This object configures the mode of OAM operation for this 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 OA actions with it. Changing this value results in incrementing the configuration revision field of locally generated OAMPDUs and potentially re-doing the OAM discovery process if the asDot3OamPortStatus was already operational(9).
