Object
notification
This notification is triggered when a duplicate IPv6
address assignment is detected. This notification is
generated if a client sends a Decline message. The DHCPv6
client is required to do Duplicate Address Detection (DAD)
before using the address and therefore would send the
Decline message if it found that the address was in use.
The DHCP server marks the IP address as unavailable for
leasing to clients. cnrdhcpv6DupIpv6Address indicates the
IPv6 address that triggered this event, cnrdhcpv6ClientId
and cnrdhcpv6ClientLookupKey indicate the client identifier
option and lookup key for the client that triggered this
event and cnrdhcpv6DupIpv6AddressDetectedBy object
indicates whether the client or server detected this
condition.
