D-Link EasySmart Switch User Manual 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 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. NOTE: The target ports will stop mirroring packets if there are unknown tags or destination packets sent out by source ports. L2 Features > 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. 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 a time. Figure 51- L2 Features > Loopback Detection Loopback Detection: Enable or disable Loopback detection. The default is Disabled. Interval (1-32767): Set a Loop detection Interval between 1 and 32767 seconds. The default is 1 seconds. Recover Time (0 or 60-1000000): Time allowed (in seconds) for recovery when a Loopback is detected. The Loop Detection Recover Time can be set at 0 seconds, or 60 to 1000000 seconds. Entering 0 will disable the Loop Detection Recover Time. The default is 60 seconds. From Port: The beginning of a consecutive group of ports may be configured starting with the selected port. To Port: The ending of a consecutive group of ports may be configured starting with the selected port. State: Use the drop-down menu to toggle between Enabled and Disabled. Default is Disabled.

sent out by source ports.
L2 Features > 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. 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 a time.
