Configuring a Port Mirroring Session Using CLI Commands For information about the CLI commands that perform this function, see the following chapter in the CLI Reference Guide: • Port Monitor Commands 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 display the Flow Based Mirroring page, click Switching > Traffic Mirroring > Flow Based Mirroring in the tree view. Figure 7-31. Flow Based Mirroring The Flow Based Mirroring page contains the following fields: • Policy Name - Selects policy to associate with a traffic class. Policy Name is defined using the DiffServ "Policy Configuration" web page. • Member Classes - Selects the traffic class associated with this policy. Member Class is defined using the DiffServ "Class Configuration" web page. • Copy to Interface - When checked, this feature permits packets to be copied to either a unit/port or LAG.
