Overview

Traffic mirroring copies specified packets to a specific destination for packet analysis and monitoring.
Traffic mirroring is implemented through QoS policies. In other words, you define traffic classes and
configure match criteria to classify packets to be mirrored, and then you configure traffic behaviors to
mirror packets that fit the match criteria to the specified destination. You can use traffic mirroring to
flexibly classify packets by defining match criteria and obtain accurate statistics. The MSR routers support
mirroring traffic to an interface, which is to copy the matching packets to a destination interface.
For more information about QoS policies, traffic classes, and traffic behaviors, see ACL and QoS
Configuration Guide.
