Description: ONU serial port loopback test.

What is onuSerialPortLoopback?

This object triggers a loopback test on the ONU's serial port when set to true. Admins use this to verify the serial port's hardware and cabling are functioning correctly without needing a device physically connected on the far end. Setting this to true(1) initiates a loopback test that an admin can use to confirm the serial port itself is not faulty before troubleshooting the connected equipment.

Examples

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11606.10.101.27.1.1.17
snmpwalk -v2c -c public <target> NMS-EPON-ONU-SERIAL-PORT::onuSerialPortLoopback

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.11606.10.101.27.1.1.17.1
snmpget -v2c -c public <target> NMS-EPON-ONU-SERIAL-PORT::onuSerialPortLoopback.1
