While creating new traffic class, the following appears: ERROR 3401: Failed to add matching rule to traffic class

Error 3401 indicates that the number of traffic classes hit the limit of available traffic class on PacketShaper.

 

Issue the CLI command sys limit to verify the number of current and remaining traffic classes available on PacketShaper.

If you have reached the class limit for your mode, you can delete any unwanted traffic classes from the current configuration.
