ddmVolThresholdLowAlarm
Module: TPLINK-DDMVOLTHRESHOLD-MIB
OID (symbolic): TPLINK-DDMVOLTHRESHOLD-MIB::ddmVolThresholdLowAlarm
OID (numeric): 1.3.6.1.4.1.11863.6.96.1.3.1.1.3
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: This object indicates the lowest threshold for the alarm.
What is ddmVolThresholdLowAlarm?
This read-write object sets the lowest supply-voltage value, before an alarm is raised, for the transceiver's DDM on this port. Admins configure this threshold so the switch flags a transceiver whose supply voltage has dropped too low, a common early sign of a failing optic or power issue. Setting ddmVolThresholdLowAlarm to "2.97" (volts) on a port triggers an alarm if that transceiver's supply voltage falls below 2.97V.
