Usage Guidelines

Usage Scenario

For continuity check on an interface where a MEP is configured, if a service is bound to the interface, to allow the peer device to clearly detect network faults, run the ccm tlv port-status command to enable CCMs to be sent to carry the Port Status TLV field. The interface's blocking status is encapsulated in a CCM's Port Status TLV field and sent to the peer device.

Example

# Enable CCMs to be sent to carry the Port Status TLV field.
