Hi, I am trying to use snmp4sdn. I am able to have it read the database file and when I run the topology discovery. It says that the topology discovery is done. But how can I read it? where is it stored? is there a REST endpoint that I can use to read it with a GET ? Thank you for your help

You can see the flows of SNMP messages in wireshark. With topology Discovery command, the controller will ask for lldpLocChassisId and lldpLocPortId. These "GET" messages will be seen in wireshark. I am working on the same. Do tell me if you get anything or have some doubts.

Hi, I assume that opendaylight processes the SNMP messages and builds a map of the connectivity. Something like: device A on port X is connected to device B on port Y. I am looking for this data, because it is available somewhere. Are you able to build the same by parsing SNMP messages yourself?
