How to set node dependencies

[victor]

Do those Ubiquity APs support LLDP?

Also, important part of topology-based correlation is ability of the server to find route from itself to managed devices. Try to select one of the Ubiquity APs, choose "route from" from context menu, and select node representing NetXMS server itself as source. Will it show complete IP path?

From what I can find they do not support LLDP, only CDP.

I tried "route from" and pointed to the server and got this result:

Can you also show screenshot of interfaces for tower's main router? Does it see APs as peer nodes?

As for "route from" NetXMS server - it shows 10.240.8.1 as the next hop, but looks like there's no corresponding node in NetXMS, that's why it can not continue.

I added the rest of the routers between the server and the tower and now "route from" works and knows the whole route back to the server.

The main tower routers still do not see the UBNT access points as peer nodes. I can't see any way to manually add them.

Could you please show capabilities for Ubuntu AP and adjacent router?

We currently does not have an option to configure L2 links manually, although we have this as feature request.

Can you be more specific about capabilities? The mikrotik does support LLDP but the UBNT AP does not. Is that what you are meaning?

[victor]

I mean what NetXMS shows on overview page for those nodes in "Capabilities" section - to check how server sees those devices.

Attached. Thanks

So the problem here is that AP in question does not support neither LLDP nor CDP (not even spanning tree), so there is no way of getting topology information from it. CDP/LLDP not being supported in this context only means that information collected via those protocols is not made available via SNMP, even if device can send/receive CDP or LLDP packets.
If there is topology information available through vendor MIBs, then we probably can implement topology information reading on driver level.

I believe after messing around with this for some time it is working. Once I added all nodes on the routes between the server and the nodes, did "route from" to the Netxms server, initial testing is showing dependencies working properly. Even on the UBNT ap's and other devices without SNMP. 

Big thank you to everyone who helped get me through this!
