Setting the Switch’s IP Address (IP Version 6)
– 457 –
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 increment
ed at the interface to which these fragments were addressed
which might not be necessarily the input interface for some of the
fragments.
Reassembled 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.
Reassembled 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.
IPv6 Transmitted
Forwards Datagrams 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.”
Requests The total number of IPv6 datagrams which local IPv6 user-
protocols (including ICMP) supplied to IPv6 in requests for
transmission. Note that this counter does not include any
datagrams counted in ipv6IfStatsOutForwDatagrams.
Discards The number of output IPv6 datagrams for which no problem was
encountered to prevent their transmission to their destination, but
which were discarded (e.g., for lack of buffer space). Note that
this counter would include datagrams counted in
ipv6IfStatsOutForwDatagrams if any such packets met this
(discretionary) discard criterion.
No Routes The number of input datagrams discarded because no route could
be found to transmit them to their destination.
