| dot5IfIndex |
.1.3.6.1.2.1.10.9.1.1.1 |
|
The value of this object identifies the
802.5 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 MIB-II for
the same interface.
|
| dot5Commands |
.1.3.6.1.2.1.10.9.1.1.2 |
|
When this object is set to the value of
open(2), the station should go into the
open state. The progress and success of
the open is given by the values of the
objects dot5RingState and
dot5RingOpenStatus.
When this object is set to the value
of reset(3), then the station should do
a reset. On a reset, all MIB counters
should retain their values, if possible.
Other side affects are dependent on the
hardware chip set.
When this object is set to the value
of close(4), the station should go into
the stopped state by removing itself
from the ring.
Setting this object to a value of
noop(1) has no effect.
When read, this object always has a
value of noop(1).
The open(2) and close(4) values
correspond to the up(1) and down(2) values
of MIB-II's ifAdminStatus and ifOperStatus,
i.e., the setting of ifAdminStatus and
dot5Commands affects the values of both
dot5Commands and ifOperStatus.
|
| dot5RingStatus |
.1.3.6.1.2.1.10.9.1.1.3 |
|
The current interface status which can
be used to diagnose fluctuating problems
that can occur on token rings, after a
station has successfully been added to
the ring.
Before an open is completed, this
object has the value for the 'no status'
condition. The dot5RingState and
dot5RingOpenStatus objects provide for
debugging problems when the station
can not even enter the ring.
The object's value is a sum of
values, one for each currently applicable
condition. The following values are
defined for various conditions:
0 = No Problems detected
32 = Ring Recovery
64 = Single Station
256 = Remove Received
512 = reserved
1024 = Auto-Removal Error
2048 = Lobe Wire Fault
4096 = Transmit Beacon
8192 = Soft Error
16384 = Hard Error
32768 = Signal Loss
131072 = no status, open not completed.

recent attempt to enter the ring.

given by MIB-II's ifSpeed. For interfaces
which do not support changing ring-speed,
dot5RingSpeed can only be set to its current
value. When dot5RingSpeed has the value
unknown(1), the ring's actual ring-speed is
to be used.

this interface will participate in the

value is false(2) then it will not.
Setting this object does not take effect
until the next Active Monitor election, and
might not take effect until the next time
the interface is opened.
