The -o primary option is used to display the selected NAT traversal remote port translations. If no remote IP address is specified (using the -q option), all NAT traversal remote port translations are displayed. If there is a selected remote IP address (using the -q option), or a selected remote IP address with one or more ports (using the -q -u options), then the selected NAT traversal remote port translation information is displayed.
See The z/OS UNIX ipsec command NATT port translation (-o) option for parameter descriptions.
