Active Monitor
This area of the Token Ring DCE Ring Information view provides information
on the active monitor for this ring. This section provides the following fields:
Active Monitor
Displays the MAC address of the active monitor on this ring. If this address is
unknown, then the value is equal to six octets of zero.
Monitor Contentions
Displays the number of times the ring has entered the monitor contention
state from the normal ring state, or ring purge state. The monitor contention
state resulting from the ring leaving the beacon state is not counted.
Station Table
This area of the Token Ring DCE Ring Information view provides information
on the station table for this ring, including the maximum number, number of
active stations, and table changes. This section provides the following fields:
Max Stations
Displays the operational size of the station information table. This size is the
maximum number of stations for which information can be collected. A ring is
limited to a maximum number of 256 active stations. The station table can
also contain entries for inactive stations, resulting in a combination of active
and inactive stations. Any combination of inactive and active stations is
allowable, with the exception that the active stations must be fewer than the
SignalLoss The last beacon frame detected on the ring was a signal loss
beacon. This type of beacon frame is sent out by a station
which has ‘contention timeout’ and is participating in the
monitor contention process when it detects a signal loss.
BitStreaming The last beacon frame detected on the ring was a bit
streaming beacon. This type of beacon frame is sent out by a
station which has ‘monitor timeout’ and is participating in
the monitor contention process but does not receive any
claim token.
ContentionStreaming The last beacon frame detected on the ring was a contention
streaming beacon. This type of beacon frame is sent out by a
station which has monitor contention timeout expired, is
participating in the monitor contention process, and receives
multiple claim tokens and cannot solve the contention within
one second.
