Module: NBS-EFM-MIB

OID (symbolic): NBS-EFM-MIB::nbsEfmOamUnsupportedCodesRx

OID (numeric): 1.3.6.1.4.1.629.300.1.3.1.1.14

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: A count of OAMPDUs received that contain an OAM code from Table 57-4 that are not supported by the device. This counter is incremented on reception of a valid frame with (1) destinationField equal to the reserved multicast address for Slow_Protocols specified in CROSS REF Table 43B-1, (2) lengthOrType field value equal to the reserved Type for Slow_Protocols as specified in CROSS REF Table 43B-2, (3) a Slow_Protocols subtype value equal to the subtype reserved for OAM as specified in Table 43B-3, (4) an OAM code for a function that is not supported by the device.

What is nbsEfmOamUnsupportedCodesRx?

This OID counts received OAMPDUs whose OAM code (per IEEE 802.3ah Table 57-4) is not supported by this device. An admin watches this to detect an interoperability mismatch where the remote peer is sending OAM functions the local device can't process.
