[c-nsp] PVLAN support

[Mike Bacher]

I've been reading up on ways to use dot1q VLANs to isolate our Co-lo customers 
from one another (they are currently sharing the same subnet).  I came across an 
interesting Cisco feature called PVLAN (Private VLAN) that seems to be an 
alternative to doing dot1q and might work better in our environment.

My question is, what are the pros/cons of using PVLAN vs dot1q?  Also, I've seen 
conflicting data on what Cisco switches support PLVAN -- one document:

http://www.cisco.com/warp/public/473/90.shtml

..says that it is supported in the 2948G-L3,

"PVLANs are available on the Catalyst 6000 running CatOS 5.4 or later, on the 
Catalyst 4000, 2980G, 2980G-A, 2948G, and 4912G running CatOS 6.2 or later"

but another:

http://www.cisco.com/warp/public/473/63.html

..says it isn't..
