Description (partial)

Symptom:
" show inter trans detail " command output the RX & TX optical power is abnormal. but not find have business impact , only find display error.
BGL.M.14-3900-1#show interfaces transceiver detail
mA: milliamperes, dBm: decibels (milliwatts), NA or N/A: not applicable.
++ : high alarm, +  : high warning, -  : low warning, -- : low alarm.
A2D readouts (if they differ), are reported in parentheses.
The threshold values are calibrated.
