IPv6 Interface
– 876 –
delivers The total number of datagrams successfully delivered to IPv6 user-
protocols (including ICMP). This counter is incremented at the interface
to which these datagrams were addressed which might not be
necessarily the input interface for some of the datagrams.
reassembly request
datagrams
The number of IPv6 fragments received which needed to be
reassembled at this interface. Note that this counter is incremented at
the interface to which these fragments were addressed which might
not be necessarily the input interface for some of the fragments.
reassembly succeeded The number of IPv6 datagrams successfully reassembled. Note that this
counter is incremented at the interface to which these datagrams were
addressed which might not be necessarily the input interface for some
of the fragments.
reassembly failed The number of failures detected by the IPv6 re-assembly algorithm (for
whatever reason: timed out, errors, etc.). Note that this is not necessarily
a count of discarded IPv6 fragments since some algorithms (notably
the algorithm in RFC 815) can lose track of the number of fragments by
combining them as they are received. This counter is incremented at
the interface to which these fragments were addressed which might
not be necessarily the input interface for some of the fragments.
IPv6 sent
forwards datagrams The number of output datagrams which this entity received and
forwarded to their final destinations. In entities which do not act as IPv6
routers, this counter will include only those packets which were Source-
Routed via this entity, and the Source-Route processing was successful.
Note that for a successfully forwarded datagram the counter of the
outgoing interface is incremented.
requests The total number of IPv6 datagrams which local IPv6 user-protocols
(including ICMP) supplied to IPv6 in requests for transmission. Note
that this counter does not include any datagrams counted in
ipv6IfStatsOutForwDatagrams.
discards The number of output IPv6 datagrams for which no problem was
encountered to prevent their transmission to their destination, but
which were discarded (e.g., for lack of buffer space). Note that this
counter would include datagrams counted in
ipv6IfStatsOutForwDatagrams if any such packets met this
(discretionary) discard criterion.
no routes The number of input datagrams discarded because no route could be
found to transmit them to their destination.
generated fragments The number of output datagram fragments that have been generated
as a result of fragmentation at this output interface.
fragment succeeded The number of IPv6 datagrams that have been successfully fragmented
at this output interface.
fragment failed The number of IPv6 datagrams that have been discarded because they
needed to be fragmented at this output interface but could not be.
ICMPv6 Statistics
ICMPv6 received
input The total number of ICMP messages received by the interface which
includes all those counted by ipv6IfIcmpInErrors. Note that this
interface is the interface to which the ICMP messages were addressed
which may not be necessarily the input interface for the messages.
errors The number of ICMP messages which the interface received but
determined as having ICMP-specific errors (bad ICMP checksums, bad
length, etc.).
