nbsEfmOamCfg

Module: NBS-EFM-MIB

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

OID (numeric): 1.3.6.1.4.1.629.300.1.3.1.1.5

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-only

Description: A string of three bits corresponding to the OAM Configuration field (see Table 57-7) in the most recently received Information OAMPDU. The first bit corresponds to the OAM Mode bit in the OAM Configuration field. The second bit corresponds to the Unidirectional Support bit in the OAM Configuration field. The third bit corresponds to the Loopback Support bit in the OAM Configuration field. This value is updated 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) the OAM code equals the OAM Information code.

What is nbsEfmOamCfg?

This OID reports a three-bit string from the OAM Configuration field of the most recently received Information OAMPDU, covering the OAM Mode, Unidirectional Support, and Loopback Support bits per IEEE 802.3ah Table 57-7. An admin decodes this to see what OAM capabilities the remote peer has advertised.
