1.3.6.1.2.1.10.7.1.1.1 |
| An index value that uniquely identifies an
interface to an ethernet-like medium. The
interface identified by a particular value of this
index is the same interface as identified by the
same value of ifIndex. |

| dot3InitializeMac |
1.3.6.1.2.1.10.7.1.1.2 |
| The initialization status of the MAC and PLS
(Physical Layer Signalling) subsystems for a
particular interface. The value initialized(1)
signifies that the subsystems for a particular
interface have been previously initialized; the
value uninitialized(2) signifies that they have
not been previously initialized.
Each alteration of an instance of this object to
either of the values initialized(1) or
uninitialized(2) is analogous to an invocation of
the initializeMAC action defined in [9] and has
the effect of (re-)initializing the MAC and PLS
subsystems for the associated interface. In
particular,
all management counters pertaining to the MAC
and PLS subsystems for said interface are
reset to zero;
the receive and transmit layer management
state variables (receiveEnabled and
transmitEnabled in [9]) are set to enable
reception and transmission of frames;
the promiscuous receive function is disabled;
and
multicast reception is disabled. |

|
| dot3MacSubLayerStatus |
1.3.6.1.2.1.10.7.1.1.3 |
| The operational status of the MAC sublayer for a
particular interface. The value enabled(1)
signifies that the MAC sublayer for said interface
is operational for both transmitting and receiving
frames -- that is, that the value of both the
receive and transmit layer management state
variables (receiveEnabled and transmitEnabled in
[9]) for said interface are true. The value
disabled(2) signifies that the MAC sublayer for
said interface is not operational for either
transmitting or receiving frames. In particular,
the value of an instance of this object is
disabled(2) whenever the value of the
corresponding instance of the dot3Enabled object
is false(2).
Each alteration of an instance of this object to
the value enabled(1) is analogous to an invocation
of the enableMACSublayer action defined in [9] and
has the effect of starting normal transmit and
receive operations (from the ``idle'' state) on
the associated interface. In particular, such an
alteration has the effect of resetting the PLS for
said interface and of setting the receive and
transmit layer management state variables
(receiveEnabled and transmitEnabled in [9]) to be
true.
Each alteration of an instance of this object to
the value disabled(2) is analogous to an
invocation of the disableMACSublayer action
defined in [9] and has the effect of terminating
transmit and receive operations on the associated
interface. In particular, such an alteration has
the effect of setting the receive and transmit
layer management state variables (receiveEnabled
and transmitEnabled in [9]) to be false. Any
transmissions/receptions in progress are completed
before operation is terminated. |

| dot3MulticastReceiveStatus |
1.3.6.1.2.1.10.7.1.1.4 |
| The multicast receive status for a particular
interface. The value enabled(1) signifies that
reception of multicast frames by the MAC sublayer
is enabled on said interface. The value
disabled(2) signifies that reception of multicast
frames by the MAC sublayer is not enabled on said
interface.
Each alteration of an instance of this object to
the value enabled(1) is analogous to an invocation
of the enableMulticastReceive action defined in
[9] and has the effect of enabling multicast frame
reception on the associated interface. Actual
reception of multicast frames is only possible on
an interface when the values for the associated
instances of the dot3MulticastReceiveStatus and
dot3MacSubLayerStatus objects are enabled(1) and
enabled(1), respectively.
Each alteration of an instance of this object to
the value disabled(2) is analogous to an
invocation of the disableMulticastReceive action
defined in [9] and has the effect of inhibiting
multicast frame reception on the associated
interface. |

| dot3TxEnabled |
1.3.6.1.2.1.10.7.1.1.5 |
| 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. |
