Hi,
Receiving continuous logs about low Rx power on ASR 903 version 03.13.04.
%SFF8472-3-THRESHOLD_VIOLATION: Gi0/2/1: Rx power low warning; Operating value: -20.9 dBm, Threshold value: -19.0 dBm.
After verifying optical status, i am observing 2 different outputs,
----------------------------------------------------
show interfaces gigabitEthernet 0/2/1 transceiver
ITU Channel not available (Wavelength not available),
Transceiver is externally calibrated.
If device is externally calibrated, only calibrated values are printed.
++ : high alarm, + : high warning, - : low warning, -- : low alarm.
NA or N/A: not applicable, Tx: transmit, Rx: receive.
mA: milliamperes, dBm: decibels (milliwatts).

The Transceiver in slot 0 subslot 2 port 1 is enabled.
Module temperature = +43.210 C
Transceiver Tx supply voltage = 3314.8 mVolts
Transceiver Tx bias current = 24588 uAmps
Transceiver Tx power = -5.2 dBm
Transceiver Rx optical power = -15.2 dBm
-----------------------------------------------------------------------------
Can any one confirm is it a bug or we to change line card, as other ports on same line card having same issue.
