Description: The ipQosTable defines the classifier rules that are applied to IP traffic arriving this interface in a particular direction. The rules are processed in order, i.e. each rule has a link to the next rule. The set of rules is processed until a match occurs, that means the rule's associated filter matches and the specified action is performed (set the IP headers TOS field, specify a service class for QoS). The set of these rules to be processed can be defined for each interface.
