trk Un Acked Framer Critical Link Utilization Alarm Threshold
1.3.6.1.4.1.562.2.4.1.60.2.2.15.1.3
This attribute provides the threshold value which defines when a critical alarm would be issued, denoting a sustained total average link utilization. The total average link utilization is calculated based on the number of received bytes. The Set alarm is issued after 3 minutes of utilization greater than the given threshold. The corresponding Clear alarm is issued after a subsequent 3 minutes of utilization less than or equal to the given threshold. The value 100% is used to disable an individual threshold. For values other than 100%, a semantic check ensures that the critical alarm threshold is greater than the other thresholds.
