If i'm not wrong, by enable native vlan tagging setting. It will
requires all the packets including native vlan to be tagged with vlan
information. <br><br>In this case, QoS should theorically works. I'm not sure what what's the trade-off for such setup. <br><br><div class="gmail_quote">On Fri, Jan 8, 2010 at 2:37 AM, Jason Aarons (US) <span dir="ltr"><<a href="mailto:jason.aarons@us.didata.com">jason.aarons@us.didata.com</a>></span> wrote:<br>

<p class="MsoNormal" style="margin-bottom: 12pt;">If the customer is not willing
to have additional vlan for voice and yet they wish to have QoS feature enabled
for voice<br>
<br>
By enabling vlan tagging for native vlan, will the customer lose anything in
terms of features and performance? <br>
<br>
Having such setup, will the IP phone trust the DSCP tagging from the PC connected
to it if I leave it as default? <br>
<br>
Anyone have experience in such unusual setup?</p>
