I wrote a perl/libgd tool some time ago which acts as a cgi script and takes live data and makes pretty pictures of it (per vlan). Note due a bunch of stuff not being uniformly implemented in IOS via SNMP I've had to screen scrape a little and I'm afraid this means I don't have any CatOS support.
Let me know offlist if you are interested in the code.
I have something to do this as well, using perl to grab all the details via SNMP, and then visualization using GraphViz. You're welcome to use it to start with: http://net.doit.wisc.edu/~plonka/stpgraph/ There's a sample PDF in the "examples/" sub-dir. Dave P.S. I know initially you request a "good tool", which is in the eye of the beholder. This one will want a programmer's eye, I guess. -- plonka@cs.wisc.edu http://net.doit.wisc.edu/~plonka/ Madison, WI
