I am using net-snmp tool in linux based device. It has support for all(v1, v2c and v3) snmp versions. To test SNMP v3 traps, I have configured SHA as authentication protocol and AES(AES128) as a privacy protocol on my device. To receive trap on solarwind I have tried to add node for device but solarwind is not detecting node and giving "device is currently down, unreachable or provided credentials are not valid." error message. Before adding node there is option to test connection and in that test I am getting "Test successful" result and then after by clicking on next button I am getting this issue.
With MD5 as authentication protocol and DES as privacy protocol, I can successfully add node and get trap signals on solarwind trap window. But above configuration is not working.
Can you please suggest possible reasons behind this issue or the way I can debug this node detection issue?
