SNMP OIDs for individual power usage per port on Zyxel GS1920-8HPv2

DigitalClark · June 7

Hello,

I'm trying to integrate some controls from my Zyxel GS1920-8HPv2 switch into Home Assistant via SNMP. I've managed to toggle each ports power using "pethPsePortAdminEnable" 1.3.6.1.2.1.105.1.1.1.3.1.<port>, but now I'm trying to fetch the power consumption per port. I've downloaded the MIBs and walked the agent but couldn't make any sense of something that could refer to power consumption per port. In RFC 3621 I also only find a OID for the total power consumption (pethMainPseConsumptionPower) of the whole switch (and only as an integer, not float).

Is there a way to obtain the OIDs for the individual ports?

Thank you!

Hi @DigitalClark ,

GS1920-8HPv2 is a smart-managed switch. It does not feature a special MIB to get the PoE consumption for a specified port.

However, I would like to share with you that the Nebula control center can check PoE consumption per port. This free function can be found in Menu > Configure > Switches > Switch ports.

Hi users,

Recognizing the usefulness of MIB to monitor the PoE consumption for specific ports, we plan to implement this feature in an upcoming update.

Please stay tuned to the SWITCH NEW RELEASE for the latest enhancements and updates.

Now this is some great news! Great job Zyxel Team!
Do you also plan to implement this for my specific model (GS-1920-8HPv2)?

In the meantime, I came up with the solution to control the PoE ports over SNMP and fetch the PoE consumption data via a script executing SSH that runs the show pwr command on the switch on an interval and then parsing the values. But a native SNMP solution would be ideal ;-)!

Looking forward to the update!

Hi @DigitalClark ,

The 1920 switch series, including your model GS-1920-8HPv2, will have MIB functionality to monitor PoE consumption for specific ports.

Stay tuned and explore this new feature in the next time!

Could this feature be rolled out to other smart managed switch firmware updates please.

I have XS1930-12HP and XGS1930-28HP switches.

Hi @FlamencoAssassin ,

MIB functionality to monitor PoE consumption for specific ports will be rolled out in upcoming firmware updates for XS1930-12HP and XGS1930-28HP switches as well.

Thanks @Zyxel_Judy that's excellent news.

Hi @Zyxel_Judy,

because the response via MIB is an integer, would it be possible for you to send the POE consumption in mW? Webinterface shows 3.15W as an example, so via MIB that would be 3150mW.
When can we expect the new firmware?
Many greetings Chris

Excellent idea!

Hi @Chris77 , @FlamencoAssassin

The power consumption per port is displayed in milliwatts (mW) in the Web GUI. Additionally, the power consumption per port in the MIB is also set to be shown in milliwatts (mW).

You can check it when the feature is released in the next time.
