Hi !

I have a Cisco CGR-2010/K9 that shows wrong miliamperes readings when I use show interfaces transceiver detail:

Router#show interfaces transceiver detail
Transceiver monitoring is disabled for all interfaces.

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.

Do you know the root cause of this issue? Is this a normal behavior?

Thanks in advance!

I already did it, I upgraded from 15.8(3)M0a to 15.8(3)M8, do you know the software version that fixes this bug?

Thanks in advance.
