Hi Yiannis,

Thank you for the post.

This error message occurs since the index of the required OIDs changed. However, we also had a bug in a old version of PRTG that triggered this error. Therefore, please follow these steps:

  1. Update PRTG to the latest Version
  2. (If the Sensors does not work again) Change the SNMP request mode to "Single Get" - This is defined in the corresponding device settings (under "SNMP Compatibility Options")
  3. Recreate the Sensor

Best Regards,

This has been broken on my Cisco 3850 switches since the PRTG version in stable release on 4/15/2019. After upgrade to 20.2.58.1629+ today and trying all the noted steps again (recreate sensor, switch to single get) this still does not work and I continue to get flapping PE269 errors.

Hey there,

  • What scanning interval do you use?
  • Is the iOS version up-to-date?

Kind regards,

Hello there,

I'm afraid there is no update to this. We are still working on this issue. When there is a fix, you will find it in our release notes.


Kind regards

Hello Felix, We are also experiencing this issue on various CAT9K model switches/Wireless controller.

Hello One,

May I ask for the PRTG version which you are using? If it's the latest version 21.3.69.1333+, also check if re-adding the sensor works properly for the new sensor.


Kind regards,
