Configuration Notes and Constraints

When configuring EFM OAM, pay attention to the following notes:

• An EFM connection cannot be established between two EFM OAM entities that are both in passive mode.

• Only the active mode end canrun commands ethernet-oam remote-loopback start interface <interface-name> or ethernet-oam remote-loopback stop interface <interface-name> to start | stop EFM OAM remote loopback tests.

• Before starting the EFM OAM remote loopback tests, make sure:

  • The EFM OAM connection has been established successfully.

  • Users have to configure command set protocols ethernet-oam interface <interface-name> remote-loopback supported on the responding end to enable reactions to loopback control OAMPDUs from peers.

• Remote loopback cannot be configured on the same port as the loopback of the physical port.
