ethIfOutSpeed 1.3.6.1.4.1.2928.2.2.1.3.2.1.21

An estimate of the interface's current output bandwidth in bits per second. If the interface is a physical interface (represented in ethDot3Table), then this value is the same as ethDot3ActiveSpeed. If the interface represents an Ethernet Transport Service Trail Termination Point (ETS TTP), then this value is the sum of the bandwidth of all originating channels connected to this interface. If the bandwidth of the interface is greater than the maximum value reportable by this object then this object should report its maximum value (4,294,967,295) and ethIfOutHighSpeed must be used to report the interface's speed.
