ND reachable time Neighbor reachable time
ND retransmit interval Interval for retransmitting a neighbor solicitation (NS) message
Hosts use stateless autoconfig for
addresses
Hosts use stateless autoconfiguration mode to acquire IPv6 addresses
InReceives
All IPv6 packets received by the interface, including all types of error
packets.
InTooShorts
Received IPv6 packets that are too short, with a length less than 40
bytes, for example.
InTruncatedPkts
Received IPv6 packets with a length less than that specified in the
packets
InHopLimitExceeds Received IPv6 packets with a hop count exceeding the limit
InBadHeaders Received IPv6 packets with bad basic headers
InBadOptions Received IPv6 packets with bad extension headers
ReasmReqds Received IPv6 fragments
ReasmOKs Received, reassembled IPv6 packets rather than IPv6 fragments
InFragDrops IPv6 fragments discarded due to certain error
InFragTimeouts
IPv6 fragments discarded because the interval for which they had
stayed in the system buffer exceeded the specified period
OutFragFails Packets failed in fragmentation on the outbound interface
InUnknownProtos Received IPv6 packets with unknown or unsupported protocol types
InDelivers
Received IPv6 packets that were delivered to application layer
protocols (such as ICMPv6, TCP, and UDP)
OutRequests Local IPv6 packets sent by IPv6 application protocols
OutForwDatagrams Packets forwarded by the outbound interface.
InNoRoutes
IPv6 packets that were discarded because no matched route can be
found
InTooBigErrors IPv6 packets that were discarded because they exceeded the PMTU
OutFragOKs Packets that were fragmented on the outbound interface
OutFragCreates
Number of packet fragments after fragmentation on the outbound
interface
InMcastPkts IPv6 multicast packets received on the interface
InMcastNotMembers
Incoming IPv6 multicast packets that were discarded because the
interface did not belong to the corresponding multicast groups
OutMcastPkts IPv6 multicast packets sent by the interface
InAddrErrors IPv6 packets that were discarded due to invalid destination addresses
InDiscards
