This read-only CmOamMode object reports whether the remote EFM OAM peer on an Ethernet Network Port is operating in Active or Passive mode. It matters because knowing the remote's mode explains OAM session establishment behavior; a passive remote will never itself initiate discovery, relying entirely on this local port being Active. For example, if OAM never establishes on a new circuit, an admin would check cmEthernetNetPortOamRemoteMode to confirm whether the remote is passive and therefore relies on this local port being configured Active.
