<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Hi All.</span> <br>
<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>I implemented
QOS on the LAN this weekend in our shop. I configured 6 closets running a
slew of 3750's and four 6500 CAT switches (with a few 6x48 blades). I
have one issue so far. I'm sniffing one of the Call Manager interfaces on
the switch and all packets coming into the CallManager seem to have the correct
COS assigned. All of the packets sourced by CallManager are COS = 0.
This makes it look like CallManager is changing these packets to 0.
Did I miss something on CallManager that I need to enable? The
clusterwide parameters (System - QOS) under Service Parameters is set to Normal
Priority, EF, AF41 and CS3. </span> <br>
<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Running
CallManager 4.1.3sr5d</span> <br>
<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Thanks,</span> <br>
