snmp bug with firmware v6.39.2

I have a snmp bug with RB750GL and firmware v6.39.2 and routerboard firmaware 3.33

snmpget -c public -v 1 192.168.11.189 .1.3.6.1.4.1.14988.1.1.3.10.0
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: SNMPv2-SMI::enterprises.14988.1.1.3.10.0

Are you sure this is a bug? That behaviour is normal when you read a value that does not exist for
the specific device. I don’t know if the RB750GL does have a temperature sensor, several other
devices don’t.
