Requirements and Limitations for the Traffic Engineering Class Matrix

When you configure a traffic engineering class matrix, be aware of the following requirements and limitations:

A mapping configuration is local and affects only the router on which it is configured. It does not affect other systems participating in the differentiated services domain. However, for a Differentiated Services domain to function properly, you need to configure the same traffic engineering class matrix on all the routers participating in the same domain.
When explicitly configuring traffic engineering classes, you must configure the classes in sequence (te0, te1, te2, te3, and so on); otherwise, the configuration commit operation fails.

The first traffic engineering class you configure must be te0; otherwise, the configuration commit operation fails.
