Ports needed for discovery

[Santiago Ruales]

Hi everyone

Please can you tell me the necessary ports that should be considered only for discovery (not for service mapping)?

Thanks

Hello,

Have you looked at this posting?

Take note of the dynamic port ranages mentioned at the end.

It depends on the devices in your environment. If you are going to discover only Windows and Linux devices then Port 135 (Windows) and 22 (Linux) enough. You need to open more ports based on the devices you are planning to discover.

You can refer the below document to know about the other ports:
