Received Datagrams Discarded Due To MTU - The number of input datagrams that
could not be forwarded because their size exceeded the link MTU of outgoing interface.
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 necessarily 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
(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.
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 which were
discarded (e.g., for lack of buffer space). Note that this counter does not include any
datagrams discarded while awaiting re-assembly.
Received Datagrams Reassembly Required - 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.
Datagrams Successfully Reassembled - 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.
Datagrams Failed To Reassemble - The 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 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.
Datagrams Forwarded - The 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 is incremented.
