Module: COMTROL-ES8510-MIB
OID (symbolic): COMTROL-ES8510-MIB::portSfpDdmTxPowerCurrent
OID (numeric): 1.3.6.1.4.1.2882.2.1.1.3.2.2.1.7
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-only
Description: The current SFP Transmitted Power of port.
What is portSfpDdmTxPowerCurrent?
This read-only string reports the current optical transmit power level being output by the SFP module in a given port. A transmit power reading that drifts significantly from its expected baseline can indicate a degrading laser diode, giving the admin advance warning before the link actually fails. For example, if this value gradually declines over several weeks on a specific fiber uplink, the admin might proactively schedule that transceiver for replacement before it drops out of spec entirely.
