WAAS Optimization Problem


I am currently working through a try and buy of the WAAS solution.

I have a data center connected via a T1 to a remote site. I have included an image of the test design. All three appliances are WAE-512's. As noted in the visio, I am using wccp for redirection.

As of now, CIFS optimization is great. I have been surprised at how well it works. To the user, being able to transfer a 50MB file over a T1 WAN link in a matter of 10 seconds is amazing.

The problem that I'm having is all other optimizations aside from CIFS. I can transfer a 3MB FTP file between sites multiple times, and it takes a minute each time. I would expect DRE to make the results similar to what I am experiencing with CIFS.

I am seeing the same lack of results with HTTP, backups, and any other bulk-data apps.

I forgot to include on the Visio that the WAES are version 4.0.11 b34.

Under the application policy's on the WAE's, I have the following:


map adaptor WAFS transport

name WAFS All action optimize full


map other optimize full

Any ideas?

Re: WAAS Optimization Problem

When a ftp session is occuring, if you issue a show tfo connection summary, do you see the IP addresses of the current session? Is it showing all T's or F's to the right hand side?

Re: WAAS Optimization Problem

Through TAC, this was resolved this morning.

I wasn't matching the traffic in the redistribution list for wccp properly. I was matching 'permit tcp any edge-network' on the core, and 'permit tcp edge-network any' on the edge.

After adding 'permit tcp any core-network' on the core, and 'permit tcp core-network any' on the edge, everything began working.

I didn't take into account the redirected traffic. It's working great now.
