Port Mirroring

The port mirroring function enables you to review the data traffic from a group of ports on the device for diagnostic purposes. The device forwards (mirrors) the data for the source ports to the destination. A management tool connected at the destination port, e.g. an RMON probe, can thus monitor the data traffic of the source ports in the sending and receiving directions. The device does not affect the data traffic on the source ports during port mirroring.

Note: The destination port needs sufficient bandwidth to receive the data stream. When the copied data stream exceeds the bandwidth of the destination port, the device discards surplus data packets on the destination port.

You use physical ports as source or destination ports.

The MACH4002 24/48 + 4G and the Power MICE support up to 8 source ports.
