This has been asked and debated a number of times (check the archive).
You do NOT need to have trunking enabled for it to work... Works
perfectly fine without introducing extra complexity...
However!!! (But wait, there's more...)
If you are using a NM-based switch (I think we have one of these on the
lab now), then you can type the non-switch config in all you want, but
it will never work. There's a difference in how the switching logic
works.
But on "real" switches, it works perfectly fine without the trunk
commands.
The "mls qos" is for a different set of features depending on what trust
(or not) you are planning to do. The trusting will still work fine
without the trunk commands as well.

Subject: Cat3550 voice vlan
Hi, people,
Here is one question in Ipexpert 4.0, appendix H.
(For Cat3550)
There is a Cisco 7960 IP phone connected to fa 0/15, configure the port
as if the phone will be forwarding its voice traffic with 802.1q
information. Voice vlan is 100.
My answer:
mls qos
int fa 0/15
swi trunk encap dot1q
swi mode trunk
swi voice vlan 100.
mls qos trust cos
The solution:
int fa 0/15
swi mode access
swi voice vlan 100
I am having problem accepting this solution. Should a voice port have to
be a trunk port? Because it has to carry at least two vlans, voice, and
data? also "mls qos" is not enabled...
Anyone can help me?
Shawn
