Binding Layer 2 Port Mirroring to Ports Grouped at the FPC Level
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 DPC or to a specific FPC in the router (or switch)
chassis. This is known as binding a named instance of Layer 2 port mirroring at the FPC
level of the router (or switch) chassis. The port mirroring properties specified in the named
instance are applied to all physical ports associated with all Packet Forwarding Engines
on the specified DPC or FPC.
NOTE: You can also bind a named instance of Layer 2 port mirroring to a
specific Packet Forwarding Engine on a 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 DPC or FPC override any
port-mirroring properties configured at the global level.
•
Port-mirroring properties bound to a specific Packet Forwarding Engine
override any port-mirroring properties configured at the DPC or FPC 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 DPC or FPC, you can bind two distinct Layer 2 port-mirroring
specifications to a single group of ports.
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 or FPCs in the MX Series
router and in the EX Series switch, the number of Packet Forwarding Engines on each,
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 DPC or FPC and its Packet
Forwarding Engines:
