IPv6 Interface
– 678 –
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 checksums, 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.
router solicit messages The number of ICMP Router Solicit messages received by the interface.
router advertisement
messages
The number of ICMP Router Advertisement messages received by the
interface.
neighbor solicit messages The number of ICMP Neighbor Solicit messages received by the
interface.
neighbor advertisement
messages
The number of ICMP Neighbor Advertisement messages received by
the interface.
redirect messages The number of Redirect messages received by the interface.
group membership query
messages
The number of ICMPv6 Group Membership Query messages received
by the interface.
group membership
response messages
The number of ICMPv6 Group Membership Response messages
received by the interface.
