Looking for a bit of help/guidance on CIFS Acceleration :
We have a WXC500 at our Data Centre site, and can see CIFS Acceleration from there to other remote sites (up to 6.9x acceleration)
On one of the remote sites (WXC250) I do not see any CIFS Acceleration between them and the Data Centre site in either direction.
Any help on how to diagnose the issue would be appreciated.

The first thing to check is if the configuration is the same on all devices?
Are all devices running the same software version? Which?
What does flow diagnostics tells you about the CIFS flow to/from the branch office you have an issue with? Check in Admin -> Tools -> Flow Diagnostics.

Please post a screenshoot of the details on the flow you are looking at and maybe we can help you. In general you should look for any red crosses in any of the modules.

Check if you have tunnels up in both directions
Also, if tunnel(s) is(are) down and there are firewalls/IPSec tunnels in the path, try to use UDP mode and not IPComp.
This can be configured per-tunnel per-direction.
Accept as Solution = cool !
Accept as Solution+Kudo = You are a Star !

Humm...Could it be that the CIFS session you had an issue with was established before the tunnel was established? In this case the flow would not accelerate. CIFS sessions can be very long lived, they don't timeout like say a HTTP session does.
Anyway, good that you got it sorted.
