Issue
Duplicate switch and router records are being created when a discovery schedule is running, resulting in misidentified existing configuration items (CI).
Release
Any release
Cause
Configuration item (CI) reclassification—changing between a router and a switch—can lead to duplicates when:
- The Identification Reconciliation Engine receives two simultaneous payloads from discovery with same name for IP Switch and IP Router.
When this happens:
- The existing record is deleted and a new one is inserted with the same sys ID, but a second payload may arrive during this process.
- The second payload cannot match on name, resulting in a duplicate record being created.
Resolution
To prevent misclassification between routers and switches:
- Ensure the system OID (object ID) is included in the SNMP - Classify probe payload.
- Under Standard Network Switch and Standard Network Router classification, make sure that sysoid does not equal an empty value.
