Transceiver Rx/Tx on Cisco ASR 9001

Denis Klimek added a comment - 2018/05/29 07:40 AM Issue is caused by faulty coded optical transceiver from our vendor. Took some time to figure it out.

Denis Klimek added a comment - 2018/04/27 07:21 AM Thanks for your quick reply. We figured out that only onboard SFP+ ports are affected from this bug. Interfaces on a MPA (module line card) are not affected from this issue. We will report to Cisco TAC.

Mike Stupalov added a comment - 2018/04/26 09:44 AM Yep, this is another IOS XR bug (for new version). I see you use ios xr firmware 6.1.4. All this sensors return incorrect data, for example Tx sensors. See entSensorValue and entSensorStatus entPhysicalDescr.18995616 = Transceiver Tx Power Sensor entSensorType.18995616 = watts entSensorScale.18995616 = milli entSensorPrecision.18995616 = 3 entSensorValue.18995616 = -32768 entSensorStatus.18995616 = unavailable   entPhysicalDescr.47349219 = Transceiver Tx Power Sensor entSensorType.47349219 = watts entSensorScale.47349219 = milli entSensorPrecision.47349219 = 3 entSensorValue.47349219 = -32768 entSensorStatus.47349219 = unavailable Rx and other dom sensors - same. Write Cisco TAC
