opticalPortRxSignalState
Module: PORT-MIB
OID (symbolic): PORT-MIB::opticalPortRxSignalState
OID (numeric): 1.3.6.1.4.1.5812.3.7.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Provides the status of the received optical signal - whether it is detected or not.
What is opticalPortRxSignalState?
This reports whether the received optical signal is currently detected or has a loss of signal condition. An admin uses this as a first-line check when troubleshooting a suspected fiber, connector, or transceiver problem, since a lossOfSignal reading typically points to a physical-layer issue upstream of the framer logic. It's a simpler, lower-level indicator than opticalPortRxFrameState, which checks whether the signal is properly framed.
