DUT(config)#interface eth-0-9 Specify the interface (eth-0-9)to be
configured and enter the Interface
mode
DUT(config-if)# ethernet oam enable Enable Ethernet OAM in eth-0-9
DUT(config-if)# ethernet oam mode active Configure Ethernet OAM mode as
active.
(The default mode is passive.)
DUT(config-if)# ethernet oam timeout 10 Configure the link-timer as 10. Upon
expiry of the link timer, the discovery
process will restart.
DUT(config-if)# ethernet oam max-rate 1 Specify the maximum number of
OAMPDUS to be sent per .The range
is <1-10>
DUT(config-if)# end Exit the Interface mode.
Validation
The EFM Discovery Machine State should be “send any" in both machines. This is the expected normal
operating state for OAM on fully-operational links.
The various states of OAM discovery state machine are defined below.
ACTIVE_SEND_LOCAL
A DTE configured in Active mode sends Information OAMPDUs that only contain the Local Information
TLV. This state is called ACTIVE_SEND_LOCAL. While in this state, the local DTE waits for Information
OAMPDUs received from the
remote DTE.
PASSIVE_WAIT
DTE configured in Passive mode waits until receiving Information OAMPDUs with Local Information TLVs
before sending any Information OAMPDUs with Local Information TLVs. This state is called
PASSIVE_WAIT. By waiting until first receiving an Information OAMPDU with the Local Information TLV, a
Passive DTE cannot complete the OAM Discovery process when connected to another Passive DTE.
SEND_LOCAL_REMOTE
Once the local DTE has received an Information OAMPDU with the Local Information TLV from the remote
DTE, the local DTE begins sending Information OAMPDUs that contain both the Local and Remote
Information TLVs. This state is called SEND_LOCAL_REMOTE.
SEND_LOCAL_REMOTE_OK
If the local OAM client deems the settings on both the local and remote DTEs are acceptable, it enters the
SEND_LOCAL_REMOTE_OK state.
SEND_ANY
Once an OAMPDU has been received indicating the remote device is satisfied with the respective settings,
the local device enters the SEND_ANY state. This is the expected normal operating state for OAM on fully
operational links.
FAULT
If OAM is reset, disabled, or the link timer expires, the Discovery process returns to the FAULT state.
