cienaCesOamMode
Module: CIENA-CES-OAM-MIB
OID (symbolic): CIENA-CES-OAM-MIB::cienaCesOamMode
OID (numeric): 1.3.6.1.4.1.1271.2.3.5.1.1.4.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This object indicates the mode of OAM operation for this Ethernet like interface. OAM on Ethernet interfaces may be in 'active' mode or 'passive' mode. These two modes differ in that active mode provides additional capabilities to initiate monitoring activities with the remote OAM peer entity, while passive mode generally waits for the peer to initiate OAM actions with it. As an example, an active OAM entity can put the remote OAM entity in a loopback state, where a passive OAM entity cannot.
The default value of cienaCesOamMode is dependent on the type of system on which this Ethernet like interface resides. The default value should be 'active(1)' unless it is known that this system should take on a subservient role to the other device connected over this interface.
If this values gets changed it value results in incrementing the configuration revision field of locally generated OAMPDUs (30.3.6.1.12) and potentially re-doing the OAM discovery process if the cienaCesOamOperStatus was already operational(9).
What is cienaCesOamMode?
This read-only INTEGER reports whether this interface's Ethernet OAM is operating in 'active' or 'passive' mode, per its description, where active mode can initiate monitoring activities like remote loopback with the peer while passive mode can only respond to them. This distinction matters because two passive-mode OAM entities cannot establish a session with each other, at least one side of a link must be active, so this value is a key input when diagnosing why OAM discovery never completes. An engineer connecting two devices for the first time would check both ends' mode settings to confirm at least one is configured active before assuming a cabling or hardware problem.
