physicalPortCapLoopConfig
Module: ADVA-FSPR7-CAP-MIB
OID (symbolic): ADVA-FSPR7-CAP-MIB::physicalPortCapLoopConfig
OID (numeric): 1.3.6.1.4.1.2544.1.11.9.3.4.1.1.26
Node type: OBJECT-TYPE
Type: LoopConfigCaps
Access: read-only
Description: The configuration of the loopback function. - noLoop: no loop configuration on the interface. - lineLoop: the incoming signal is looped to the outgoing line on the interface. The incoming signal is sent in the downstream direction and processed as normal. - inwardLoop: the output signal is looped to the incoming line on the interface. The looped signal is transmitted unchanged on the optical output.
What is physicalPortCapLoopConfig?
This OID stores the supported loopback modes: no loopback, line loopback (signal returns through the outgoing path), or inward loopback (output signal loops back to incoming path). Network engineers use loopback testing to isolate port faults; knowing which modes are supported determines whether the port can perform self-diagnostics. For example, 'lineLoop' mode lets you send a test signal that exits the port and re-enters it immediately, validating the entire transmit-receive path.
