ERROR

This message occurs when ONTAP receives unexpected Neighbor Discovery (ND) packets. The packets could come from various sources, but usually they come from a source IP address. The EMS message shows the information from the packet. If something specific is wrong, another EMS message with more information will display with this EMS message.

ONTAP received an invalid Neighbor Discovery (ND) packet. If the condition persists, check your network infrastructure, such as switches, routers, or other connected equipment.

nd6_ns_input: src=%s, dst=%s, tgt=%s.

srcIpAddress (STRING): Source IPv6 address.
dstIpAddress (STRING): Destination IPv6 address.
tgtIpAddress (STRING): Target IPv6 address.

INFORMATIONAL

This message occurs when the target address packet is found to be multicast.

(None).

INFORMATIONAL

This message occurs when the destination address packet is bad due to link-layer address option.

(None).

nd6_ns_input: Bad DAD packet (link-layer address option).

(None).

ALERT

This message occurs when Duplicate address Detection (DAD) for the specified interface address is completed, and the duplicate address is found.

The IP address is already in use by another system on the network. The system that is holding the IP address is identified by MAC address. Please ensure that the IP address you are trying to assign is not already assigned to another system.

%s: DAD complete for %s - duplicate found. %s is holding the IP address.

ifName (STRING): Interface name.
ip6address (STRING): IPv6 address that is found to be a duplicate.
ipHolderMac (STRING): MAC address of the device holding this IP.

INFORMATIONAL

This message occurs when Duplicate address Detection (DAD) ignores Neighbor Solicitation (NS) packet for the specified interface address.

(None).

nd6_dad_ns_input: Ignoring DAD NS packet for address %s(%s).

targetAddress (STRING): Printable that is loggable representation of target IPv6 address.
ifAddress (STRING): Interface address.

ALERT

This message occurs when Duplicated Address Detection (DAD) is started and memory allocated fails for the specified interface address.

(None).

ip6address (STRING): Printable that is a loggable representation of an IP6 address.
ifAddress (STRING): Interface address.

NOTICE

This message occurs during Duplicated Address Detection (DAD), when number of tries or count to transmit DAD packet exceeds the predefined maximum number of tries.

(None).

%s: could not run DAD, driver or link problem?

ifAddress (STRING): Interface address.

NOTICE

This message occurs when Duplicated Address Detection (DAD) timer is called, and the parameter passed to it, is a duplicated interface address.

(None).

nd6_dad_timer: Called with duplicated address %s(%s).

ip6address (STRING): Printable that is a loggable representation of an IP6 address.
ifAddress (STRING): Interface address.

NOTICE

This message occurs when Duplicated Address Detection (DAD) Timer is called with non tentative interface address.

(None).

nd6_dad_timer: Called with non-tentative address %s(%s).

ip6address (STRING): Printable that is a loggable representation of an IP6 address.
ifAddress (STRING): Interface address.

Deprecated as of Data ONTAP 9.8 since this EMS is no longer needed.

NOTICE

This message occurs when Duplicated Address Detection (DAD) timer is called and the interface address passed to it is NULL.

(None).

nd6_dad_timer: Called with null parameter.

(None).

ALERT

This message occurs when there is a duplicate target IP6 address.

(None).

nd6_na_input: Duplicate IP6 address %s.

targetAddress (STRING): Printable that is a loggable representation of target IP6 address.

INFORMATIONAL

This message occurs when there is duplicate source IP6 address.

(None).

nd6_ns_input: Duplicate IP6 address %s.

srcAddress (STRING): Printable that is a loggable representation of source IP6 address.

INFORMATIONAL

This message occurs because of invalid Neighbor Discovery (ND)option.

(None).

nd6_ns_input: Invalid ND option; ignored.

(None).

INFORMATIONAL

This message occurs because of an invalid Neighbour Discovery (ND) option during neighbor advertising input handling.

(None).

nd6_na_input: Invalid ND option; ignored.

(None).

NOTICE

This message occurs during Neighbor Advertising (NA)input handling, because of invalid target address.

(None).

nd6_na_input: Invalid target address %s.

targetAddress (STRING): Target IP6 address.

ERROR

This message occurs when 'dad_duplicated' is called and manual intervention is required.

(None).

%s: Manual intervention required.

ifAddress (STRING): Interface address.

INFORMATIONAL

This message occurs when there is a lladdrlen mismatch for the specified IP6 address.

(None).

nd6_ns_input: lladdrlen mismatch for %s (if %d, NS packet %d).

ip6address (STRING): Printable that is a loggable representation of an IP address.
ifAddrlen (INT): Interface address length.
lladdrlen (INT): Address length.

INFORMATIONAL

This message occurs during Neighbor Advertising (NA) input handling, when there is a lladdrlen mismatch for the specified IP6 address.

(None).
