How to Monitor the RSL, TX and RS power of a trunk fiber interface

Modified on 2025-06-10 22:03:25 +0200

Hi,

I am having an issue. I want to be monitoring the RSL, TX and RS power level of a trunk interface connected to a Cisco layer 3 switch on my network. I have tried different ways of doing that but none is yielding any result.

i can monitor the live traffic (ie Total traffic, traffic in and traffic out) on that interface. But i also want to be monitoring the RSL, TX and RS power also.

Do anyone have answer to these?

Hello ibegbud,
thank you for your KB-Post.

Please check our built-in SNMP Cisco System Health sensor, while deploying the sensor several variants will be offered, including the "Cisco System Health Other". This variation of the sensor will display TX/RX power readings (if available/reported).

For rsl, you might have to check with Cisco or review the MIB's documentation to locate that property, you should be able to monitor it with a Custom SNMP Sensor if the information is available via SNMP.

Best Regards,
