Re: vlans vs trunking
I would recommend tagging the interswitch links in all VLAN's, This will ensure that your Spanning-tree domain gets configured properly, If yu are using it.
Hope this helps,
Jonathan

Re: vlans vs trunking
Sound then like all you need is VLAN tagging.
As for your STP arguement, it does not hold up to scrutiny. The threat of multiple ISLs creating a quantum packet accelerator (AKA BlinkenLights) is less likely than some BDU plugging the same jumper into two drops in his/her office.

Re: vlans vs trunking
Let me try to shed some light on this:
ProCurve trunking = Link aggregation.
If you want to aggregate links (e.g. increase bandwidth 2 x 1000BaseT link) to create a pipe of 2Gbit.
Tagging:
Let's say you have two switches with Vlan 1, 2, and 3 on both and you want to connect both switches. You could run 3 seperate links between them each carrying one of the above Vlans. As you can see, this doesn't scale very well if you have lots of Vlans.
Solution: Vlan tagging.
You would have one link between the two switches. Without Vlan tagging, the switches wouldn't know what Vlan the packet came from. Solution: On this one link, the packet is tagged with an ID telling the remote switch what Vlan it's from. This scales much better although all three Vlan share the same link.
Hope this helps,
Olaf
