Configuring IEEE 802.3ah OAM Link-Fault Management

 

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 CLI Explorer.
