or FPC override any port-mirroring properties bound at the global level or the MX Series
router (or switch) chassis.
On an MX Series router and on an EX Series switch, you can bind a named instance of
Layer 2 port mirroring to a specific Packet Forwarding Engine or PIC. The port-mirroring
properties in that instance are applied to all ports associated with the specified Packet
Forwarding Engine or PIC. Port-mirroring properties that are bound to a Packet Forwarding
Engine or PIC override any port-mirroring properties bound at the DPC or FPC that contains
them.
NOTE:
For MX960 routers, there is a one-to-one mapping of Packet
Forwarding Engines to Ethernet ports. Therefore, on MX960 routers only, you
can configure port-specific bindings of port-mirroring instances.
On an MX Series router and on an EX Series switch, you can apply up to two named
instances of Layer 2 port mirroring to the same group of ports within the router (or switch)
chassis. By applying two different port-mirroring instances to the same DPC, FPC, Packet
Forwarding Engine, or PIC, you can bind two distinct Layer 2 port mirroring specifications
to a single group of ports.
NOTE:
You can configure only one global instance of Layer 2 port mirroring
on an MX Series router and on an EX Series switch.
NOTE:
You can configure more than two port mirroring instances for each
FPC by configuring inline port mirroring. For information on inline port
mirroring, see
