Summary
A duplicate IP address is detected for a vmknic interface configuration. This impacts IPv4 and IPv6.
Example
If 192.168.3.1 is the IP address used by the remote interface 00:50:56:76:b9:ae, the following event will be seen when this very same IP address is being assigned to the local vmknic interface vmk2.
Duplicate IP address detected for 192.168.3.1 on interface vmk2, current owner being 00:50:56:76:b9:ae
Impact
Any services that rely on the misconfigured interface might be affected by IP network connectivity issues. For example, if the interface on which the duplicate IP address is detected is on the vMotion NIC, then vMotion attempts might fail.
