How to discover non OpenFlow enabled switch using Opendaylight?

In my current network setup, I have a non OpenFlow enabled switch (Cisco Nexus 7k) and couple of other servers running Ubuntu 14.04. I installed Opendaylight (Base Edition Snapshot) and would like to discover the Cisco Nexus switch in Opendaylight either using POSTman (RESTful client) or through Web GUI. I am running ODL with OF1.3 like

./run.sh -of13

I tried using the Learning Switch application and was able to discover network entities created by Mininet only. How do I discover physical switches which are already existing in the network? Just pinging the switch from the ODL controller or the hosts created by Mininet does not help.

Opendaylight controller needs some mechanism / protocol to communicate with the said device. If the device supports any of the following protocol, then the current Opendaylight controller can detect it. - Openflow, NetConf, OVSDB, SNMP, BGP (there is some caveat here... need to clarify).

Can you check if your device (in this case Cisco Nexus 7k) supports any of these protocols ? And if yes, you can search for helpful articles in wiki.opendaylight.org for the relevant info for a given protocol. If you cannot find it, please reply to this answer and we will help you narrow down.

I think SNMP and BGP are supported on the Cisco Nexus 7k (I did not mention LLDP in my earlier post, how about using it?). So, now the question is how can I use SNMP for Topology discovery? Also, after posting this in controller-users forum, there was a bug filed. It is copied here for reference: https://bugs.opendaylight.org/show_bug.cgi?id=1563 Kindly point me to the right information from the Wiki

I think the SNMP4SDN project might tickle your interest : https://wiki.opendaylight.org/view/SNMP4SDN:Main
