<DIV><SPAN class=716350200-30072003><FONT face=Arial size=2>Yes, llq should be
supported on the ethernet interface but have not really seen a working need
for it on a lan interface. Are you experiencing voice quality problems
currently without it?</FONT></SPAN></DIV>

<DIV><SPAN class=716350200-30072003><FONT face=Arial size=2>How are you
stressing the load on the interface to make sure that you are able to test a
difference in delay? How are you measuring the delay on your
network? You would need to make sure you have congestion on the interface
so that the PQ portion of llq can kick in. Unfortunately if you are doing
this, I would expect you will likely see other issue though on the half-duplex
(assuming that this is) ethernet interface once you start to cross 40% or so
utilization as I recall. You would likely need to implement traffic
shaping on the interface as well to throttle the traffic out to a lower limit
which then the PQ could kick in with the congestion occurring now on the
interface.</FONT></SPAN></DIV>

<DIV><SPAN class=716350200-30072003><FONT face=Arial size=2>I looked at one of
the enterprise design guides listed below, but again here I don't see reference
made to running this on a lan interface on the gateway; though some time is
spent on setting up various qos levels on the switch based on dscp components
which can be set on the 3640 GW with the dial-peer subcommand "ip
qos".</FONT></SPAN></DIV>

on 3640 Ethernet IF<BR><BR></FONT></DIV>
<DIV><FONT face=Arial size=2>Hello,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm fairly new to this but am running IOS
12.1(5)T on a cisco3640 and am trying to implement some/any priority queueing
of my voice on a 10Mg Ethernet IF. It seems that you can configure
anything.. but that doesn't mean it will run, so from the release notes it
appears I cannot do CBWFQ or PQ on this interface, however the Cisco feature
navigator says I can. I tried to test them both and it seems that they
are matching correctly and being queued correctly but <STRONG>changing
the voice class queue limit seems to have no effect on the
delay</STRONG> <STRONG>of my udp packets (i.e. they are being queued
behind the tcp no matter?). So are the config commands being
ignored? (but my packet losses indicate some effect in changing queue
limit).</STRONG></FONT></DIV>
<DIV><FONT face=Arial size=2>Ultimately, what form of PQ can I run for
voice in my setup?</FONT></DIV>
