Sending Packets to a Mediation Device on MX, M and T Series Routers

Dynamic flow capture enables you to capture passively monitored packet flows on the basis of dynamic filtering criteria, using Dynamic Tasking Control Protocol (DTCP) requests. The flow-tap application extends the use of DTCP to intercept IPv4 packets in an active flow monitoring station and send a copy of packets that match filter criteria to one or more content destinations. Flow-tap data can be used for lawful intercept purposes and provides flexible trend analysis for detection of new security threats. The flow-tap application is supported on M Series and T Series routers, except M160 routers and TX Matrix platforms.
