SNMP devices are incorrectly classified as routers or switches in ServiceNow, causing incorrect network device classification. Wireless components are a good example.
When ServiceNow Discovery determines that an active endpoint is an SNMP-enabled device, it will try to classify the device. The two primary classifications are routers and switches. However, other network classifications could be targeted: wireless controllers, access points, UPSs, VoIP phones, etc.
If the SNMP Object Identifier (OID) is not populated in ServiceNow, the system may perform a “best guess” device classification, causing data confusion and inaccuracies.
To avoid network device confusion, perform the following steps:
- Add the appropriate entries to the SNMP OID Classification table.
- For added details specific to a particular class/model, create both a new SNMP classification and discovery pattern.
