The following example shows how to enable the OAM link-fault management feature
on an interface and configure a link monitoring operation for frame seconds events on
the interface.
Specify the Gigabit Ethernet interface on which OAM link-fault management needs
1.
to be enabled, and configure the link discovery mode as active. When OAM functionality
is enabled on the interface, the discovery mode of the local OAM entity is set to active
by default. An OAM entity in active mode initiates the discovery process by sending
an Information OAM PDU to the multicast address of the slow protocol
(0180.c200.0002) at a configured rate.
host1(config)#interface gigabitEthernet 4/1
host1(config-if)#ethernet oam lfm mode active
Configure the Ethernet OAM link-fault management functionality to detect link-fault
2.
and dying-gasp conditions that occurred in the receive path of the link and influence
the state of the link based on an Event Notification PDU received from the remote
peer. Link Fault means a loss of signal, Dying Gasp means an unrecoverable condition
such as a power failure.
host1(config-if)#ethernet oam lfm remote-failure dying-gasp action disable-interface
host1(config-if)#ethernet oam lfm remote-failure link-fault action disable-interface
Configure the local interface to be disabled when the high threshold for an error
3.
condition is exceeded. The OAM functionality unconditionally attempts to influence
the operational state of the interface to down.
host1(config-if)#ethernet oam lfm high-threshold action disable-interface
Configure link monitoring operations for frame error events on the interface. Specify
4.
the high threshold in number of frames for frame error events as 200, which when
exceeded causes an action to be triggered. Specify a low threshold for frame error
events, which when exceeded causes an Errored Frame Seconds Summary Event TLV
to be sent to the peer, as 20 frames. Also, set the window during which frame error
events are counted as 300 hundred millisecond units or 30 seconds.
host1(config-if)#ethernet oam lfm link-monitor frame-seconds threshold high 200
host1(config-if)#ethernet oam lfm link-monitor frame-seconds threshold low 20
host1(config-if)#ethernet oam lfm link-monitor frame-seconds window 300
