Configuring a Connectivity Fault Management Action Profile

You can configure an action profile and specify the action to be taken when any of the configured events occur. Alternatively, you can configure an action profile and specify default actions when connectivity to a remote maintenance association endpoint (MEP) fails.

To configure the action profile name, include the action-profile statement at the [edit protocols oam ethernet connectivity-fault-management] hierarchy level.

Configuring the Action of a CFM Action Profile

You can configure the action to be taken when any of the configured events occur.

To configure the action profile’s action, include the action statement at the [edit protocols oam ethernet connectivity-fault-management action-profile profile-name] hierarchy level.

[edit protocols oam]ethernet {connectivity-fault-management {action-profile bring-down {event {interface-status-tlv down;}action {interface-down;}}}}

Configuring the Default Actions of a CFM Action Profile

You can configure the default actions to be taken when connectivity to a remote MEP fails.

To enable the interface-down as the default action for an action profile, include the interface-down statement at the [edit protocols oam ethernet connectivity-fault-management action-profile profile-name default-actions] hierarchy level.

[edit]protocols {oam {ethernet {connectivity-fault-management {action-profile bring-down {default-actions {interface-down;}}maintenance-domain md1 {level 0;maintenance-association ma1 {continuity-check {interval 100 ms;}mep 4001 {interface ge-4/1/0;direction down;remote-mep 1 {action-profile bring-down;}}}}}}}}

Note: Associating an action-profile with the action of interface-down on an up MEP CFM session running over a circuit cross-connect (CCC) interface (l2circuit/l2vpn) is not advisable and can result in a deadlock situation.

Configuring a CFM Action Profile Event

You can configure one or more events under the action profile, the occurrence of which triggers the corresponding action to be taken.

To configure the interface-status-tlv lower-layer-down event, include the interface-status-tlv lower-layer-down statement at the [edit protocols oam ethernet connectivity-fault-management action-profile profile-name event] hierarchy level.

To configure the interface-status-tlv down event, include the interface-status-tlv down statement at the [edit protocols oam ethernet connectivity-fault-management action-profile profile-name event] hierarchy level.

To configure the port-status-tlv blocked event, include the port-status-tlv blocked statement at the [edit protocols oam ethernet connectivity-fault-management action-profile profile-name event] hierarchy level.

To configure the adjacency-loss event, include the adjacency-loss statement at the [edit protocols oam ethernet connectivity-fault-management action-profile profile-name event] hierarchy level.

To configure an RDI event to bring an interface down on reception of an RDI bit from a MEP, include the rdi statement at the (edit protocols oam ethernet connectivity-fault-management action-profile profile-name event] hierarchy level.

[edit protocols oam]ethernet {connectivity-fault-management {action-profile bring-down {event {adjacency-loss;interface-status-tlv (down | lower-layer-down);port-status-tlv blocked;rdi;}action {interface-down;}clear-action {interface-down peer-interface ;}}}}

Note: You cannot configure multiple actions at this time. Only one action can be configured. This limitation affects both the action and clear-action statements.
