The -t primary option is used to indirectly query the current filter rules to determine whether a rule exists that applies to a particular kind of data traffic. Given a source and destination address, a protocol, and (if the protocol requires it) a source and destination port pair, all of the filter rules that apply to that kind of data traffic are displayed in the order in which they would be applied. The search can be further qualified by specifying whether the traffic is outbound or inbound by security class.
See The z/OS UNIX ipsec command IP traffic test (-t) option for parameter descriptions.
