Received Datagrams Discarded
Due To No Route
The number of input datagrams discarded because no route could be
found to transmit them to their destination
Received Datagrams With Unknown
Protocol
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 the input interface for some of the datagrams.
Received Datagrams Discarded
Due To Invalid Address
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 (for example, ::0) and
unsupported addresses (such as addresses with unallocated prefixes).For
entities that 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 Dut
To Truncated Data
The number of input datagrams discarded because datagram frame didn't
carry enough data.
Received Datagrams Discarded
Other
The number of input IPv6 datagrams for which no problems were
encountered to prevent their continued processing, but that were
discarded for reasons such as lack of buffer space. This counter does not
include any datagrams discarded while awaiting re-assembly.
Received Datagrams Reassembly
Required
The number of IPv6 fragments received that needed to be reassembled at
this interface. This counter is incremented at the interface to which these
fragments were addressed, which might not be the input interface for
some of the fragments.
Datagrams Successfully
Reassembled
The number of IPv6 datagrams successfully reassembled. 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.
Datagrams Failed To Reassemble The number of failures detected by the IPv6 reassembly algorithm (for
whatever reason: timed out, errors, and so on). 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
the input interface for some of the fragments.
Datagrams Forwarded The number of output datagrams that this entity received and forwarded to
their final destinations. In entities that do not act as IPv6 routers, this
counter includes only those packets that were source-routed through this
entity, and the source-route processing was successful. For a successfully
forwarded datagram the counter of the outgoing interface is incremented.
Datagrams Locally Transmitted The number of datagrams that this entity successfully transmitted from
this output interface.
Datagrams Transmit Failed The number of datagrams that this entity failed to transmit successfully.
Datagrams Successfully
Fragmented
The number of IPv6 datagrams that were fragmented at this output
interface.
