When running Pattern based Discovery, if ECC payload is splitted (ECC queue MultiPaged), Discovery can create redundant entries in Discovery Status > Devices tab, as showing in the screenshot below:
Then in Discovery > Home, it shows these device entries as Unidentified IPs.
Steps to Reproduce
Run Pattern based discovery to a device that returns large payload (e.g. a switch with multiple VLANs), issue happens if the payload is splitted.
There is no known workaround for this issue. If you are able to upgrade, review the "Intended Fix Version" section below below to determine the versions that have a permanent fix.
