Example: Layer 2 Port Mirroring with Multiple Instances
Because you can configure more than one port-mirroring instance, care is required when
specifying which instance is meant. This topic contains the following information:

Example: Configuring Multiple Instances of Layer 2 Port Mirroring
This configuration example illustrates the configuration of Layer 2 port mirroring at the
physical interfaces associated with FPC 2, PIC 0 and at two logical interfaces on one of
those ports.
At the physical interface levels of the router (or switch) chassis, two named instances
of port mirroring are configured and then bound to the group of physical ports associated
with FPC 2, PIC 0.
At two of the logical interfaces on physical interface ge-2/0/1, two Layer 2 port-mirroring
firewall filters are applied to the input traffic. One filter explicitly references the port
mirroring properties specified in one of the named instances of port mirroring. The other
filter implicitly references the port mirroring properties in effect on the underlying physical
interface ge-2/0/1.
The resulting configuration is an example of the relationships that can exist between
multiple instances of Layer 2 port mirroring applied to an MX Series router or an EX Series
switch.

Configure two named instances of Layer 2 port mirroring (pm_instance_1 and
pm_instance_2), and include mirror destination properties for VLAN traffic
(family ethernet-switching):
