I dont see the wae appliance interface configured on the router. I see WAN, LAN, CM but no wae.

Also,

On the WAE , perform show wccp router to see if the routers are showing up.

On router show ip wccp to see if you are actually seeing connections being redirected.

[ropethic]

also make sure you are running at minimum IOS requirements

12.4(10), 12.4(9)T1, 12.4(11)T3, 12.4(15)T5, 12.4(20)T

Please help,

I am doing a demo for WAAS for a client,

The problem is waas is olny  optimising inbound branch connections,nothing happens to outbound traffic from the branch as per the attached..

As such the branch users are unable to get the benefit of an optimised WAN.

I have done everything based on the deployment guide.

Problem is,this has previously worked and WAAS worked successfully.

Am using inline method of interception.

Please help,am so devastated-someone please help so i can have WAAS do both inbound and outbound optimisation.

I am trying deploy WAAS in our lab. Setup in the lab is following:

Wan Router - ASA - 3560 switch - server(s)

172 network terminates on the wan router. All the server(s) terminate on the lan side.

If I deploy WAAS (with in-line module) between ASA and switch, How will it work for non compress traffic coming from other destinations?

Also, traffic going out from server only need to be compress for ingress compress traffic. Some destinations might not have a WAAS to decompress the traffic.

Thanks!

Hi WAAS Expert,

     We've been having this issue in our managed customer's network where WAEs' SNMP parameters are being changed sporadically. After thorough investigation, it was found out that this 'automatic' change in WAE's SNMP parameters are due to the wrong device group settings in the Central Manager. If the correct device group setting is not chose manually (according to Cisco TAC), CMS will choose the device group setting (usually the default profile) of a WAE sporadically. Hence, the parameters that are supposed to be loaded to a WAE with respect to its correct device group setting is changed. So, I tried to choose the correct device group setting for one WAE 'manually' and the changes took effect immediately. All this while, I thought this workaround is a temporary solution after a few months of  monitoring, the SNMP parameters of this same WAE was changed again. What could be the cause of this change in WAE's configuration when its device group setting is manually selected? Does it have something to do with an instance of any change made via CLI of CMS?
