dot3OamUnsupportedCodesRx
Module: EFM-COMMON-MIB
OID (symbolic): EFM-COMMON-MIB::dot3OamUnsupportedCodesRx
OID (numeric): 1.3.6.1.2.1.9908.1.4.1.16
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: A count of the number of OAMPDUs received 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 dot3OamUnsupportedCodesRx?
A count of OAM PDUs received on this interface carrying an opcode this device doesn't support — a rising count here usually means the peer supports OAM functions (like loopback or event notifications) that this device can't process.
