not sure what u call the labelling, but below u can see "3 tools" and then
3.1 and 3.2 etc. I want to change 3.3 to the higher level label (like 3, but
in this case 4, and update the number going forward).

Two that will be discussed here are the Gigavue-420 from Gigamon and the
NetOptics Director. (The NetOptics products are also re-branded be Netscout.)
