Usage Guidelines

Usage Scenario

If CFM cannot work properly, run the display cfm error-info command to check received CCMs with unknown MEP IDs. The information helps diagnose a fault.

If no parameter is configured in the display cfm error-info command, the device displays CCMs with unexpected MEP IDs received by all MEPs.
If an MD name, an MA name, or a MEP ID is specified, the device displays CCMs with unexpected MEP IDs received by a specified MEP.

Prerequisites

CFM has been enabled globally using the cfm enable (system view) command.

Precautions

IEEE 802.1ag has two versions: IEEE 802.1ag Draft 7 and IEEE Standard 802.1ag-2007. This command can be used only on the device running IEEE Standard 802.1ag-2007.

Example
