<!-- Converted from text/rtf format -->
<P><FONT FACE="Arial">Okay, I installed a new office and it has a separate building with a WAN link to the larger office. There is no PRI connection there so they rely on the WAN to get to the larger office to get to the PRI to make outbound and receive inbound calls. I have enabled QoS but we are still receiving reports of robotic or choppy voice. I decided I wanted to move up the chain created a verify policy to make sure that on each router I was seeing marked packets. Surprisingly, I have been unable to do this. I see with the command 'show policy-map int' that I am getting packets marked with dscp of EF at the router but when I try to do this on the switches I am unable to create a proper class/policy design to see the packets.</FONT></P>
<P><FONT FACE="Arial">I found a doc for the 3550 to do QoS at the wiring closet and modified that with no luck. Here's the design that isn't working:</FONT></P>
<P><FONT FACE="Arial">class-map match-any VOICE</FONT>
<BR><FONT FACE="Arial"> match access-group 1</FONT>
<BR><FONT FACE="Arial">!</FONT>
<BR><FONT FACE="Arial">!</FONT>
<BR><FONT FACE="Arial">policy-map VERIFY</FONT>
<BR><FONT FACE="Arial"> class VOICE</FONT>
<BR><FONT FACE="Arial"> set ip dscp 40 (I ultimately want to use dscp 46 but I saw some errors when I didn't have something defined in the class in the policy so I put this here. I've defined my router to watch for dscp 40 as well so I should see the counters grow there as well if I get this working.)</FONT></P>
