To verify your CFM configuration, you can display the current CFM configuration using the show cfm command.
The information this command displays includes the total ports configured for CFM, the domain names and MD levels, the MAs and associated service instances, and the UP and DOWN MEPs.
To display the CCM database for each MEP, use the show cfm detail command.
Counters are added for missed-hellos, which mainly help to constantly monitor the health of CFM session path and hence tweaking the configured interval times to get the best reliability with the shortest fail over times for radio and wireless networks that rely on CFM to detect any failures. These counters can be displayed using show cfm session counters missed-hellos command. The counters can be cleared using "clear counters cfm session missed-hellos" command.
