Automatic Network Diagram Topology Software

[superfly611]

I'm looking for software that will automatically detect the routers/switches printers and computers and whatever else I may have on my network. I know you could use Microsoft Visio to draw one yourself but I believe there was a program like Cisco magic network or something like that that would draw it automatically. I have probably five wireless computers as well as wired. I have 2 synology ds1513+ NAS. It goes from my main router to a switch and another switch on a long run out to the solar panels and workshop area. I really would just like it to be in a nice diagram with the actual model and whatever info it may provide so I could explain it to other people working on it. Is there such a software that Does this automatically? If so is there any free versions and if not I'm not looking to spend hundreds of dollars just to do this. $50 or so if not all possible.

Any feedback would be much appreciated.

I know there are enterprise appliances that do this such as Redseal, but I don't know of a way of doing it yourself without just doing an nmap and making a diagram yourself. If you're looking for cheap that's probably the way to go.

I am sure there are enterprise stuff that will do this, at enterprise prices, and even that, not perfect. $50? DIY.

Correct, there is a whole lot of configuration and industry-specific knowledge that goes into configuring such appliances (not to mention ungodly cost). Usually these are implemented for... well... enterprises. 1000+ assets that need tracking etc.

OP - if you only have < 10 devices there is no reason that managing / diagramming them manually should be difficult.

Unless the last guy quit, leaving no doc or passwords and your boss just plucked you from accounting to "take care of it" 😀

You have to remember I can put a bunch of unmanged switches in a network and no software tool can find them. They are completely transparent. Almost every tool that does this uses feature in the equipment to help map things out. SNMP tends to be the one of the most common but even then it only works on some of the better known brands of equipment that document their mibs.

Really old versions of visio used to have a basic network scanner but microsoft removed this.

In a home network the software will assume 1 switch with all the devices it can find connected to it. It generally will just show boxes because it has no what to know what a IP represents because again it would have to have snmp configured so the software could identify the device
