show ethernet_oam ports (status)
• SendLocalAndRemoteOk: The local device agrees the OAM peer entity.
• PeeringLocallyRejected: The local OAM entity rejects the remote peer OAM entity.
• PeeringRemotelyRejected: The remote OAM entity rejects the local device.
• Operational: The local OAM entity learns that both it and the remote OAM entity
have accepted the peering.
• NonOperHalfDuplex: Since Ethernet OAM functions are not designed to work
completely over half-duplex port. This value indicates Ethernet OAM is enabled but
the port is in half-duplex operation.
(3) OAM mode: passive or active
(4) Maximum OAMPDU size: The largest OAMPDU that the OAM entity supports. OAM
entities exchange maximum OAMPDU sizes and negotiate to use the smaller of the two
maximum OAMPDU sizes between the peers.
(5) OAM configuration revision: The configuration revision of the OAM entity as reflected
in the latest OAMPDU sent by the OAM entity. The config revision is used by OAM
entities to indicate that configuration changes have occurred, which might require the
peer OAM entity to re-evaluate whether OAM peering is allowed.
(6) OAM Functions Supported: The OAM functions supported on this port. These
functions include:
• Unidirectional: It indicates that the OAM entity supports the transmission of
OAMPDUs on links that are operating in unidirectional mode (traffic flowing in one
direction only).
• Loopback: It indicates that the OAM entity can initiate and respond to loopback
commands.
• Link Monitoring: It indicates that the OAM entity can send and receive Event
Notification OAMPDUs.
• Variable: It indicates that the OAM entity can send and receive variable requests to
monitor the attribute value as described in the IEEE 802.3 Clause 30 MIB
(7) Loopback Status: The current status of the loopback function of the port:
• No Loopback – The local and remote ports are not in loopback mode.
• Initiating Loopback – The local port has sent the start remote loopback request to
the peer and is waiting for response.
• Remote Loopback – This indicates that both the local and remote ports entered the
loopback mode. Any non-OAM packet received in the local port will be dropped.
• Local Loopback – This indicates that both the local and remote ports entered the
loopback mode. The local port is doing the loopback. Any non-OAM packets
received on the port will be sent back to the same port.
• Terminate Loopback - The port is stopping loopback on the port.
Parameters
<portlist> - Specifies a range of ports to display status.
