9.4 Port Mirroring
This dialog allows you to configure and activate the port mirroring function of
the device.
In port mirroring, the valid data packets of one port, the source port, are cop-
ied to another, the destination port. The data traffic at the source port is not
influenced by port mirroring.
A management tool connected at the destination port, e.g. an RMON probe,
can thus monitor the source port’s data traffic in sending and receiving direc-
tion.
The destination port forwards the data to be sent and blocks data received.
Select the source port whose data traffic you want to observe.
Select the destination port to which you have connected your manage-
ment tool.
Select "enabled" to switch on the function.
The "Delete" button in the dialog allows you to reset all the port mirroring set-
tings of the device to the state on delivery.
Note: In active port mirroring, the specified port is used solely for observation
purposes.
