                      The value unknown(2) is returned when the MAU's

                      being initialized.

                      If the MAU is not jabbering the agent returns
                      noJabber(3).  This is the 'normal' state.

                      If the MAU is in jabber state the agent returns

                      does not increment at the symbol rate.  It can

                      maximum rate of once per 100 ms until the next
                      carrier event.

                      This counter increments only for MAUs of type
                      dot3MauType100BaseT4, dot3MauType100BaseTX, and

                      A MAU in the operational(3) state is fully
                      functional, operates, and passes signals to its
                      attached DTE or repeater port in accordance to
                      its specification.

                      A MAU in standby(4) state forces DI and CI to
                      idle and the media transmitter to idle or fault,
                      if supported.  Standby(4) mode only applies to
                      link type MAUs.  The state of
                      ifMauMediaAvailable is unaffected.

                      A MAU in shutdown(5) state assumes the same
                      condition on DI, CI, and the media transmitter
                      as though it were powered down or not connected.
                      The MAU MAY return other(1) value for the
                      ifMauJabberState and ifMauMediaAvailable objects
                      when it is in this state.  For an AUI, this
                      state will remove power from the AUI.

                      Setting this variable to the value reset(6)
                      resets the MAU in the same manner as a
                      power-off, power-on cycle of at least one-half
                      second would.  The agent is not required to
                      return the value reset (6).

                      Setting this variable to the value
                      operational(3), standby(4), or shutdown(5)
                      causes the MAU to assume the respective state
                      except that setting a mixing-type MAU or an AUI
                      to standby(4) will cause the MAU to enter the
