Configuring Dynamic Translation and Translation Timeouts
Purpose
configured for the ip nat translation
sampling-timeout command expires.
Specifies the maximum number of dynamic NAT
translations. The number of entries can be between 1 and
1023.
The all-host keyword enforces this translation limit on all
hosts. The number of entries per host can be between 1
and 1023.
Specifies the timeout value for UDP-based dynamic NAT
entries.
• Dynamically created NAT translations are cleared
when the configured timeout limit is reached. All
configured timeouts are triggered after the timeout
configured for the ip nat translation
sampling-timeout command expires.
Specifies the timeout value for dynamic NAT translations.
Specifies the timeout value for TCP data packets that send
the SYN request, but do not receive a SYN-ACK reply.
The timeout value ranges from 1 second to 172800
seconds. The default value is 60 seconds.
The never keyword specifies that the SYN timer will not
be run.
Specifies the timeout value for the flow entries when a
connection is terminated by receiving finish (FIN) or reset
(RST) packets. Use the same keyword to configure the
behavior for both RST and FIN packets.
The timeout value ranges from 1 second to 172800
seconds. The default value is 60 seconds.
The never keyword specifies that the FIN or RST timer
will not be run.
Exits global configuration mode and returns to privileged
EXEC mode.
