How do I run a single Fiber Trunk from 6509e switch to 2 HP Procurve Switches, for voice and data?

I have a Cisco 6509e core switch running multiple VLANs. The two VLANs I am concerned with are for the voice and employee data networks. Recently, there was a fiber circuit installed to provide connectivity to the switch between floors due to an upcoming move. Rather than ordering Cisco equipment for the new area, HP Procurve switches were purchased. I have put the Fiber circuit into trunk mode on the 6509e and the Voice Procurve. I then selected an Ethernet port to use to trunk between the switches downstairs. I was expecting all VLANs to be carried through the trunks, but this is not what occured. I can get a voice connection when the fiber is connected to the voice switch and a data connection when I connect directly to the data switch. Does anyone know what configuration needs to be done to make this set up work properly?

First thing we have to do is settle the issue of nomenclature.

In Cisco terms a trunk is a link which carries multiple VLANs.
In HP terms a trunk is aggregating multiple physical links into a single virtual link (what Cisco calls Etherchannel).

So for this discussion, lets use Cisco terminology no matter what the platform, okay?

It sounds like you need a trunk between the 6509 and the HP switches.  And you've got the Cisco end taken care of, right?

So on the HP switch you will need to tag the non-native VLAN(s).

vlan 12 ! or whatever VLANs need to go over the trunk
 tagged 24 ! this is the port which connects to the 6509

repeat those two lines changing the VLAN number for any non-native VLANs that need to go over the trunk   (because the native VLAN isn't tagged, you don't have to do anything with that VLAN).

I appreciate that and I will give it a try. I'm familiar with Cisco, but new to the HP Procurves, so this sounds like exactly what I need to know.

The explanation of nomenclature got me moving in the right direction and saved me a lot of time on this issue.
