Figure 76 – Configuration > Port Mirroring
Selection options for the Source Ports are as follows:
TX (transmit) mode: Duplicates the data transmitted from the source port and forwards it to the Target Port.
Click “all” to include all ports into port mirroring.
RX (receive) mode: Duplicates the data that is received from the source port and forwards it to the Target
Port. Click “all” to include all ports into port mirroring.
Both (transmit and receive) mode: Duplicate both the data transmitted from and data sent to the source
port, and forwards all the data to the assigned Target Port. Click “all” to include all ports into port mirroring.
None: Turns off the mirroring of the port. Click “all” to remove all ports from mirroring.
Configuration > Power Saving
The Power Saving mode feature reduces power consumption automatically when the RJ-45 port is link down
or the connected devices are turned off. Less power will be consumed also when the short cable is used
(less than 20 meters).
By reducing power consumption, less heat is produced, resulting in extended product life and lower
operating costs. By default, the Power Saving mode is enabled. Click Apply to make the change effective.

Configuration > Loopback Detection
The Loopback Detection function is used to detect the loop created by a specific port while Spanning Tree
Protocol (STP) is not enabled in the network, especially when the down links are hubs or unmanaged
switches. The Switch will automatically shutdown the port and sends a log to the administrator. The
Loopback Detection port will be unlocked when the Loopback Detection Recover Time times out. The
Loopback Detection function can be implemented on a range of ports at the same time. You may enable or
disable this function using the pull-down menu.
