swDdmLowAlarm

Module: DDM-MGMT-MIB

OID (symbolic): DDM-MGMT-MIB::swDdmLowAlarm

OID (numeric): 1.3.6.1.4.1.171.12.72.3.1.1.1.3

Node type: OBJECT-TYPE

Type: DisplayString

Access: read-write

Description: This object indicates the low alarm threshold value to be configured. As the value is a floating data type, the DisplayString type is used to define this parameter.

What is swDdmLowAlarm?

This read-write value sets the low alarm threshold for whichever DDM parameter the row's swDdmThresholdType identifies, encoded as a DisplayString because the value is a floating-point number. An admin lowers this threshold for older, marginal optics to avoid alarm floods while still catching a genuine failure. For example, setting swDdmLowAlarm to "-30.0" on an rxPower row raises an alarm only once receive power sinks below that dBm floor.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.72.3.1.1.1.3
snmpwalk -v2c -c public <target> DDM-MGMT-MIB::swDdmLowAlarm

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.72.3.1.1.1.3.1
snmpget -v2c -c public <target> DDM-MGMT-MIB::swDdmLowAlarm.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.171.12.72.3.1.1.1.3.1 s <value>
