Module: SNMP540-ALARM-MIB
OID (symbolic): SNMP540-ALARM-MIB::threshold
OID (numeric): 1.3.6.1.4.1.498.8.4.10.5.1.6
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This function sets/reads the alarm threshold 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 threshold?
This object sets or reads the alarm threshold criteria, used together with the alarm window to determine how many instances within a timeframe must occur before the alarm becomes active; documented example ranges include 0-99% for Jitter, counts for BPV and Frame Loss, and -50 to 6dB for Rx Level Low. Admins tune it per alarm type to match the sensitivity appropriate for that fault condition. Setting the threshold for the Rx Level Low alarm to -30dB, its documented default, means the alarm activates once received signal level drops below that point.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.498.8.4.10.5.1.6 snmpwalk -v2c -c public <target> SNMP540-ALARM-MIB::threshold
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.498.8.4.10.5.1.6.1 snmpget -v2c -c public <target> SNMP540-ALARM-MIB::threshold.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.498.8.4.10.5.1.6.1 i <value>
