Running USM Discovery Wizard to discover some network devices (routers) using SNMP V3 but the devices are not getting discovered.
discovery_agent logs at log level 5 showed the following messages:
May 30 21:21:29:375 [DiscoveryRun, discovery_agent] 2 duplicate SNMPv3 EngineIDs
Note that some duplicates may be the result of the discovery IP scopes including multiple IP addresses for the same device.
This is followed by the EngineID and the ip addresses of the devices that are attempting to use the same engine id.
Note: SNMP V2 and V1 will still discover the devices as the EngineID is only used for V3.
