7.3.2 Configuration Scheme
Enable loopback detection on ports 1/0/1-3 and configure SNMP to receive the
notifications. For detailed instructions about SNMP, refer to
Configuring SNMP & RMON
.
Here we introduce how to configure loopback detection and monitor the detection result
on the management interface of the switch.
Demonstrated with T1700X-16TS, the following sections provide configuration procedure
in two ways: using the GUI and using the CLI.
7.3.3 Using the GUI
1) Choose the menu Switching > Port > Loopback Detection to load the configuration
page.
2) In the Global Config section, enable loopback detection and web refresh globally. Keep
the default parameters and click Apply.

3) In the Port Config section, enable ports 1/0/1-3, select the operation mode as Port
based so that the port will be blocked when a loop is detected, and keep the recovery
mode as Auto so that the port will recover to normal status after the automatic recovery
time. Click Apply.
