Rather than SNMP probing, for larger layer3 networks try setting up 
a proper config archive (rancid), then build on mktop and top2dot:

If you want to use SNMP and have good detail for layer2 networks and
edge stations, take a look at http://www.netdisco.org/
 
Good old intermapper has been commercial for a while, does probing 
using several methods and makes pretty maps http://www.intermapper.com/
