You can configure threshold values for fault events that trigger the sending of link event
TLVs when the values exceed the threshold. To set threshold values for fault events on
an interface, include the event-thresholds statement at the [edit protocols oam ethernet
link-fault-management interface] hierarchy level.
You can also configure OAM threshold values within an action profile and apply the action
profile to multiple interfaces. To create an action profile, include the action-profile
statement at the [edit protocols oam ethernet link-fault-management] hierarchy level.
You can configure Ethernet OAM either on an aggregate interface or on each of its member
links. However, we recommend that you configure Ethernet OAM on the aggregate
interface, and this will internally enable Ethernet OAM on the member links.
To view OAM statistics, use the show oam ethernet link-fault-management operational
mode command. To clear OAM statistics, use the clear oam ethernet
link-fault-management statistics operational mode command. To clear link-fault
management state information and restart the link discovery process on Ethernet
interfaces, use the clear oam ethernet link-fault-management state operational mode
command. For more information about these commands, see the Junos OS Operational
Mode Commands.
