Note
Click on Defaults to set the threshold settings to the default values. Under Usage in the context of the Throughput Usage threshold is a 'falling threshold'. Alarm is generated when the Throughput % drops below a certain value. This is helpful on very busy networks, where a certain amount of traffic is always expected to be seen. This type of alarm is a good indication that there is a communication problem on the network.
Note
Port Throughput Usaage metric is applicable at device level configuration but not at admin domain level.
