[c-nsp] PVLAN support

With VLAN per customer you also need a subnet per customer, PVLAN
feature eliminates this requirement, i.e. all your customers share same
subnet but can't to talk to each other on layer 2.

Subject: [c-nsp] PVLAN support

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..
