HI guys,
I have a DS3 line with two cisco 3925 ISRs on both ends of the private line. I need to create a QOS to allow any lync traffic ( that is marked with dscp of 26) to go with highest priority and always to have sufficient bandwidth over this 42meg pipe. Does anyone has samples or examples of how to do it?

First, check to see if traffic is being matched. Use the show policy interface command.
Second, if the interface is congested with non-Lync traffic (and not Lync traffic), pinging the other side using DSCP 26 should show very little increase vs. when interface isn't congested.
