hh3cDot3OamUnsupportedCodesRx

Module: HH3C-EFM-COMMON-MIB

OID (symbolic): HH3C-EFM-COMMON-MIB::hh3cDot3OamUnsupportedCodesRx

OID (numeric): 1.3.6.1.4.1.25506.2.42.3.1.4.1.16

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 hh3cDot3OamUnsupportedCodesRx?

A running count of OAMPDUs received on this interface carrying an OAM op-code this device doesn't support. A nonzero and rising value suggests the peer is using OAM features this device's implementation doesn't recognize, worth checking for a firmware or feature-support mismatch.
