On logical interface ge-2/0/1.0
the Layer 2 port mirroring properties in the named instance
the port mirroring properties specified in
ge-2/0/1.0 under the following conditions:
The firewall filter
pm_filter_1
The named instance pm_instance_1
Even if the named instance
the router (or switch) chassis at FPC 2, PIC 0, the port mirroring properties specified in
remain in effect at logical interface
pm_instance_1
pm_filter_1 .
On logical interface ge-2/0/1.1
port mirroring properties in effect at the underlying physical interface
example, the port mirroring properties specified in
ports associated with FPC 2, PIC 0 under the following conditions:
The firewall filter
pm_filter_2
The named instance
pm_instance_2
The named instance
pm_instance_2
at FPC 2, PIC 0 (as shown in step 2).
If you disable the named instance
ports associated with FPC 2, PIC 0, then—if global Layer 2 port mirroring properties had
been configured—the global port mirroring properties would be used at logical interface
ge-2/0/1.1 through firewall filter
NOTE: There is a limitation to a Layer 2 port mirroring firewall filter in which
you implicitly reference Layer 2 port mirroring properties by including the
port-mirror statement. If multiple named instances of Layer 2 port mirroring
are bound to the underlying physical interface, then only the first binding in
the stanza (or the only binding) is used at the logical interface. This is done
mainly for backward compatibility.
