What is oaSfpDiagnosticTxBias?

This reports the transceiver's internally measured laser transmit bias current in microamps. A rising bias current over time typically signals laser aging, so admins track this value to predict when an optic will need replacing.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.6926.1.18.1.1.3.1.5
snmpwalk -v2c -c public <target> OA-SFP-MIB::oaSfpDiagnosticTxBias

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.6926.1.18.1.1.3.1.5.1
snmpget -v2c -c public <target> OA-SFP-MIB::oaSfpDiagnosticTxBias.1
