Layer 2 Port Mirroring for a DPC or a Packet Forwarding Engine

You can configure multiple instances of Layer 2 port mirroring to enable different Packet Forwarding Engines to mirror packets to different destinations. You can bind a port-mirroring instance to a specific DPC or to a specific Packet Forwarding Engine.

Note: MX-series routers use DPCs rather than FPCs and therefore do not support physical interface cards (PICs). In the JUNOS CLI, though, you use the FPC syntax to configure or display information about DPCs, and you use the PIC syntax to configure or display information about Packet Forwarding Engines on the DPCs.

The following sections describe how to configure Layer 2 port mirroring for a specific DPC or Packet Forwarding Engine:

• Configuring Layer 2 Port-Mirroring Instances
• Determining the Number of DPCs in an MX-series Router
• Binding a Layer 2 Port-Mirroring Instance to a DPC
• Binding a Layer 2 Port-Mirroring Instance to a Packet Forwarding Engine
• Precedence of Port-Mirroring Instances at Different Levels of the Chassis
