Rather than SNMP probing, for larger layer3 networks try setting up a proper config archive (rancid), then build on mktop and top2dot: http://www.nanog.org/meetings/nanog26/presentations/stephen.pdf 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/ -- RSUC / GweepNet / Spunk / FnB / Usenix / SAGE / NewNOG
