IPv6 Interface
TABLE 148 show ipv6 traffic - display description
Field Description
IPv6 Statistics
IPv6 recived
total received The total number of input datagrams received by the interface, including those
received in error.
header errors The number of input datagrams discarded due to errors in their IPv6 headers,
including version number mismatch, other format errors, hop count exceeded, IPv6
options, etc.
too big errors The number of input datagrams that could not be forwarded because their size
exceeded the link MTU of outgoing interface.
no routes The number of input datagrams discarded because no route could be found to
transmit them to their destination.
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 incremented at the interface to which these
fragments were addressed which might not be necessarily the input interface for
some of the fragments.
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.
