<br>
Call Manager is doing DSCP based marking and not COS based, unless we talk
about different things and mean the same, it is acting as it should.<br>
<br>
Have you configured trunk toward the Call Manager? It should be an access
port.<br>

Are you just sniffing COS? Are the DSCP values correct that CallManager<br>
is sending out? RTP should be marked as DSCP EF and all SCCP,H.323,
and<br>
SIP should be marked as DSCP C3. What are your DSCP -> COS mappings
on<br>
your switch?<br>
<br>

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