IPv6 Interface
29
reassembly 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 sent
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.
generated fragments The number of output datagram fragments that have been generated as a result of
fragmentation at this output interface.
fragment succeeded The number of IPv6 datagrams that have been successfully fragmented at this
output interface.
fragment failed The number of IPv6 datagrams that have been discarded because they needed to
be fragmented at this output interface but could not be.
ICMPv6 Statistics
ICMPv6 received
input The total number of ICMP messages received by the interface which includes all
those counted by ipv6IfIcmpInErrors. Note that this interface is the interface to
which the ICMP messages were addressed which may not be necessarily the input
interface for the messages.
errors The number of ICMP messages which the interface received but determined as
having ICMP-specific errors (bad ICMP check sums, bad length, etc.).
destination unreachable
messages The number of ICMP Destination Unreachable messages received by the interface.
packet too big messages The number of ICMP Packet Too Big messages received by the interface.
time exceeded messages The number of ICMP Time Exceeded messages received by the interface.
parameter problem
message The number of ICMP Parameter Problem messages received by the interface.
echo request messages The number of ICMP Echo (request) messages received by the interface.
echo reply messages The number of ICMP Echo Reply messages received by the interface.
