6. From the Interface list, select the interface.
When the selection is changed, a page refresh occurs, causing all fields to be updated for
the newly selected port.

The following table describes the nonconfigurable information that is displayed.
Table 112. IPv6 Advanced Interface Statistics
Field Description
Total Datagrams Received The total number of input datagrams received by the interface, including
those received in error.
Received Datagrams Locally
Delivered
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
the input interface for some of the datagrams.
Received Datagrams Discarded
Due
T
o 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, errors discovered in processing their IPv6 options, and
so on
Received Datagrams Discarded
Due T
o
MTU
The number of input datagrams that could not be forwarded because their
size exceeded the link MTU of outgoing interface.
Received Datagrams Discarded
Due T
o No Route
The number of input datagrams discarded because no route could be
found to transmit them to their destination
Received Datagrams With Unknown
Protocol
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 the input interface for some of the datagrams.
Received Datagrams Discarded
Due T
o
Invalid Address
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 (for example, ::0) and
unsupported addresses (such as addresses with unallocated prefixes).For
entities that are not IPv6 routers and therefore do not forward datagrams,
this counter includes datagrams discarded because the destination
address was not a local address.
Received Datagrams Discarded Dut
T
o T
runcated Data
The number of input datagrams discarded because datagram frame didn't
carry enough data.
Received Datagrams Discarded
Other
The number of input IPv6 datagrams for which no problems were
encountered to prevent their continued processing, but that were
discarded for reasons such as lack of buffer space.
This counter does not
include any datagrams discarded while awaiting re-assembly.
Received Datagrams Reassembly
Required
The number of IPv6 fragments received that needed to be reassembled at
this interface.
This counter is incremented at the interface to which these
fragments were addressed, which might not be the input interface for
some of the fragments.
