and unsupported addresses (for example, addresses with unallocated prefixes). For entities
which are not IPv6 routers and therefore do not forward datagrams, this counter includes
datagrams discarded because the destination address was not a local address.
Received Datagrams Discarded Due To Truncated Data:
Number of input datagrams
discarded because datagram frame didn't carry enough data.
Received Datagrams Discarded Other:
Number of input IPv6 datagrams for which no
problems were encountered to prevent their continue processing, but which were discarded
(e.g., for lack of buffer space). Note that this counter does not include datagrams discarded
while awaiting re-assembly.
Received Datagrams Reassembly Required:
Number of IPv6 fragments received which
needed to be reassembled at this interface. Note that this counter increments at the interface
to which these fragments were addressed, which might not be necessarily the input interface
for some of the fragments.
Datagrams Successfully Reassembled:
Number of IPv6 datagrams successfully
reassembled. Note that this counter increments at the interface to which these datagrams
were addressed, which might not be necessarily the input interface for some of the
fragments.
Datagrams Failed To Reassemble:
Number of failures detected by the IPv6 reassembly
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 by
combining them as they are received. This counter increments at the interface to which
these fragments were addressed, which might not be necessarily the input interface for
some of the fragmen
ts
Datagrams Forwarded:
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 increments.
Datagrams Locally Transmitted: 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.
Datagrams Transmit Failed:
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.
Fragments Created:
Number of output datagram fragments that have been generated as a
result of fragmentation at this output interface.
Datagrams Successfully Fragmented:
Number of IPv6 datagrams that have been
successfully fragmented at this output interface
Datagrams Failed To Fragment:
Number of IPv6 datagrams that have been discarded
because they needed to be fragmented at this output interface but could not be.
Multicast Datagrams Received:
Number of multicast packets received by the interface.
Multicast Datagrams Transmitted:
Number of multicast packets transmitted by the
interface.
Total ICMPv6 messages received:
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.
ICMPv6 Messages with errors:
Number of ICMP messages which the interface received
but determined as having ICMP-specific errors (bad ICMP checksums, bad length, etc.).
ICMPv6 Destination Unreachable Messages:
Number of ICMP Destination Unreachable
