Description: Information about a single traffic class. Traffic classes are identified by their associated interface's ifIndex and their name. (Which means class names must be unique for a particular interface.)

Traffic classes can be created and destroyed using this table's xtmClassRowStatus object. A class cannot be used by the run-time system (xtmClassRowStatus = 'active(1)') if it does not follow the rules listed in the DESCRIPTION of the previous object. In this case, the xtmClassRowStatus will remain 'notReady(3)' and the xtmClassOperStatus will be 'downConflict(3)'.

Also, in order to become active, the user must have specified a valid value for xtmClassParent and xtmClassRate. All other settable objects may be left at their default values.

Finally, the following objects cannot be modified once the row is active: xtmClassParent, and xtmClassQueueElasticityFactor.
