This read-create INTEGER specifies the target interface that matched traffic gets redirected or copied to, when rlQosClassMapRedirectAction is set to redirect-to-interface, analyzer-port, or multiple-interfaces mode. An admin fills this in only after choosing a redirect action that requires a destination, pointing at the specific port that should receive the redirected or mirrored copy of matched traffic. For example, when mirroring suspicious traffic to a packet analyzer, the admin sets this field to the interface number where the analysis tool's capture port is physically connected.
