When you have an SD-WAN deployment in your lab, you will probably use the console access a lot to do some checks. With 20.7.1, a lot more logging will be generated about unlicensed devices. When you type in the console, the number of messages will exponentially increase until it comes both annoying and unworkable.

:: The Workaround
Here is how to fix it.
First, let’s check what the format of the message is:

- Facility: %SMART_LIC-2
- Severity: -2-
- Mnemonic: PLATFORM_ERROR
- Msg body: Smart Licensing has encountered an internal software error. Contact TAC: The platform provided UDI list has invalid values: ; udi_sn is empty; udi_sn is null or empty for valid udi_p
We can filter based on these facts and choose to drop them. As this is a test lab, I’m not really interested in filtering wisely. I just need to get rid of that message filling up my sessions.
In production, try to filter as tight as possible to prevent lost messages!
Configuration:
!
logging discriminator GO-AWAY mnemonic drops PLATFORM_ERROR
logging console discriminator GO-AWAY
!
Obviously, this will filter all events based on the PLATFORM_ERROR mnemonic.
Since logging discriminator is not supported in the vManage GUI, we need to use a CLI Feature template to overcome this unsupported feature.
:: CLI Feature template
Go to Configuration / Templates / Feature
Add Template, select the appropriate device mode and choose Cli Add-On template
Attach to the template. Open the template and navigate to Additional templates section.
Attach the feature template as follows and click Update. The update will be pushed to all devices attached to the device template.
