IPv6 Statistics (continued)
Statistic
Description
AddrErrors
Number of datagrams discarded because the IP address in
their IP headerʹs destination field was not a valid address to
be received at this entity (the switch). This count includes
invalid addresses. For entities which are not IP Gateways
and therefore do not forward datagrams, this counter
includes datagrams discarded because the destination
address was not a local address.
FwdDgrams
Number of input datagrams for which this entity (the
switch) was not their final IP destination, as a result of which
an attempt was made to find a route to forward them to that
final destination. In entities which do not act as IP Gateways,
this counter will include only those packets, which were
Source‐Routed via this entity (the switch), and the Source‐
Route option processing was successful.
UnknownProtos
Number of locally addressed datagrams received
successfully but discarded because of an unknown or
unsupported protocol.
Discards
Number of IP datagrams for which no problems were
encountered to prevent their continued processing, but
which were discarded (for example, for lack of buffer space).
Note that this counter does not include any datagrams
discarded while awaiting re‐assembly.
Delivers
Number of datagrams successfully delivered to IP
user‐protocols (including ICMP).
OutRequests
Number of IP datagrams which local IP user‐protocols
(including ICMP) supplied to IP in requests for
transmission.
OutDiscards
Number of output IP datagrams for which no problem was
encountered to prevent their transmission to their
destination, but which were discarded (for example, for lack
of buffer space).
OutNoRoutes
Number of IP datagrams discarded because no route could
be found to transmit them to their destination. Note that this
includes any datagrams which a host cannot route because
all of its default gateways are down.
ReasmReqds
Number of IP fragments received which needed to be
reassembled at this entity (the switch).
ReasmOKs
Number of IP datagrams successfully re‐ assembled.
ReasmFails
Number of failures detected by the IP re‐ assembly
algorithm (for whatever reason: timed out, errors, and so
forth). Note that this is not necessarily a count of discarded
IP 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.
