Configuration > Port Mirroring
Port Mirroring is a method of monitoring network traffic that forwards a copy of each incoming and/or
outgoing packet from one port of the Switch to another port, where the packet can be studied. This enables
network managers to better monitor network performances.
Figure 4.89 – Configuration > Port Mirroring
Port Mirroring:
Enables or Disables the port mirroring feature.
Target Port:
Specifies the target port.
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 (TX and RX) 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.
Click

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 shut down 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.
