Descriptions

ciscoNetRegDhcpv6DuplicatePrefix — Cisco, Cisco MIB copies (LibreNMS/Observium Community)

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.
