We reproduced the IfErrorStatus condition by simply raising the rate of the ifInErrors variable (as described above) to 20% of the traffic. We reproduced the IfLoad condition by raising the rate of the ifOutUcastPkts object, which had a relationship with the ifOutOctets object (with an average packet size of 1000, the rate of outgoing octets is 1000 times the rate of outgoing packets).

Note that it took NerveCenter 3 minutes to discover the load condition of device as shown in the "High Alarms" screen. The rate of the ifNOutUcastPkts object was significantly raised (from 100 to 1000) around 16:46:57 as shown in the traffic graph, and this condition was detected by NerveCenter at 16:50:39.
