[c-nsp] Fast Uplink and 802.1w [7:91080]

[Howard C. Berkowitz]

I've been hunting through CCO documentation, and the guide
"Configuring MST/RSTP on Cat Series Switches Running CatOS" seems
incomplete. It seems to focus on MST much more than RSTP (802.1w).

  From the standard, my understanding is that 802.1w has the built-in
capability of doing things functionally equivalent to FastUplink,
BackboneFast, and BPDU Guard.  I can't seem to find CatOS commands to
configure these, although it's easy enough to find the commands for
doing them with Cisco STP.

Does Cisco's CatOS implementation of 802.1w have these features and
I'm just not finding the right documentation?

Do they exist, as part of the 802.1w implementation, only in the IOS
switching release for the 6500?

Are they not implemented in either, implying I must run CatOS Cisco
STP (PVST, etc.) to get the functionality along with flexibility in
assigning VLANs to a smaller set of spanning trees?
