How to enable SNMP in modules?

How to enable SNMP in modules? I’m trying to monitor APs and SMs but get no answer from them.
I’d tested a few different snmp utils, tried my actual “Accessing Subnet” and in a module configuration, connected the module to my pc directly but with no result.
The snmp permission is set to read only, no filtering is enabled in modules.

Anyone who uses NMS, how did you tune SNMP in your canopy modules?

Does NMS support SNMP v2? Canopy is SNMP v2 only
