nat64 position
Function
The nat64 position command configures a NAT64 flexible flow log or user log template.
The undo nat64 position command deletes a NAT64 flexible flow log or user log template.
By default, no NAT64 flexible flow log template is configured.
This command is supported only on the NetEngine 8000 F1A.
