Hello,
I'm trying to run discovery on Arista switch (DCS-7050SX-64). Upon running discovery, it found 28 neighbors and filled up the discovery_device_neighbors table accordingly but the Device Neighbors tab is still empty. Is there anything else needed to show the neighbors in the tab?
Regards,
Ty

It turns out that we need to turn the glide.discovery.bgp_router_disable property to false. By default, Discovery does not populate neighbors if the network switch's bgp is on (assuming that bgp-enabled switch has too many neighbors to make it valuable discovery item.) We turn on the bgp for most of network switches and switching off the property indeed fixed my issue.

Hey Hi @Ty Hahn & @Niklas Peterson ,
I have set the relevant discovery property to false, and as a result, I can now see neighbor devices attached to my router in the discovery_device_neighbors table.
I would like to understand the following:
Will ServiceNow automatically create Configuration Items (CIs) for these neighbor devices?
My requirement is to create CI records for the neighbor devices and establish relationships (links) between them and the parent router.
Is there a way to achieve this requirement in ServiceNow Discovery? If so, what would be the recommended approach?
Looking for your respose!
Thanks in Advance 🙂

Hi,
ServiceNow Discovery will not create the devices based on the neighbor information, they need to be discovered individually. If they then turn out to be neighbors then the discovery_device_neighbors table will connect them as neighbors.

Niklas
