4.3.3 Configuring the Working Mode of EFM OAM on an Interface
EFM OAM working mode is an attribute of an EFM OAM-enabled interface, and consists of
the active mode and the passive mode.
Context
NOTE
The working mode of EFM OAM on the interface can be configured only after EFM OAM is enabled
globally and before EFM OAM is enabled on the interface. The working mode of EFM OAM on the
interface cannot be modified after EFM OAM is configured on the interface.
Do as follows on the devices at both ends of the link:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view of an interface at one end of the link is displayed.
Step 3 Run:
efm mode { active | passive }
The working mode of EFM OAM on the interface is configured.
By default, EFM OAM on an interface works in active mode.
At least one interface at both ends of the link must be configured to work in active mode. The
interface in active mode initiates OAM discovery after EFM OAM is enabled on the interface.
Instead of initiating OAM discovery, the interface in passive mode waits for an OAMPDU sent
from the interface in active mode. If both interfaces are configured to work in active mode, you
can implement link detection. If both interfaces are configured to work in passive mode, OAM
discovery fails.
