Ignition 8, Kymera SNMP driver- unable to get connected to SNMP devices

I installed Ignition 8, MODBUS module and Kymera SNMP module.
I am able to connect to MODBUS devices from Igntion, however, I am unable to connect any SNMP devices, although I use the correct MIB files.
Is there procedure to link Igntion and Kymera to SNMP devices? Can anyone help?
