Binding Layer 2 Port Mirroring to Ports Grouped at the PIC Level

32
On an MX Series router and on an EX Series switch, you can bind a named instance of
Layer 2 port mirroring to the ports associated with a specific Packet Forwarding Engine
(on a DPC) or to the ports associated with a specific PIC (installed in an FPC). This is
known as binding a named instance of Layer 2 port mirroring at the PIC level of the router
(or switch) chassis. The port-mirroring properties specified in the named instance are
applied to all physical ports associated with the specified Packet Forwarding Engine.
NOTE: You can also bind a named instance of Layer 2 port mirroring to a
specific DPC or FPC in the router (or switch) chassis.
For any packet-type family supported by Layer 2 port mirroring:
Port-mirroring properties bound to a specific Packet Forwarding Engine
override any port-mirroring properties configured at the DPC or FPC level.
Port-mirroring properties bound to a specific DPC or FPC override any
port-mirroring properties configured at the global level.
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 Packet Forwarding Engine or PIC, you can bind two distinct Layer 2
port mirroring specifications to a single group of ports.
For MX960 routers, there is a one-to-one mapping of Packet Forwarding Engines to
Ethernet ports. Therefore, on MX960 routers only, you can bind a named instance of
Layer 2 port mirroring to a specific port by binding the instance to the Packet Forwarding
Engine associated with the port.
Before you begin, complete the following tasks:
Define a named instance of Layer 2 port mirroring. See Defining a Named Instance of
Layer 2 Port Mirroring.
Display information about the number and types of DPCs in the MX Series router or in
the EX Series switch, the number of Packet Forwarding Engines on each DPC, and the
number and types of ports per Packet Forwarding Engine. See Displaying Information
About DPCs or FPCs in an MX Series Router.
To bind a named instance of Layer 2 port mirroring to a Packet Forwarding Engine:
Enable configuration of the router (or switch) chassis properties:
1.

user@host# edit chassis
Enable configuration of a Packet Forwarding Engine or PIC:
2.
[edit chassis]
user@host# edit fpc slot-number
