cienaCesOamPeerConfigRevision
Module: CIENA-CES-OAM-MIB
OID (symbolic): CIENA-CES-OAM-MIB::cienaCesOamPeerConfigRevision
OID (numeric): 1.3.6.1.4.1.1271.2.3.5.1.1.5.1.8
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: The configuration revision of the OAM peer as reflected in the latest OAMPDU. This attribute is changed by the peer whenever it has a local configuration change for Ethernet OAM this interface. This value is initialized to zero, and is invalid if the cienaCesOamPeerStatus is inactive.
The configuration revision can be determined from the Revision field of the Local Information TLV of the most recently received Information OAMPDU with a Local Information TLV.
An Information 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 OAM code that equals the code reserved for Information OAMPDUs.
What is cienaCesOamPeerConfigRevision?
This read-only Unsigned32 tracks the OAM configuration revision most recently reported by the peer in its OAMPDUs, per its description, changed by the peer whenever it has a local configuration change affecting Ethernet OAM on that interface, and invalid, reading zero, whenever the peer status is inactive. This is the mirror image of the local device's own cienaCesOamConfigRevision, letting an engineer see when the remote end last altered its OAM configuration without needing access to that device. An engineer noticing an unexplained local OAM session behavior change would check whether this peer config revision incremented around the same time, pointing at a remote-side configuration change as the cause.
