output definitions
Total Total number of input packets received, including those received in
error.
Header errors Number of input packets discarded due to errors in their IPv6
headers (e.g., version number mismatch, other format errors, hop
count exceeded, errors discovered in processing their IPv6 options).
Too big Number of input packets that could not be forwarded because their
size exceeded the link MTU of the outgoing interface.
No route Number of input packets discarded because no route could be
found to transmit them to their destination.
Address errors Number of input packets discarded because the IPv6 address in
their IPv6 header's destination field was not a valid address to be
received at this entity. This count includes invalid addresses (e.g., ::0)
and unsupported addresses (e.g., addresses with unallocated prefixes).
Unknown protocol Number of locally-addressed packets received successfully but dis-
carded because of an unknown or unsupported protocol.
Truncated packets Number of input packets discarded because the packet frame
did not carry enough data.
Local discards Number of input IPv6 packets for which no problems were encountered
to prevent their continued processing, ut which were discarded (e.g., for
lack of buffer space). Note that this counter does not include any pack-
ets discarded while awaiting re-assembly.
Delivered to users Total number of packets successfully delivered to IPv6 user protocols
(including ICMP).
Reassembly needed Number of IPv6 fragments received that needed to be reassembled.
Reassembled Number of IPv6 packets successfully reassembled.
Reassembly failed Number of failures detected by the IPv6 reassembly algorithm (for
whatever reason: timed out, errors, etc.).
Multicast packets Number of multicast packets received.
Forwarded Number of output packets that this entity received and forwarded to
their final destinations.
Generated Total number of IPv6 packets that local IPv6 user-protocols (including
ICMP) supplied to IPv6 in requests for transmission. Note that
this counter does not include any packets counted by the Forwarded
statistic.
Local discards Number of output IPv6 packets for which no problem was encountered
to prevent their transmission to their destination, but were discarded
(e.g., for lack of buffer space). Note that this counter would include
packets counted by the Forwarded statistic if any such packets met this
(discretionary) discard criterion.
Fragmented Number of IPv6 packets successfully fragmented.
Fragmentation failed Number of IPv6 packets discarded because they needed to be frag-
mented but could not be.
Fragments generated Number of output packet fragments generated as a result of fragmenta-
tion.
Multicast packets Number of multicast packets transmitted.
