If the switches are Cisco, then Cisco Works has a L2 STP forwarding path graphical display which can be used in cases where the L3 path is a logical abstraction overlaid on the underlying L2 topology. -----Original Message----- From: Larry Sheldon [mailto:LarrySheldon@cox.net] Sent: Wednesday, October 15, 2008 11:49 AM Cc: NANOG list Subject: Re: Network topology [Solved] Colin Alston wrote:
Maybe there should be something (I mean like, someone should come up with a standard :P) to trace switches in a path... Problem is I think even then the simple devices won't bother to support it.
I have been away from it for ma while and in truth don't know the answer--but-- To the best of my knowledge, "Layer two Switches" in fact operate as multi-port bridges. If that is true, then they ought to be transmitting BDUs which should be detectable and used for mapping. If the switches are all from the same manufacturer, there is a chance that the manufacture has a proprietary mapping tool. -- Requiescas in pace o email Two identifying characteristics of System Administrators: Ex turpi causa non oritur actio Infallibility, and the ability to learn from their mistakes.
