Configuring a Flow-Tap Interface on MX, M and T Series Routers
To configure an AS PIC interface for the flow-tap service, include the interface statement at the [edit services flow-tap] hierarchy level:
interface sp-fpc/pic/port.unit-number;
You can assign any AS PIC in the active monitoring station for flow-tap service, and use any logical unit on the PIC.
You cannot configure dynamic flow capture and flow-tap features on the same router simultaneously.
You must also configure the logical interface at the [edit interfaces] hierarchy level:
interface sp-fpc/pic/port {
unit logical-unit-number {
family inet;
}
}
