Used to show primary controls and status information for Ethernet OAM.
show ethernet_oam ports {<portlist>} status
This command is used to show primary controls and status information for Ethernet OAM on
specified ports.
The information includes:
(1) OAM administration status: enabled or disabled
(2) OAM operation status. See below values:
Disable: OAM is disabled on this port
LinkFault: The link has detected a fault and is transmitting OAMPDUs with a link fault
indication.
PassiveWait: The port is passive and is waiting to see if the peer device is OAM capable.
ActiveSendLocal: The port is active and is sending local information
SendLocalAndRemote: The local port has discovered the peer but has not yet accepted or
rejected the configuration of the peer.
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 ports. 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 loop-back 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
At present, only unidirectional, loop-back and link monitoring are supported.
portlist – Specifies a range of ports to display.
Only Administrator and Operator-level users can issue this command.
