Module: COMTROL-ES8510-MIB
OID (symbolic): COMTROL-ES8510-MIB::portSfpDdmRxPowerCurrent
OID (numeric): 1.3.6.1.4.1.2882.2.1.1.3.2.2.1.9
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-only
Description: The current SFP Receiveed Power of port.
What is portSfpDdmRxPowerCurrent?
This read-only value reports the SFP transceiver's current optical receive power level, as measured by the module's digital diagnostic monitoring (DDM) circuitry. An admin watching this on a fiber uplink can catch a slowly degrading connector, bend, or aging laser before the link drops entirely, since receive power typically falls gradually rather than failing instantly. For example, seeing the reading slide from -8 dBm to -20 dBm over a few weeks on a fiber uplink port signals a failing SFP that should be scheduled for replacement.
