Deadlock avoidance using modified ethernet connectivity fault management signaling

A first maintenance endpoint (MEP) device, comprising:

• a memory;
• and
• one or more processors to:
• receive, from a second MEP device, a first continuity check message (CCM) based on an interface status of the second MEP device,
• the first CCM including a MEP identifier of the second MEP device;
• perform an action based on an action profile and based on receiving the first CCM;
• and
• provide, to the second MEP device, a second CCM that includes the MEP identifier of the second MEP device and information indicating that the action was performed,
• the second CCM to cause the second MEP device to execute a rule to avoid a deadlock situation.

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors by a first maintenance endpoint (MEP) device, cause the one or more processors to:
• receive, from a second MEP device, a first continuity check message (CCM) based on an interface status of the second MEP device,
• the first CCM including a MEP identifier of the second MEP device;
• perform an action based on an action profile and receiving the first CCM;
• and
• provide, to the second MEP device, a second CCM that includes the MEP identifier of the second MEP device and information indicating that the action was performed,
• the second CCM to cause the second MEP device to execute a rule to avoid a deadlock situation.

A method comprising:

• receiving, by a first maintenance endpoint (MEP) device and from a second MEP device, a first continuity check message (CCM) based on an interface status of the second MEP device
• the first CCM including a MEP identifier of the second MEP device;
• performing, by the first MEP device, an action based on an action profile and receiving the first CCM;
• and
• providing, by the first MEP device and to the second MEP device, a second CCM that includes the MEP identifier of the second MEP device and information indicating that the action was performed,
• the second CCM to cause the second MEP device to execute a rule to avoid a deadlock situation.
