Parameters

local: Displays local Ethernet OAM connection information.

remote: Displays remote Ethernet OAM connection information.

interface interface-type interface-number: Specifies a port by its type and number.

|: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide.

begin: Displays the first line that matches the specified regular expression and all lines that follow.

exclude: Displays all lines that do not match the specified regular expression.

include: Displays all lines that match the specified regular expression.

regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.

Description

Use display oam to display information about an Ethernet OAM connection, including connection status, information contained in the Ethernet OAM packet header, and Ethernet OAM packet statistics.

If no interface is specified, this command displays information about all Ethernet OAM connections.

Related commands: reset oam.

Field	Description
Port	Port index.
Link Status	Link status (up or down).
EnableStatus	Ethernet OAM state (enabled or disabled).
Local_oam_mode	Local Ethernet OAM mode: Active—The port is operating in active Ethernet OAM mode. Passive—The port is operating in passive Ethernet OAM mode.
Local_pdu	The way in which the local end processes Ethernet OAMPDUs: RX_INFO—The port only receives Information OAMPDUs and does not send any Ethernet OAMPDUs. LF_INFO—The port only sends the Information OAMPDUs without Information TLV triplets and with their link error flag bits being set. INFO—The port sends and receives only Information OAMPDUs. ANY—The port sends and receives Ethernet OAMPDUs of any type.
Local_mux_action	Working mode of the local transmitter: FWD—The port can send any packets. DISCARD—The port only sends Ethernet OAMPDUs.
Local_par_action	Working mode of the local receiver: FWD—The port can receive any packets. DISCARD—The port only receives Ethernet OAMPDUs. LB—The local receiver is in loopback state. All the packets other than Ethernet OAMPDUs received on the local receiver are returned to their sources along the ways they came.
OAMLocalFlagsField	Local flags inserted in the local flag fields of the Ethernet OAMPDUs sent.
Link Fault	Indicates whether an Ethernet OAM link error is present: 0 for no and 1 for yes.
Dying Gasp	Indicates whether a fatal error is present: 0 for no and 1 for yes.
Critical Event	Indicates whether a critical error is present: 0 for no and 1 for yes.
Local Evaluating	Indicates whether the local-to-remote configuration negotiation is complete: COMPLETE—The negotiation is completed. NOTCOMPLETE—The negotiation is uncompleted.
Remote Evaluating	Indicates whether the remote-to-local configuration negotiation is complete: COMPLETE—The negotiation is completed. NOTCOMPLETE—The negotiation is uncompleted. RESERVED—The field is reserved and the negotiation is uncompleted. UNSATISFIED—The peer end is not satisfied with the local configuration and the negotiation is uncompleted.
Packets statistic	Statistics for Ethernet OAMPDUs sent and received.
OAMPDU	Total number of the Ethernet OAMPDUs sent and received.
OAMInformation	Number of Information OAMPDUs sent and received.
OAMEventNotification	Number of Event notification OAMPDUs sent and received.
OAMUniqueEventNotification	Number of unduplicated Event notification OAMPDUs sent or received.
OAMDuplicateEventNotification	Number of duplicate Event notification OAMPDUs sent or received.
