Viewing Beacon History

The Beacon History window displays a record of signiﬁcant ring events, including active monitor changes, ring purges, and information related to beaconing states. The information displayed in this window will update after each polling interval.

To open the Beacon History window:

1.Click on at the top of the Ring Map window.

2.Drag down to Beacon History, and release. The Beacon History window, Figure 3-11, will appear.

Figure 3-11. The Beacon History Window

The Beacon History window contains the following information:

Active Monitor Changes

Displays the number of times the ring’s active monitor has changed since the ring was ﬁrst initialized or the device was last reset.

Ring Purges

Displays the number of times the active monitor has purged the ring. This includes the purge at the end of the active monitor selection process.

Note that this count is not reset when the active monitor changes.

Beacon Events

This ﬁeld detects the number of beaconing occurrences detected by the active monitor on the ring. A beacon is transmitted when a hardware error — such as a wire fault, frequency error, or ring signal loss — is detected on the ring, and when monitor contention times out.
