cienaCesOamVariableRequestRx
Module: CIENA-CES-OAM-MIB
OID (symbolic): CIENA-CES-OAM-MIB::cienaCesOamVariableRequestRx
OID (numeric): 1.3.6.1.4.1.1271.2.3.5.1.1.1.1.8
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: A count of the number of Variable Request OAMPDUs received on this interface. An Variable Request OAMPDU is indicated by a valid frame with (1) destination MAC address equal to that of the reserved MAC address for Slow Protocols (See 43B of [802.3ah]), (2) a lengthOrType field equal to the reserved type for Slow Protocols, (3) a Slow Protocols subtype equal to that of the subtype reserved for OAM, and (4) an OAMPDU code equal to the OAM Variable Request code.
Discontinuities of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of the ifCounterDiscontinuityTime.
What is cienaCesOamVariableRequestRx?
This Counter32 (frames) counts Variable Request OAMPDUs received on this interface, per its description, meaning the peer is asking this device to report specific monitored-variable values over the OAM channel. Because variable retrieval is optional per 802.3ah, an incrementing value here confirms the peer device actually supports and is exercising this OAM function against the local device, not just basic discovery. A technician debugging why a remote NMS can't retrieve certain OAM variables would check whether requests are even arriving here, which this counter answers directly.
