There is also the possibility to create your own SNMP types - in case the predefined SNMP types are not sufficient.
Own SNMP types are created and managed in Inventory - SNMP - SNMP Base Types.
With the button New you can give the type a name as well as a German and English text. Furthermore, a value is needed. Here it is recommended to use an own number range, for example starting from 1000. However, this is not mandatory.
Afterwards a keyword can be assigned to this SNMP type.
