cmEthernetNetPortHistoryLBC
Module: CM-PERFORMANCE-MIB
OID (symbolic): CM-PERFORMANCE-MIB::cmEthernetNetPortHistoryLBC
OID (numeric): 1.3.6.1.4.1.2544.1.12.5.1.6.1.32
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Laser Bias Current (in mA) for the physical layer. This is applicable only if the media type for the Network Port is fiber.
What is cmEthernetNetPortHistoryLBC?
This Integer32 value is the laser bias current of the port in mA, applicable only when the port media is fiber. An admin watches it because laser bias current climbing over time as an optical transmitter ages is a classic leading indicator that the module is near end of life. Seeing cmEthernetNetPortHistoryLBC on network (uplink) port 13 creep up to 40 mA at the most recent completed bin, well above its value from a few weeks earlier, tells an operator to proactively order a replacement optic.
