This section provides the following fields:
Ring Number
Displays the number identifying the ring being monitored by this DCE. Each
ring in a multiple ring network is assigned a unique number. Together, a ring
and bridge number form a route designator. The ring number is obtained by
the NMM during the initialization process.
Ring State
Displays the current status of the ring. Table 5-3 provides definitions of the
possible ring states.
Ring Purges
Displays the total number of times that the ring has entered the ring purge
state from the normal ring state. The ring purge state resulting from the ring
leaving the monitor contention or beacon state is not counted.
NAUN Changes
Displays the total number of NAUN changes that have been measured on the
Table 5-3. Ring Status Definitions
Ring Status Definition
NormalOperation The ring is operating without any interruptions.
RingPurge The ring is in its purge state. The active monitor enters
this state whenever a token error is detected.
MonitorContention The ring is in the monitor contention state. The ring
enters this state whenever the stations on the ring need
to establish an active monitor.
BeaconFrameStreaming The ring is in the beacon frame streaming state. The ring
enters this state when a station participating in the
monitor contention process, and has its monitor
contention timeout expired, receives multiple claim
tokens and cannot solve the contention within one
second.
BeaconBitStreaming The ring is in the beacon bit streaming state. The ring
enters this state when a station participating in the
monitor contention process, and has ‘monitor timeout,’
has not received any claim token.
BeaconRingSignalLoss The ring is in the beacon ring signal loss state. The ring
enters this state when a station participating in the
monitor contention process, and has ‘contention timeout,’
detects a signal loss.
BeaconSetRecoveryMode The ring is in the beacon set recovery mode. The ring
enters this state when a station, before acting as a
recovery station, sends out a beacon frame with a
recovery mode bit set.
