Details:
- NCS4201-SA running version 17.06.03, shows transceiver Threshold Violation alerts on all the ports
%SFF8472-3-THRESHOLD_VIOLATION: Gi0/0/4: Rx power high warning; Operating value: -1.9 dBm, Threshold value: -3.0 dBm.
The values are incorrect, all report the same TX and RX power.
The ones in the Tengig spots are completely different types of SFP’s but show the same issue, so this is not specific to one type of SFP. I think this is not tied to a specific SPF.

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).

All interfaces have remained up and passing traffic, so possibly a cosmetic issue.
