Configuring Traffic Sampling

Traffic sampling enables you to copy traffic to a Physical Interface Card (PIC) that performs flow accounting while the router forwards the packet to its original destination. You can configure the router to perform sampling in either of two locations:

• On the Routing Engine, using the sampled process. To select this method, use a filter (input or output) with a matching term that contains the then sample statement.
• On the Monitoring Services, Adaptive Services, or MultiServices PIC.

The following sections provide information about traffic sampling configuration:
