On Alcatel-Lucent 7x50 gear, VLAN IDs are only relevant to that local port. If you want to build a "VLAN" that operates like it does on a Cisco switch or something, you set up a tag on each port, and join the tags together with a L2 switching service. The tag IDs can be different on each port, or the same... it has no impact.
apologies for leaving out alcatel-lucent and any other vendor who can also do this. i mentioned only juniper and cisco in the above-quoted article because that's the limit of my own knowledge on this topic. -- Paul Vixie
