| dot4IfIndex |
.1.3.6.1.3.7.1.1.1 |
|
The value of this object identifies the
802.4 interface for which this entry
contains management information. The
value of this object for a particular
interface has the same value as the
ifIndex object, defined in [4,6], for the
same interface.
|
| dot4Options |
.1.3.6.1.3.7.1.1.2 |
|
The optional parts of the 802.4
specification which are in use by this
station. The options of the 802.4
specification are represented by the
following values:
1 - Priority
2 - Request-With-Response
The value of this object is given by the
sum of the above representations for
those options in use on this interface.
The value zero indicates that no options
are in use.
|
| dot4State |
.1.3.6.1.3.7.1.1.3 |
|
The current state of the 802.4
interface. The value of other(1) is
used if the state is unknown
(e.g., due to an error condition).
|
| dot4Commands |
.1.3.6.1.3.7.1.1.4 |
|
Setting this object causes the station
to change the state of the interface as
indicated by the specified value. An
initialize(5) command causes the
interfaceto load its operational
parameters from its initialization
parameters; the value of
dot4InitInRingDesired determines
whether the station tries to enter the
logical ring immediately.
Note that the 802.4 specification
suggests a station remain Offline after a
'remote Network Management' reset(4),
until a 'local Network Management'
initialize(5) is performed.
Setting this object to a value of
no-op(1) has no effect. When read,
this object always has the value no-op(1).
|
| dot4MacAddrLen |

The MAC address of this station's
successor in the logical ring.
|
| dot4PreviousStation |
.1.3.6.1.3.7.1.1.7 |
|
The source MAC address of the last token
addressed to this station.
|
| dot4SlotTime |
.1.3.6.1.3.7.1.1.8 |
|
The maximum time any station need wait
for an immediate MAC-level response from
another station.
This value must the same in all stations on
the 802.4 network.
|
| dot4LastTokenRotTime |
.1.3.6.1.3.7.1.1.9 |
|
The observed token rotation time for the
last token rotation, timed from token
arrival to token arrival. A value of
zero indicates that the token is not
rotating.
|
| dot4HiPriTokenHoldTime |
.1.3.6.1.3.7.1.1.10 |
|
The maximum duration for which a station
can hold the token to transmit frames of
access class 6 (if the priority option is
implemented), or of any access class (if
the priority option is not implemented).
|
| dot4TargetRotTimeClass4 |
.1.3.6.1.3.7.1.1.11 |
|
If the priority scheme is being used,
this value specifies a limit on how long
a station can transmit frames at access
class 4. The limit is measured from the
time the station is able to start
transmitting frames at this access class
on one rotation, to the time it must stop
transmitting frames at this access class
on the next rotation. If the priority
scheme is not being used, this object has
the value 0.
|
| dot4TargetRotTimeClass2 |
.1.3.6.1.3.7.1.1.12 |
|
If the priority scheme is being used,
this value specifies a limit on how long
a station can transmit frames at access
class 2. The limit is measured from the
time the station is able to start
transmitting frames at this access
class on one rotation, to the time it
must stop transmitting frames at this
access class on the next rotation. If
the priority scheme is not being used,
this object has the value 0.
|
| dot4TargetRotTimeClass0 |
.1.3.6.1.3.7.1.1.13 |
|
If the priority scheme is being used,
this value specifies a limit on how long
a station can transmit frames at access
class 0. The limit is measured from the
time the station is able to start
transmitting frames at this access
class on one rotation, to the time it
must stop transmitting frames at this
access class on the next rotation. If
the priority scheme is not being used,
this object has the value 0.
|
| dot4TargetRotTimeRingMaint |
.1.3.6.1.3.7.1.1.14 |
|
A value used to limit the duration of a
token rotation. If the duration of a
token rotation exceeds this value, the
station will not open the response window
to solicit for a new successor.
|
| dot4RingMaintTimerInitValue |
.1.3.6.1.3.7.1.1.15 |
|
The value to which the
dot4TargetRotTimeRingMaint is set, each
time the station enters the ring.
A large value will cause the station to
solicit successors immediately upon entry
to the ring; a value of zero will cause
the station to defer this solicitation
for at least one token rotation.
|
| dot4MaxInterSolicitCount |
.1.3.6.1.3.7.1.1.16 |
|
The maximum number of consecutive token
rotations without soliciting for a
successor. If this count expires, the
station opens the response window to
solicit for a successor (providing the
duration of the current token rotation
has not exceeded
dot4TargetRotTimeRingMaint). The least
significant two bits of the count are
determined randomly by the station on a
per-use basis.
|
| dot4MaxRetries |
.1.3.6.1.3.7.1.1.17 |
|
The maximum number of retries of a
Request-with-Response (RWR) frame. If
the RWR option is not in use, this object
has the value 0.
|
| dot4MinPostSilencePreambLen |

|
The minimum number of octets of preamble
on the first frame transmitted by this
