Dude doesn't show interfaces on SNMP

Hello All!
I have problem with my devices (UniFI Switch).
Dude doesn’t show interfaces on SNMP protocol. SNMP set up correctly but list interfaces are empty.
Can anybody have idea ?

The problem was solved. You need set up SNMPv2 in the setting the DUDE, after that you can see interfaces with SNMP protocol.
