This is probably not the most important thing in the world - I have recently taken over as admin of a medium/small network (40+ switches) - and I found CNA (Cisco Network Assistant, latest version at this time, 5.6) to be a good quick tool to get an overview and grab all the configs etc.
I find it helpful to turn on the topolofy options for showing vlans in color (colored edg of the green fat line). But, it only seems to show either a single color for lines off of access ports, or it shows all the colors in sequence of full trunk lines.
If a trunk has "switchport trunk allowed vlan 1,2,4,8" or similar set, it shows no vlan's at all on that link.
(VTP is configured, and CDP is enabled everywhere, if that matters).
if there was a way to maker CNA show what vlans are really being allowed it would be a neat tool to help make sure I didnt forget something..
