Beispiel
Den Messwert für das Systeme-Element mit ID=201002 abrufen:
$ snmpget -v2c -cread 192.168.0.193 DIDACTUM-SYSTEM-MIB::ctlUnitElementValue.201002
oder ohne MIB-Datei
$ snmpget -v2c -cread 192.168.0.193 .1.3.6.1.4.1.39052.1.3.1.7.201002
Beispiel
Den Namen des Elements mit ID=102003 ändern:
$ snmpset -v2c -cwrite 192.168.0.193 DIDACTUM-SYSTEM-MIB::ctlUnitElementName.102003 s "Dry sensor"
DIDACTUM-SYSTEM-MIB::ctlUnitElementName.102003 = STRING: "Dry sensor"
