Description:
Laser Bias Current (in mA) for the physical layer. This is applicable only if the media type for the Access Port is fiber.
What is cmEthernetAccPortHistoryLBC?
This metric records the laser bias current (in milliamps) for fiber optic transmission on an access port. The bias current indicates how hard the laser is working and serves as a health indicator for optical modules. Operators check this to detect laser aging or power supply issues before the interface fails.
