Layer 2 network map

Votes:

0

Does PRTG have an automatic method for making layer 2 network maps? I'm not a networking guy so I may be using the wrong terminology but what I'm looking for is a map/diagram that show the following:

Scenario 1 24 port switch 1 8 port switch

I want to know what physical port on the switches has them connected together and ideally automatically mapped for me. I mostly have manged Cisco switches but also some manged HP ones as well. If it could find unmanaged switches that sometimes get installed under a users desk that would be nice too.

Unfortunately PRTG has no way of knowing which switch is connected to which so creating an automatic graph is not possible. To create a graph with linked devices you would have to create the devices and link them manually and it's not possible to show which ports connect to the two devices unless you have a connector between the 2 port objects that you know they are connected with.

Unmanaged switches cannot really be discovered by PRTG since most of them don't have an IP address and you cannot ping them directly which is how PRTG finds devices on the network. Sorry I couldn't be of more help.

Thanks for the quick response. Are there any plans for such a feature and if estimated release date? I would think that PRTG is collecting so much data already that this wouldn't be too much more to implement.

Apologize for commenting on an older topic; but if you are looking for Layer-2 mapping for PRTG you can take a look at UVexplorer (www.uvexplorer.com) with PRTG integration.

UVexplorer will perform full network discovery and then allow for export devices and maps to PRTG. UVexplorer allows for exporting of maps to Microsoft Visio, SVG or PDF formats.

UVexplorer also supports scheduled discoveries to ensure that your PRTG maps are always "up-to-date".

Hope this helps.
