Flow Based Mirroring
The flow based mirroring feature builds upon the DiffServ component in QoS. In QoS, the user creates
traffic classes to define match criteria, then policies to define the action to be taken on that traffic class.
Flow based mirroring allows the user to copy certain types of traffic to a single destination port. This
provides flexibility—instead of mirroring all ingress or egress traffic on a port, the switch can mirror a
subset of that traffic. You can configure the switch to mirror flows based on Layer 2, Layer 3, and Layer 4
information.
Use the Flow Based Mirroring page to specify flow-based mirroring ports.
To displ ay t he Flow Based Mirroring page, click Switching > Traffic Mirroring > Flow Based Mirroring
