IPv6 Interface

– 1421 –

reassembly 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.

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 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.
