Defining Port Mirroring Sessions Port mirroring does the following: • Monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets from one port to a monitoring port. • Can be used as a diagnostic tool and/or a debugging feature. • Enables device performance and monitoring. Port mirroring is configured by selecting a specific port to copy all packets, and different ports from which the packets are copied. Before configuring Port Mirroring, note the following: • Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets, from a monitored port to a monitoring port. • Monitored port cannot operate faster than the monitoring port. • All the RX/TX packets should be monitored to the same port. The following restrictions apply to ports configured to be destination ports: • Ports cannot be configured as a source port. • Ports cannot be a LAG member. • IP interfaces are not configured on the port. • GVRP is not enabled on the port. • The port is not a VLAN member. • Only one destination port can be defined. The following restrictions apply to ports configured to be source ports: • Source Ports cannot be a LAG member. • Ports cannot be configured as a destination port. • Mirroring supports 4 ports in this device. 312 Configuring Switch Information
