h3cDot3OamUnsupportedCodesTx
Module: A3COM-HUAWEI-EFM-COMMON-MIB
OID (symbolic): A3COM-HUAWEI-EFM-COMMON-MIB::h3cDot3OamUnsupportedCodesTx
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.42.3.1.4.1.15
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 opcode 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 equals the opcode 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 h3cDot3OamUnsupportedCodesTx?
This Counter32 tracks OAM messages with unsupported operation codes transmitted from the interface. A non-zero count alerts engineers to compatibility issues with the OAM implementation or peer device. Seeing 5 unsupported codes suggests occasional out-of-spec requests being sent.
