This object identifies the destination interface, a physical port or port-channel, that receives the mirrored packets for this monitoring session. An admin points this at the port where a packet analyzer or IDS is connected so all captured traffic from the session's source ports or VLANs is delivered there; a value of zero means no destination interface is currently associated with the session. An admin plugging a sniffer into port 24 would set dPktMonSessionDestInterface to that port's ifIndex so mirrored traffic from the monitored source ports is copied out to port 24.
