The display efm command displays EFM OAM configurations on a specified interface or all interfaces.
Parameter | Description | Value |
---|---|---|
all |
Displays EFM OAM configurations on all interfaces. |
- |
interface interface-type interface-number |
Displays EFM OAM configurations on a specified interface. |
interface-type specifies the type of an interface, which can be Ethernet or GE. interface-number specifies the number of an interface. |
The actual command output varies according to the device. The command output here is only an example.

EFM Enable Flag | Whether EFM OAM is enabled on the interface:
If the value of the EFM Enable Flag field is disable, run the efm enable command in the system view and interface view to enable EFM. |
Loopback IgnoreRequest | Whether the local interface ignores loopback requests. |
OAMPDU MaxSize | Maximum size of an OAM PDU on the interface. |
OAMPDU Interval | Interval at which OAM PDUs are sent on the interface. |
OAMPDU Timeout | Timeout period for waiting for OAM PDUs on the interface. |
Hold Up Time | Delay in changing the EFM OAM protocol status of the interface from Down to Up after a link connectivity fault is rectified. never indicates that the interface's EFM OAM protocol blocking status will never change to Up. |
Remote MAC | MAC address of the remote interface. |
Remote EFM Enable Flag | Whether EFM OAM is enabled on the remote interface:
|
Remote Mode | EFM OAM working mode of the remote interface:
|
Remote MaxSize | Maximum size of the OAM PDU on the remote interface. |
Remote Loopback IgnoreRequest | Whether the remote interface ignores loopback requests sent by the local interface:
|
Remote Parser | Remote parser:
|
Remote Multiplexer | Remote multiplexer:
|
Interface | Name of the interface with EFM OAM enabled. |
Mode | EFM OAM working mode of the interface:
If the interfaces connecting CE and PE both work in passive EFM mode, run the efm mode active command on one of the interfaces to change the working mode from passive to active. |
ErrCodeNotification | Whether bit error detection is enabled on the interface:
|
ErrCodePeriod | Period during which bit errors are detected on the interface. |
ErrCodeThreshold | Threshold for the number of bit errors detected on the interface. |
ErrFrameNotification | Whether errored frame detection is enabled on the interface:
|
ErrFramePeriod | Period during which errored frames are detected on the interface. |
ErrFrameThreshold | Threshold for the number of errored frames detected on the interface. |
ErrFrameSecondNotification | Whether errored frame second detection is enabled on the interface:
|
ErrFrameSecondPeriod | Period during which errored frame seconds are detected on the interface. |
ErrFrameSecondThreshold | Threshold for the number of errored frame seconds detected on the interface. |
TriggerIfDown | Whether the interface is blocked if a fault is detected on the link between the interface and its remote interface:
|
TriggerMacRenew | Whether the MAC is cleared if a fault is detected on the link between the interface and its remote interface:
|
ErrFramePeriodNotification | Whether the interface is enabled to notify its peer device of errored frames that EFM periodically detects:
|
ErrFramePeriodPeriod | Interval at which EFM detects errored frames among a specified number of frames that the interface receives. |
ErrFramePeriodThreshold | Threshold for EFM errored frame period detection on the interface. |
Multiplexer | local Multiplexer. |
Parser | local Parser. |
