Arista eAPI syntax has changed, and that this change becomes mandatory in EOS release 4.23
Does the latest DataMiner Arista driver support the new commands?
The latest version(s) of the Arista Manager protocol have been built against EOS release 4.21 (more specifically 4.21.1F). More information about this can be found in the driver information: https://catalog.dataminer.services/result/driver/4890
This means new command syntax will not be supported yet. A new range might need to be created to support this new release in case the commands that have been updated are not backwards compatible and they are used in the current Arista Manager version(s).
The latest driver does not yet support the new commands.
An update of the driver is scheduled and should be available soon.
We'll post an update to this topic once the update is available.
