Table 7-16. Port Monitor Commands CLI Command monitor session show monitor session Description Configure a probe port and a monitored port for monitor session (port monitoring). Displays status of port monitoring. 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. 332 Configuring Switching Information
