Does Dynatrace maps devices discovered via SNMP extensions on the smartscape topology or service flow?  
Is any relation created between a network device and other entities?

Regards

Hi,

I have never tried it or explore it but looks like a use case for&nbsp;[Custom topology model](https://www.dynatrace.com/support/help/shortlink/topology-model).

Best regards

[@y\_buccellato](https://community.dynatrace.com/user/4804),

Topology is included in the SNMP v2 extensions from Dynatrace. Basically, it associates interfaces with the respective devices.

I have not seen yet relationships between a network device and other entities. It would be great if interfaces could de joined/related when they are part of o point-to-point link, as they are in dedicated network monitoring solutions, but most of the times this is done with proprietary solutions, that only work for devices of a certain vendor.

I did see at Perform that a lot of work is being done at the network level. And I believe incorporating this information into the Dynatrace topology model might be something that me be coming in the future…

[@AntonioSousa](https://community.dynatrace.com/user/17213)&nbsp;relations between entities created using the custom topology model (Extensions 2.0) and built-in entities are not yet present and AFAIK are being worked on. With Custom Devices (Legacy Extenions 1.0) the relations are created based on opaque services and based on IP addresses - a service created on top of the custom device.
