Hi guys
I like to add some oids like as Switch voltage in my database (I have mysql in centos and SNMP service) when I print oid in system heals just I get two oid for cpu-temperature and power-consumption but they are not work in linux snmpwalk also I research on internet and find other Oids for voltage in mikrotik PoE Switches like this "psu1-state: .1.3.6.1.4.1.14988.1.1.3.15.0" but unfortiunetly this oid isn't work in snmpwalk

Please advice me to read the correct volage from Mikrotik Switch PoE by SNMP v2
Thanks in advance
