Layer 2 Port Mirroring Global Instance
On an MX Series router, you can configure a set of port-mirroring properties that implicitly apply to packets received on all ports in the router chassis. This set of port-mirroring properties is the global instance of Layer 2 port mirroring for the router.
Within the global instance configuration, you can specify a set of mirror destination properties for each packet address family supported by Layer 2 port mirroring.
For a general description of Layer 2 port-mirroring properties, see Layer 2 Port Mirroring Properties. For a comparison of the types of Layer 2 port mirroring available on an MX Series router, see Application of Layer 2 Port Mirroring Types.
