Confirmation of interface state and routing state

Ver. 07-02
Figure 5-65 Example of display of NAT-PT statistical information
The statistical information on DNS query or DNS response translation is
displayed using DNS-ALG if a show dns-relay command is executed when a
NAT-PT function is used. The number of translation times increases when the
name resolution for which DNS-ALG of the router is used succeeds.

(b) Confirmation of binding entry
The binding entry is displayed when a show ipv6 natpt translation command is
executed. The address, port number, layer 4 protocol, or TCP status (for TCP)
between terminals that perform communication can be confirmed from the
binding entry. If no communication can be performed, display a binding entry
and confirm whether the binding entry between terminals that try to perform
communication is created.
Figure 5-67 Binding entry display
(c) Confirmation of log
The log of the failure in translation or the change history of a binding entry is
displayed when a show ivp6 natpt log command is executed. As the confirmation
result of statistical information or a binding entry, detailed information can be
obtained from the log when it is considered that translation has not been
performed normally.
