Field Description
IPv6 Statistics
IPv6 recived
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.
