> # SFP Diagnostics

> The error message related to SFP failures is written to the syslog. You can listen to the syslog for events related to SFP failures. The values, low or high alarm, and the warning are checked for the following parameters:

> - TX Power
> - RX Power
> - Temperature
> - Voltage
> - Current

> The SFP 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 at least one of the monitoring parameters of the sensors on the transceiver in an interface.

> The CISCO-INTERFACE-XCVR-MONITOR-MIB contains the SFP notification trap information. Refer to the Cisco MDS 9000 Family MIB Quick Reference for more information on this MIB.
