Searching for the Active Monitor, Ring Management Station,
or Last Beaconing Station
Find Active Monitor, Find Management Station, and Find Last Beacon allow you
to quickly discover the ring network’s active monitor and its ring management
station, as well as the last station reporting a hardware failure.
Finding the Active Monitor on the Network
The Active Monitor is the station responsible for setting timing functions for the
ring, activating hardware to remove an improperly circulating frame or token,
purging the ring to restore it to normal condition, and starting the ring poll
process, among other duties.
In the Ring Map window, its label is displayed in green to differentiate it from
other stations. However, in a ring network with many stations, it may be
inconvenient to scroll through the map to find the Active Monitor. The Find —>
Active Monitor
feature allows you to quickly identify the Active Monitor on the
network. To find the Active Monitor for the currently selected ring network:
1. Click on , and drag down to select Active Monitor.
The current active monitor will appear highlighted in the Ring Map window, and
the display will shift if necessary.
