My Nexus 7k is seeming to generate false traps for my transceivers. The traps denote a change in the health of the transceiver. However, neither the logs nor when checking the relevant transceiver does there appear to be an issue with them. I have many similar type transceivers which do not generate the traps. The traps are generated at odd times and can be just two at a time or many. I have checked for bugs and cannot see any that might affect the software that is running on the 7k. I will try to re-seat and also replace if necessary but as there is no user impact being reported or errors on the interfaces being generated and as this is a live environment, I do not want to make any necessary changes that will impact the business. I am not very familiar with the SNMP traps so any input into why these are being generated would be greatly appreciated. Also the numbers that directly follow the interface slot/number (highlighted in bold), do they have any useful meaning? The trap information is as follows:
Hostname : 10.10.10.1
Description :
Date : 2016-06-16 14:07:50
EventName : CIFXCVRMONSTATUSCHANGENOTIF
TrapOid : enterprises.9.9.706.0.1
Category : STATUS EVENTS
Severity : NORMAL
Trap Message : This notification trap indicates the current status of the alarm and warning monitoring parameters for all the sensors based on the digital diagnostic monitoring information. This notification is generated whenever there is a change in the status of atleast one of the monitoring parameters of the sensors on the transceiver in an interface.

An alert has been issued that requires your attention.
