cienaCesOamUnsupportedCodesTx
Module: CIENA-CES-OAM-MIB
OID (symbolic): CIENA-CES-OAM-MIB::cienaCesOamUnsupportedCodesTx
OID (numeric): 1.3.6.1.4.1.1271.2.3.5.1.1.1.1.13
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: A count of the number of OAMPDUs transmitted on this interface with an unsupported op-code.
An unsupported op-code 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 op-code for a function that is not supported by the device.
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 cienaCesOamUnsupportedCodesTx?
This Counter32 (frames) counts OAMPDUs transmitted on this interface with an unsupported op-code, per its description, an unusual and generally undesirable condition since the local device itself is generating the frame. An incrementing value here would point to a software defect or an unexpected OAM configuration on the local device rather than anything the link partner did. An engineer seeing this counter increase would treat it as a local-device bug report rather than a link-quality issue, since it reflects OAMPDUs this box itself sent with a code it shouldn't be using.
