Hey Guys,

In reading the EX-series Software Guide for JUNOS10, it states the following 
limitations for tagged traffic-

Creating tagged VLANs in a series has the following limitations:
- Layer 3 interfaces do not support this feature.
- Because an access interface can only support one VLAN member, access
interfaces also do not support this feature.
- Voice over IP (VoIP) configurations do not support a range of tagged VLANs.

It's the second stipulation that I have a problem with- we have a server with 
VPS's hosted that are all currently using the same VLANID- but on the server 
(win2k8-dc) since there is only a single vlan defined on the port, it remains 
as access, not trunk.

We can fake out the Juniper (EX3200-48T running [10.0R2.10]) by creating an 
additional vlan on the server nic for another VPS, but that wastes resources 
and/or makes the configuration a little more wonky.

I messed with "vlan-tagging" on the physical interface, and it apparently will 
not play with 'family ethernet-switching' on the unit 0 of the interface, and 
demands that unit 0 take a vlan-id of 0 (not the vlan-id of the VPS'). It looks 
like most of that functionality is put together for tunneling (not for our 
operations).

Anyway, if you have run into this and found a workaround in the switch itself, 
any guidance would be appreciated.


Thanks,
