irSysTempHysteresis
Module: MRV-IR-SYSTEM-MIB
OID (symbolic): MRV-IR-SYSTEM-MIB::irSysTempHysteresis
OID (numeric): 1.3.6.1.4.1.33.100.1.1.18
Node type: OBJECT-TYPE
Type: INTEGER

Description: The hysteresis setting applied to the temp thresholds for the device.
What is irSysTempHysteresis?
This OID stores a text setting that controls temperature alarm sensitivity on the device. It defines how much the temperature must change before alarms switch on or off—preventing false alarms from small temperature fluctuations near the threshold. A network operator would adjust this value when the device generates too many temperature warnings due to minor environmental variations.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.33.100.1.1.18 snmpwalk -v2c -c public <target> MRV-IR-SYSTEM-MIB::irSysTempHysteresis
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.33.100.1.1.18.1 snmpget -v2c -c public <target> MRV-IR-SYSTEM-MIB::irSysTempHysteresis.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.33.100.1.1.18.1 i <value>
