Digital Optical Monitoring: Receive Power CRITICAL for SFP+ in Loop Guard (MS130-8X)

I am curious IF this is expected reading for a MS130-8X SFP Loop Guard STP setting?  The receive power shows critical.  Is that because the port is in loop guard mode?  

I've swapped SFP+ modules to test a different SFP+ module and continue to get same "critical" reading.  Or how often do the sensor settings refresh?  Perhaps SFP+ module # 2 that I tested is OK but I've not yet waited long enough for it to provide an updated reading. 


Firmware: MS 17.1.1
Model: MS130-8X

Thanks for any feedback you might provide.

I just found it in the documentation: The dashboard periodically polls for SFP telemetry every 5 minutes.

And the module updated as well - appears the SFP+ module #1 was bad as #2 is getting good specs/readings.
