Finding the Management Station on the Network

In the Ring Map window, the management station’s label is surrounded by a blue border 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 management station. The Find —> Management Station feature allows you to quickly identify the management station on the network. To ﬁnd the management station for the currently selected ring network:

1. Click on , and drag down to select Management Station.

The current ring management station will appear in the Ring Map window surrounded by a blue border, and the display will shift if necessary.

Finding the Last Beaconing Station

A beacon is an alert issued by a station when it detects a hardware failure on the network (because its incoming signal has been lost). Note that the station transmitting the beacon may not be the actual station experiencing a hardware failure (since the fault could lie with the NIC adapter of its upstream neighbor, with its own adapter, or with the cabling between the two stations).

The Find —> Last Beacon feature lets you determine which station on the network last issued beacon frames. To ﬁnd this station:

1.Click on , and drag down to select Last Beaconing Station. If no stations have beaconed since the map was invoked, a footer message will appear. A footer message will also appear if the last beaconing station is no longer on the ring.

Searching by Highest or Lowest Occurrence of a

Performance Parameter

You can use the Find By Highest and Find By Lowest features to search for a station by ascending (By Lowest –> Highest) or descending (By Highest –> Lowest) order of frames processed, total errors, or speciﬁc errors.
