Layer 2 Port Mirroring Firewall Filters Overview
On an MX Series router and on an EX Series switch, you can configure a firewall filter term
to specify that Layer 2 port mirroring is to be applied to all packets at the interface to
which the firewall filter is applied.
You can apply a Layer 2 port-mirroring firewall filter to the input or output logical interfaces
(including aggregated Ethernet logical interfaces), to traffic forwarded or flooded to a
VLAN, or traffic forwarded or flooded to a VPLS routing instance.
MX Series routers and EX Series switches support Layer 2 port mirroring of VPLS (family
ethernet-switching or family vpls) traffic and Layer 2 VPN traffic with family ccc n a Layer 2
environment
Within a firewall filter term, you can specify the Layer 2 port-mirroring properties under
the then statement in either of the following ways:
•
Implicitly reference the Layer 2 port mirroring properties in effect on the port.
•
Explicitly reference a particular named instance of Layer 2 port mirroring.
