ddmVolThresholdHighAlarm

Module: TPLINK-DDMVOLTHRESHOLD-MIB

OID (symbolic): TPLINK-DDMVOLTHRESHOLD-MIB::ddmVolThresholdHighAlarm

OID (numeric): 1.3.6.1.4.1.11863.6.96.1.3.1.1.2

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-write

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

What is ddmVolThresholdHighAlarm?

This read-write object sets the highest supply-voltage value, before an alarm is raised, for the transceiver's Digital Diagnostic Monitoring (DDM) on this port. Admins configure this threshold so the switch flags a transceiver whose measured voltage climbs dangerously high, which can indicate a failing or out-of-spec optic. Setting ddmVolThresholdHighAlarm to "3.63" (volts) on a port causes an alarm once that transceiver's supply voltage exceeds 3.63V.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11863.6.96.1.3.1.1.2
snmpwalk -v2c -c public <target> TPLINK-DDMVOLTHRESHOLD-MIB::ddmVolThresholdHighAlarm

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.11863.6.96.1.3.1.1.2.1
snmpget -v2c -c public <target> TPLINK-DDMVOLTHRESHOLD-MIB::ddmVolThresholdHighAlarm.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.11863.6.96.1.3.1.1.2.1 s <value>
