ddmBiasCurThresholdLowAlarm

Module: TPLINK-DDMBIASCURTHRESHOLD-MIB

OID (symbolic): TPLINK-DDMBIASCURTHRESHOLD-MIB::ddmBiasCurThresholdLowAlarm

OID (numeric): 1.3.6.1.4.1.11863.6.96.1.4.1.1.3

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-write

Description: This object indicates the lowest threshold for the alarm.

What is ddmBiasCurThresholdLowAlarm?

This read-write string configures the lower alarm threshold for the transceiver's laser bias current, the point below which DDM triggers a low-alarm condition. It helps admins catch a failing or aging optical transceiver whose laser bias current has dropped too low to maintain a reliable optical signal. For example, setting this value to "2.0" means the switch raises a bias-current low alarm if the SFP's measured bias current falls under that level.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11863.6.96.1.4.1.1.3
snmpwalk -v2c -c public <target> TPLINK-DDMBIASCURTHRESHOLD-MIB::ddmBiasCurThresholdLowAlarm

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.11863.6.96.1.4.1.1.3.1
snmpget -v2c -c public <target> TPLINK-DDMBIASCURTHRESHOLD-MIB::ddmBiasCurThresholdLowAlarm.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.11863.6.96.1.4.1.1.3.1 s <value>
