Group,

Voice VLAN story is really giving me hard time. We have so many experts on
this list , can't somebody explain what is the right way of configuring
Voice VLAN. I read three different workbooks CCO doc site and each has
their own solution.

This one from InternetworkExpert,

interface FastEthernet0/7
 switchport access vlan 7
 switchport voice vlan 10
 switchport priority extend cos 1
 mls qos trust cos

these guys say since 3550 port is in dynamic mode , switch automatically
form a trunk with Cisco Phone and don't require to configure port as a trunk
or access mode and no spanning tree portfast.....

I know in real life things work in a diffrent way , could some one please
calrify which way Cisco expect us to configure Voice VLAN stuff in lab so we
don't loose point in tussel of Trunk /Access/Advanced CDP/portfast
 etc...stuff.

Many thanks !!
