It seemed to me that monitoring SFP DDM/diagnostic values (TX/RX power, voltage, temperature) would be a good practice for preventive maintenance. Having recently spent over a week troubleshooting problems in an optical link, I thought maybe looking at SNMP-DDM graphs would prevent end user complaints next time.
When looking for a switch with 8-16 SFP ports, I was very surprised to find that monitoring SFP DDM is not supported over SNMP.
- Planet MGSD-10080F provides the data only using browser.
- Both Unifi EdgeSwitch ES-12F and Cisco SG350-10SFP provide data over CLI and browser. Unifi confirmed the data is not available over SNMP. I've yet to hear back from Cisco, but I'm afraid the answer is the same.
SFP DDM is widespread, which has to mean it's useful, right? Yet the data can be only accessed manually using CLI or browser, is not available automatically using SNMP.
Does it mean continuous values tracking / graphs are actually not used in practice and alerting is implemented within switch using Warning/Alarm thresholds and SNMP traps?
