Flow Mirroring

Flow Mirroring

Flow mirroring enables the device to copy the packets matching configured traffic classification rules to an observing port for analysis and monitoring. As shown in Figure 10-3, the mirrored port copies service flow 2 matching traffic classification rules to the observing port, and then the observing port forwards the copy of service flow 2 to the monitoring device.

Figure 10-3  Networking of flow mirroring

Flow mirroring is a traffic action. Actually, a traffic policy defining flow mirroring is applied to the system, a VLAN, or an interface. For details about the traffic policy, see "MQC Configuration" in Huawei AR Series Access Routers - CLI-based Configuration - Configuration Guide - QoS Configuration.
