The following scenarios demonstrate how to configure port
mirroring using the ``traffic policy duplicate`` feature.
Port mirroring duplicates network packets and forwards copies
to monitoring destinations while preserving the original traffic flow.
``traffic selectors`` can be used to filter which packets
should be duplicated based on protocol, addresses, or other criteria.

Test duplicate local traffic to an interface
********************************************

Both ingress (link-in) and egress (link-out) traffic policies are applied
to duplicate all traffic to another physical interface.

Test duplicate local traffic to a remote IP
*******************************************

Description
===========

This scenario configures remote port mirroring on DUT0 ('eth0' interface).
Local-in and local-out traffic policies duplicate traffic to a remote IP address.
A traffic selector is configured to filter and duplicate only UDP traffic.

****************************************************
Test duplicate local traffic to a remote IP with VRF
****************************************************

Description
===========

This scenario configures remote port mirroring on DUT0 ('eth0' interface).
Local-in and local-out traffic policies duplicate traffic to a remote IP address.
The interface is configured within a VRF, which must be specified as the output VRF.
A traffic selector is configured to filter and duplicate only UDP traffic.
