Description: This function sets/reads the alarm threashold settings criteria.
        This threshold is used along with the alarm window to determine
        the number of instances in a given time frame for an alarm to 
        occur before the alarm is considered active.

What is nms520AlarmCfgThreshold?

Sets the threshold value (-50 to 99) that, combined with the alarm count window, determines when an alarm becomes active; for example the default is 9% for jitter, 10 counts for bipolar violations and frame loss, 0 for signal-to-noise ratio, and -33 dB for low receive signal.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.498.8.2.8.1.3
snmpwalk -v2c -c public <target> NMS520-MIB::nms520AlarmCfgThreshold

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.498.8.2.8.1.3.1
snmpget -v2c -c public <target> NMS520-MIB::nms520AlarmCfgThreshold.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.498.8.2.8.1.3.1 i <value>
