Management protocols such as SNMP provide a reliable means to access device manangement information. Most role definitions check or test for the presence of:

  • Enterprise part. Identifies the manufacturer as indicated by the enterprise object identifier (OID) authorized by IANA.
  • Module identifier. Identifies the SNMPv2 MIB module to be accessed.
Tip: If the default role/sub role you picked to clone is a good starting point, in most cases you can re-use the module identifier (and scan rules using them)

The following example illustrates how to edit the enterprise part of an OID to return information for Liebert devices (lcUpsIdentManufacturer=476) rather than APC (lcUpsIdentManufacturer=318) UPS devices.
