Object
notification
deprecated
This notification is triggered when a duplicate IPv6 prefix
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
prefix and therefore would send the Decline message if it
found that the address was in use.
The DHCP server marks the prefix as unavailable for leasing
to clients. cnrdhcpv6DupPrefix and cnrdhcpv6DupPrefixLength
indicate the duplicate prefix and length 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.
