The transmit layer management state variable (transmitEnabled as defined in [9]) for a particular interface. The value true(1) signifies that the MAC frame transmission is enabled on said interface. The value false(2) signifies that the MAC frame transmission is inhibited on said interface. In particular, the value of an instance of this object is false(2) whenever the value of the corresponding instance of the dot3MacSubLayerStatus object is disabled(2).

Each alteration of an instance of this object to the value true(1) is analogous to an invocation of the enableTransmit action defined in [9] and has the effect of enabling MAC sublayer frame transmission on the associated interface. In particular, such an alteration has the effect of setting the transmit layer management state variable (transmitEnabled in [9]) for said interface to be true.

Each alteration of an instance of this object to the value false(2) is analogous to an invocation of the disableTransmit action defined in [9] and has the effect of inhibiting MAC sublayer frame transmission on the associated interface. In particular, such an alteration has the effect of setting the transmit layer management state variable (transmitEnabled in [9]) for said interface to be false. Any transmissions in progress are completed before transmission is inhibited.
