	Token Ring Alarms
Token Errors	The threshold of errors requiring the management
	station (while acting as the active monitor) to transmit a
	token onto the monitored ring before it issues an alarm.
	The default value is 10.
Claim Token	The number of times that a claim token can be released
	by ring stations within the given time base before an
	alarm is triggered. A claim token is released by a ring
	station when it detects that the active monitor is absent
	or malfunctioning. Stations receiving the claim token will
	participate in the monitor contention process to
	determine a new active monitor. The default value is 5.
Lost Frame	The number of lost frames that the management station
	transmits onto the monitored ring before triggering an
	alarm. Lost frames are frames that do not return before
	the management station’s Timer Return to Repeat (TRR)
	timer expires. These can be caused by stations entering or
	leaving the ring during frame transmission. The default
	value is 10.
Frame Count	The number of frames that can be transmitted on the ring
	within the time base before the alarm limit is reached.
	For a network running at 16 Mbits/sec, the default value
	is 33,890. This number represents the maximum
	bandwidth used by 64 byte frames transmitted over the
	network during the default 10 second alarm time base.
	For a network running at 4 Mbits/sec, the default value
	is 18,920 (of 64 byte frames).
Beacon	The number of beacons that can be detected on the ring
	within the time base before the alarm limit is reached. A
	station transmits a beacon when its monitor contention
	timer expires, indicating that an Active Monitor could
	not be elected. Beaconing provides a method for the
	beaconing station and its NAUN to check their lobe
	wiring and to begin the monitor contention process if
	necessary. The default value is 1.

Ring-Level Station Alarms

When you set a ring-level station alarm (using the fields in the section of the window labeled Station Errors), the alarm threshold will be applied to all stations inserted into the currently monitored ring network. These values will override any pre-set station-level alarms, so these fields can be used to quickly apply one set of station-level alarm limits to all stations on the ring.
