<![CDATA[Duplicate node detection vs. DNS?]]>Enabled server flags:
EnableZoning 1
UseDNSNameForDiscoveredNodes 1
SyncNodeNamesWithDNS 1
NetworkDiscovery.EnableParallelProcessing 1

Behavior:
SNMP-capable devices with multiple IP addresses in discovery networks are discovered multiple times. What we want is for the first discovered IP to be the primary host name.
Reverse DNS for each IP is unique.
For example,
ip1.node.some.domain <- primary, wanted
ip2.node.some.domain <- not wanted
ip3.node.some.domain <- not wanted

Shouldn't sysOID duplicate detection prevent the creation of duplicate nodes?

For some reason I had thought that it was enabled by default. Will let you know if we still have issues.

currently you should enable duplicate detection - that will not prevent duplicate node creation, but they will be deleted shortly after. We are currently working on improving parallel discovery and earlier duplicate detection.

Best regards,
Victor
