Port Mirroring

With the port mirroring function, you copy the data stream of one or more ports to another
interface to be able to analyze this data stream without disturbing operation.
Note
If the maximum data rate of the mirrored port is higher than that of the monitor port, data
may be lost and the monitor port no longer reflects the data traffic at the mirrored port.
Several ports can be mirrored to one monitor port at the same time.
Mirroring a port does not work beyond switch core boundaries.
Disable port mirroring if you want to connect a normal end device to the monitor port.
