Example: Flow-Tap Configuration on T and M Series Routers

The following example shows all the parts of a complete flow-tap configuration.


The following example applies only to M Series and T Series routers, except M160 and TX Matrix routers. For MX Series routers, because the flow-tap application resides in the Packet Forwarding Engine rather than a service PIC or Dense Port Concentrator (DPC), the Packet Forwarding Engine must send the packet to a tunnel logical (vt-) interface to encapsulate the intercepted packet. In such a scenario, you need to allocate a tunnel interface and assign it to the dynamic flow capture process for FlowTapLite to use.
