The all parameter displays all of the configured static NAT64 IPv6-IPv4 address mappings.
Table 7 describes the fields returned by the show nat64 map command.
Displaying in-progress dynamic NAT64 mappings
Use the show nat64 dns-in-flight command to display in progress NAT64 DNS dynamic learning on
stateless NAT64 gateways.
Syntax: show nat64 dns-in-flight
Table 8 describes the fields returned by the show nat64 dns-in-flight command.
Clearing NAT64 information
You can clear the following information from a NAT64 configuration:
• Dynamic IPv4-IPv6 mappings
• NAT64 statistics
Clearing dynamic IPv4-IPv6 mappings
Use the clear nat64 dns-dynamic-mapping command to clear IPv4-IPv6 mappings learned through
DNS on a ServerIron ADX. This command is issued as follows:
ServerIron ADX# clear nat64 dns-dynamic-mapping 1.1.1.1 2001:db8:7000
Syntax: clear nat64 dns-dynamic-mapping { <IPv4_address> | <IPv6_address> | all }
The <IPv4_address> variable specifies the IPv4 address for the IPv6-IPv4 mapping that you want to
clear.
