Ring Map
3-28 Using the Find Options
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.
