4-2 ATX MIB Reference Guide
dot5Commands {dot5Entry 2}
Integer Read-Write
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 no-op(1) has no effect. When read, this object always has a
value of no-op(1).
dot5RingStatus {dot5Entry 3}
Integer Read-Only
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
• 16348 = Hard Error
• 32768 = Signal Loss
• 131072 = no status, open not completed
