Hello everyone, I have a few questions that I could use some help on :)..
I currently have a T1 link that has no QoS settings at all (L3). Through this link, we pass exchange traffic to offsite clients, all domain services, www traffic, and many other things.
I would like to know exactly how to configure this link so we can prioritize the exchange update traffic, and the web traffic (2nd, behind exchange).
Again, I know this isn't always recommended, but when users are transfering files back and forth between sites, the network at our offsite location runs terrible (I'm assuming that its because theres a large file being transferred, and packets aren't prioritized correctly)..
Any help is greatly appreciated.
Thanks.

Hi,
The details and recommendations regarding QoS can be found in the "Enterprise QoS Solution Reference Network Design Guide Version 3.3"
http://www.cisco.com/application/pdf/en/us/guest/netsol/ns432/c649/ccmigration_09186a008049b062.pdf
This document should pretty much answer your questions and guide you to a solution.
Hope this helps!
