I'm looking for a network mapping tool that can effectively identify devices connected to each port, ideally at both Layer 2 and Layer 3. I've been trying out Domotz, but while it creates a nice topology, the exported data doesn't provide the details I need. Has anyone found a better tool that has useful export options?

On the Layer 2 side, enabling LLDP on your systems could provide mapping information. For a smaller network, you can collect this data, dump it into Excel, and then import it into a tool like draw.io to visualize it better.
Lansweeper is a solid choice for this! It has capabilities for scanning and mapping out which devices are connected to specific ports on your network. Just make sure to set up SNMP on your switches so they can communicate with Lansweeper properly.
Totally! Just remember to enable SNMP on your switches for it to work its magic.
If your switches support it, you could also use DHCP Option 82 insertion. This allows you to capture port numbers in your DHCP logs along with MAC/IP addresses and possibly hostnames, which can be really helpful for mapping.
Hey there! I'm part of the Domotz team. You can actually export the Network Topology Mapping for further editing in Visio. We've also rolled out some updates to improve the topology features. If you're facing specific issues, let me know, and I'll see how we can assist. We also have a community over at Domotz for more tips and support!
Absolutely! Lansweeper does a great job, and I can confirm it really helps in identifying port connections.
