have done this setup, demo etc. too many times, but the first time i encountered such a problem.

you can see the configuration at the below.

By the way, when i look the "show ip wccp" command output. there is no traffic on Service identifier 62. Do we need to see increased this traffic?

Thanks in advance for your help.

Is the traffic going over the GRE tunnel between these sites? Based on the output you provided, I suspect you need to apply ip wccp redirect 62 in on the tunnel interface itself.

Zach

Hello Zach,

Yes, the traffic going over the gre tunnel between the sites. When i tried to apply the "ip wccp redirect 62" command under the tunnel interface. I can not reach the edge router (with telnet, ssh or etc.)

I think, the problem occurs from the IPSEC traffic or something securtiy issue or MTU size. I also check the documents(cisco.com) for both situation, but everything seems to be ok.

bythe way

If you need any command output, i can provide. also routers configuration (i can email to you.)

thanks.

Can you tell me what IOS version you are running and provide a copy of the your router configuration?

Thanks,

Hi Zach

Center router IOS version is c7200-advipservicesk9_li-mz.124-11.T.bin

Edge router IOS version is c2800nm-adventerprisek9-mz.124-9.T2.bin

Also you can see the configurations at the attach

Thanks,

My best.

Hi Zach,

Is there any update about the problem?

thanks

Zach Seils — Tue, 06 Jul 2010 14:05:26 GMT

It's possible that you are running into IOS defect CSCsg30875. Can you try using an access-list with the WCCP services that excludes traffic destined to the router IP addresses?

Thanks,

Zach

Hi Zach,

it's working now,

when i apply the ip wccp command to tunnel interface, with exclude the all telnet and ssh traffic. Optimization working fine, somehow when i have downloaded something from the internet, i cant see the any compression about HTTP traffic. (I choose the FULL optimization for HTTP traffic)

anyway i am working on this problem... thank you very much for your help.

My Best

Cavit Davutoglu.

Thanks for the update Cavit.

Please feel free to create a new post if you want to troubleshoot the HTTP acceleration problem.
