Thats slightly annoying - about to deploy a few of these myself.

I'd suggest also checking a manual discover/poll and make sure its not being missed due to a timeout or something - I've had similar issues with some older HPE switches, where certain SNMP requests take a bit longer, and I had timeout set to 1sec - sometimes responses lagged and made for some interesting graphs!
SNMP maxrep and timeout are the 2 things I'd fiddle with if this is the case.

Hi,

 because device not report it in snmp 🤷‍♂️

See entities which contain entSensorValue oid.

Ask Cisco TAC about issue.

Hello,

 

I noticed that on Cisco 9200 series switches sometimes SFP module is not detected and presented in the Port Sensors section, anyone suggest why ?
