Options to choose from are Enable and Disabled. This function is used to enable the propagation of the topology change notifications from the sub-ERP instance to the major instance. Select the checkbox and then select the revertive state. Options to choose from are Enable and Disabled. This function is used to revert back to the working transport entity, for example, when the RPL was blocked. Select the checkbox and enter the guard timer value here. This value must be between 10 and 2000 milliseconds. By default, this value is 500 milliseconds. Select the checkbox and enter hold-off timer value here. This value must be between 0 and 10 seconds. By default, this value is 0 seconds. Select the checkbox and enter the WTR timer value here. This value must be between 1 and 12 minutes. By default, this value is 5 minutes.

Loopback Detection The Loopback Detection (LBD) function is used to detect the loop created by a specific port. This feature is used to temporarily shut down a port on the Switch when a CTP (Configuration Testing Protocol) packet has been looped back to the Switch. When the Switch detects CTP packets received from a port or a VLAN, this signifies a loop on the network. The Switch will automatically block the port or the VLAN and send an alert to the administrator. The Loopback Detection port will restart (change to normal state) when the Loopback DetectionRecover Time times out. The Loopback Detection function can be implemented on a range of ports at a time. The user may enable or disable this function using the drop-down menu. To view the following window, click L2 Features>Loopback Detection, as shown below: 152
