Well, what I meant (sorry for not being specific enough) was to create a
*second* link between switches and closets that all participate in a single
VLAN dedicated for RSPAN only. If you have extra fiber pairs/copper between
closets then this shouldn't be too expensive. Might have to buy some media
converters or other assorted hardware but I think it's still a good
solution. I would want to lab it up with 2 or 3 switches first though just
to see what unexpected little surprises may exist. ;-)

Hey there Rik,
I'd had a thought about that and leaving one vlan for rspan specifically,
but the problem there is that on the uplink interfaces, you have to throw in
the commands: "no switchport, ip address 1.2.3.4"
which means that no vlans will be passed over!!
