B2TCA: The RX detects b2(B2) threshold(T) crossing(C) alarm(A). B3TCA: The RX detects b3(B3) threshold(T) crossing(C) alarm(A). LAIS: The RX detects line(L) alarm(A) indication(I) signal(S). LCD: The RX detects loss(L) of code-group(C) delineation(D). LOF: The RX detects loss(L) of(O) frame(F). LOM: The RX detects loss(L) of(O) multiframe(M). LOP: The RX detects loss(L) of(O) pointer(M). LOS: The RX detects loss(L) of(O) signal(S). LRDI: The RX detects line(L) remote(R) defect(D) indication(I). LREI: The RX detects line(L) remote(R) error(D) indication(I). OOF: The RX detects out(O) of(O) frame(F). PAIS: The RX detects path(P) alarm(A) indication(I) signal(S). PPLM: The RX detects path(P) payload(P) label(L) mismatch(M). PRDI: The RX detects path(P) remote(R) defect(D) indication(I). PREI: The RX detects path(P) remote(R) error(E) indication(I). PUNEQ: The RX detects path(P) unequipped(UNEQ). RDOOL: The RX detects receive(R) data(D) out(O) of(O) lock(L). RROOL: The RX detects receive(R) reference(R) out(O) of(O) lock(L). SD: The RX detects signal(S) degrade(D). SF: The RX detects signal(S) fail(F). TROOL: The TX detects transmit(T) reference(R) out(O) of(O) lock(L). WLINK: The RX detects pcs link has failed (wis mode). TRANSCEIVER_OFFLINE: The transceiver is not in position. TRANSCEIVER_FAIL: A hardware failure occurs when accessing the transceiver. TRANSCEIVER_MISMATCH: The transceiver does not match the port-mode. TRANSCEIVER_UNKNOWN: The transceiver is unknown type. PMA_LOS: The PMA(physical medium attachment) detects loss of signal. PMA_UNLOCK: The PMA(physical medium attachment) detects receive data out of lock. PCS_HIGHBER: The PCS(physical coding sublayer) enter High-BER status. PCS_UNLOCK: The PCS(physical coding sublayer) detects receive data out of lock. LOCAL_FAULT: The RX detects Local Fault signal. REMOTE_FAULT: The RX detects Remote Fault signal. NEGOTIATION_FAIL: Auto-negotiation is not successful. SOFT_FORCE_DOWN: The interface was DOWN triggered by a protocol module or was administratively shut down.

What is hwPortPhysicalDownReason?

Carries a coded reason string (e.g. AUAIS, B1TCA, LAIS, LCD) explaining why a physical port went down, sent as a varbind on the port-down trap so an operator can immediately see the specific SDH/optical alarm condition that caused the outage instead of just 'link down'.
