[nsp] Choice of CatOs on 4006 with WS-X4013 with Rapid PVST+ func tionality

[WATTIER Denis]

Hello,

I search the most stable version for CatOs on 4006 with Ws-X4013 including
RPVST+ functionality.
I have found the 8.1.2 version. Is it stable ?
I have to insert > 7.5.1 version (in order to have RPVST+).
All feedbacks are welcome.

Thank You.
