Threshold
This menu displays the current alarms that are set and allows alarms to
be added or modified.
Alarms can help you locate problems or faults on the network. When
you set an alarm threshold for an activity on a hub, you instruct the hub
to take a specific action when the value falls above or below the set
threshold.
Table 4-11 describes each field in the Threshold menu.
∆ Note: For instructions on using this menu, see “Setting
Alarms” on page 3-24.
