to do this. I would think it would be switched - trust dscp inbound,
set dscp outbound. Then again, not a 6500 guru.<br>

<br><font size="3">Greetings,<br>
<br>
I am attempting to configure QoS on a series of 3550s, a 3560 and our core
switch, a 4500. Currently, I am testing QoS configurations on the 3550,
but with limited success.<br>
<br>
Using auto qos would be nice, but we can't count on the handset marking
its traffic as DSCP 46 (or CoS 5) as we're using a mash-up of Cisco IP
phones, Nortel phones, etc. Therefore, we want to match traffic on our
VoIP IP network, which is currently configured to run on </font><a href="http://10.200.0.0/16" target="_blank"><font size="3" color="blue"><u>10.200.0.0/16</u></font></a><font size="3">.<br>
<br>
The issue I am having is nothing is being matched when I look at the output
of 'show policy-map interface fa0/3' (fa0/3, for example), but I can see
packets being classified as DSCP 46 when I look at the 'mls qos interface
fa0/3 stats' command.<br>
<br>
I have attached my switch's configuration (with passwords censored). Could
someone take a quick peak and let me know if they can see anything that
is missing? It could be something obvious that my now stale eyes are missing,
so a fresh pair might help.<br>
<br>
Thanks in advance for all assistance/responses.<br>
<br>
Kind regards,</font><font size="3" color="#8f8f8f"><br>
