Device Topology

•Threshold—the value of the event at which the trap or alarm is triggered

•Tolerance—the device does not send another event to the manager until the value goes below the tolerance value and the threshold value is reached again. The default is 80% of the threshold value.

•Time Interval—the time elapsed while HP TopTools examines speci- fied traffic for threshold and tolerance violations. If the threshold is reached with the time interval specified, an event is triggered.

3.Select the Trap Receivers tab and set the management stations that should receive traps.

4.Select the Authorized Managers tab and set the management stations that can send and receive SNMP requests for the device.

Device Topology

The Topology view displays a hierarchical representation of your network device connections. If HP TopTools is not able to associate a device with a segment, the device is listed as unmapped.
