7.8.4.2 Confirmation of statistical information related to NAT-PT
The translation in NAT-PT may fail when the counters for "Non-translated packets"
and "Discarded packets" increase using a show ipv6 natpt statistics command.
Examine the possible cause in steps Subsection 7.8.4.4, “Confirmation of Log
Information (Factor Analysis)”-Subsection 7.8.4.5, “Confirmation of Binding Entry
(Factor Analysis)”. An error may exist in the setting of an NAT-PT interface when no
counters increase. Confirm the contents of the setting in step Subsection 7.8.4.3,
“Confirmation of Configuration Definition NAT Interface”.
7.8.4.3 Confirmation of Configuration Definition NAT Interface
NAT-PT performs no translation when an error exists in the interface name set using
a configuration definition command (CLI type 1) (natpt interface). Confirm the
contents of the configuration definition using a configuration definition command
(CLI type 1) (show natpt interface).
7.8.4.4 Confirmation of Log Information (Factor Analysis)
Confirm the log information using the show ipv6 natpt log command.
A log becomes Fail6->Fail4 when the translation from an IPv6 packet to an IPv4
packet fails. A log becomes Fail4->Fail6 when the translation from an IPv4 packet to
an IPv6 packet fails. The reason for each failure is displayed in detail.
Number other than zero indicates NAT
conversion failure.
