Solution: Addressed in versions 8.7.0, 8.6.2 and 8.5.4
To diagnose, run the following command in Control Server CLI:
Device –ip <ipAddr> -dumpPW Bradford
Device –ip <ipAddr> -dumpPW Bradford
Look for the entry Name = SNMP_VERSION_ATTR value = null in the output:
Landscape = 345049899844 00:50:56:93:A3:44
Pollable = true, Poll interval = 10 Minutes
Type = 1.3.6.1.4.1.9.1.2170

Description = Cisco Controller
IP = 172.24.0.20
State = Active

Workaround: Run the following command from the CLI :
Device -ip <ipAddr> -delAttr -name SNMP_VERSION_ATTR
