2
(Optional) Faulty-state hold timer
4.6.2 Associating EFM OAM with an Interface
By associating EFM OAM with a physical interface, you can use the OAM management module
to notify the bound interface management module of fault information after EFM OAM detects
a fault.
Context
After EFM OAM is enabled on an interface, the status of this interface changes when the interface
receives an OAM PDU control request packet with the Link Fault Status flag.
There are two ways to associate EFM OAM with an interface:
l
Associating an error event with an interface and setting the interface to the blocking state
when the error event occurs.
l
Associating an error event with an interface and setting the interface to the disabled state
when the error event occurs.
l
Associating a threshold crossing event with an interface.
Do as follows on the devices at one end or both ends of the link:
Procedure
l
Associate an error event with an interface and set the interface to the blocking state when
the error event occurs.
