Field Description
IPv6 Statistics
IPv6 received
total received The total number of input datagrams received by the interface,
including those received in error.
header errors The number of input datagrams discarded due to errors in their IPv6
headers, including version number mismatch, other format errors, hop
count exceeded, IPv6 options, etc.
too big errors The number of input datagrams that could not be forwarded because
their size exceeded the link MTU of outgoing interface.
no routes The number of input datagrams discarded because no route could be
found to transmit them to their destination.
address errors The number of input datagrams 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).
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.
unknown protocols The number of locally-addressed datagrams received successfully but
discarded because of an unknown or unsupported protocol. 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.
truncated packets The number of input datagrams discarded because datagram frame
didn't carry enough data.
discards The number of input IPv6 datagrams for which no problems were
encountered to prevent their continued processing, but which were
discarded (e.g., for lack of buffer space). Note that this counter does not
include any datagrams discarded while awaiting re-assembly.
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.
