For MX-series routers, there is a one-to-one mapping of the Packet Forwarding Engines and the PICs. Therefore, you can override the port mirroring instance properties configured at the DPC level and configure a PIC-level port-mirroring instance. To bind a port mirroring instance to a specific Packet Forwarding Engine and its associated ports, include the include the port-mirror-instance pm-instance-name statement at the [edit chassis fpc slot-number pic number] hierarchy level.
- [edit chassis]
- fpc slot-number {
- port-mirror-instance pm-instance-name-a;
-
- pic slot-number {
- port-mirror-instance pm-instance-name-b;
- }
- }
