If you confgure a port on a 3550 "switch voice vlan 300" and vlan 300
does not exist, it will accept the command but you must add the vlan
manually after configuring the port for the voice vlan to work. It does
not automatically create the vlan like when you configure "switch access
vlan 300".
Hope this answers your question...

One other thing about VV's (Voice Vlan's) I would like to ask.
I dont
have Voice gear at the house so I have to ask this crazy
question. Do
we need to actually create the VV on the vtp server or by just
adding
the command 'switchport voice vlan x' under the interface take
care of
everything for us?
If I had to guess I would say we would not have to create it..
hhmmmm
whatchya think?
Thanks,
scott

Mas,
Thks for the explanation,
One for more thing if we use auxiliary VLAN option then the
VLAN's
allowed
automatically are only the access vlan and voice vlan.
Now if we use the dot1q method are the VLAN's allowed listed as
all ?? /
or
is it just the native and voice vlan ??(because of the
functionality of
the
switchport voice command)
Thks
