To manually do what you are asking (I think) do the following:
(Assuming the port is ge.1.4, data VLAN is 150 and voice VLAN is 120)
set port vlan ge.1.4 150 modify (the modify removes the port from all other VLANs )
set vlan egress 120 ge.1.4 tagged
show port egress ge.1.4 should now say something like
Port Vlan Egress Registration
Number Id Status Status
------------------------------------------------------------
ge.1.4 150 untagged static
ge.1.4 120 tagged static
You need to have the phone sending voice out tagged on vlan 1319 and the data port
on the phone will be 1306.
I strongly advise the use of the "modify" portion of the command to remove all other VLANs
on the port. Without it, it is possible to put multiple UNTAGGED VLANs onto a port and
get you and the data flow very confused. (Outbound from the switch would be no problem,
but inbound...)
You build trunk ports exactly the same way. Set vlan egress for each VLAN; the old assignments
remain. (clear vlan egress to remove a particular VLAN from a port)
