Hi all,
I currently have a WAAS network in place with 3 remote sites and a data center site running using WCCP for traffic redirection. I am looking into deploying more WAAS to a few more remote sites and I have a couple questions, hoping someone can help clearify. Thanks in advance for any inputs / suggestions !!!
Currently, I have one WAE-674 at the data center and I am looking into adding one more WAE-674 to support more remote sites. Here are my questions:
With two WAEs at the data center, how do I load balance traffic between them using WCCP ? Does WCCP load balance traffic dynamically on its own ?
Thanks again !!!

Hi,
WCCP provides reidrection as well as load balancing functionality.
Here is a URL that can help. Let me know if you have any other questions.
Thanks

Hi Eric,
One quick question. Can you please tell why I am seeing a lot of pass-through connections between two WAAS enabled sites ? I am seeing a lot of "PT in progress" under ConnType when I run the command "show stat con pass-through". I know I am not redirecting video or voice traffic to the WAE and below are all the data applications that go between these two sites. At the same time I am also seeing a lot connections being optimized.
Internet
SAP
LotusNotes email / Sametime
Cisco Agent Desktop
Windows AD
Thanks Eric !!!

Hi,
There are a couple of possible reasons for pass through connections.
1) the application is set to pass through via application traffic policy
http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/v413/configuration/guide/apx_apps.html
2) the traffic is only going through one WAE
3) the traffic goes through 2 WAE in one direction but not through the same 2 in the return path.
4) the device is overloaded
Thanks

Thanks Eric !!
I am not doing anything special to the traffic policy, I am using the default. How can I tell if the device is overloaded ? I have WAE-674 at both ends in this scenario.
Thanks again !!! I very much appreciate your help !!!

The default application policy does have a bunch of rules in pass through by default based on the characterists of the application. Analysis of the pass through connections would determine the reason.
You can take a look at show statistics pass-through and look at the overload field.
Thanks,

Hi Eric,
Below is the output from the 'show statistics pass-through' command. Could you take a look and tell me if there is anything unusual ? I do not see the field for Overload. I do not have WAAS at all locations so it makes sense to see some connections with no peer but I do see some pass-through connection where I have WAAS installed. Please let me know what you find !!! Thank you very much !!!

HI,
Interesting that this field is no longer list.
I don't see anything alarming, AFAIK. The Rjct Resources are not increasing.
pass through connections are normal, unless there is a specific entries that you believe should be optimized which aren't.
Thanks.

Hi,
Did you solve the problem.
I see a lot of PT In Progress as well and I can not figure out the source of the problem
We have 3 WAE674 (WCCP) at the core and a WAE512 (InLine) at the edge.
Regards,
Erik
