Chapter Configuring Ethernet CFM and Y.1731 Performance Monitoring on Layer 3 Interfaces
CFM Support on Routed Port and Port MEP
http://www.cisco.com/en/US/docs/ios/mcl/allreleasemcl/all_book.html provides more information
about these commands.
Caution Because debugging output is assigned high priority in the CPU process, it can diminish the performance
of the router or even render it unusable. For this reason, use debug commands only to troubleshoot
specific problems or during troubleshooting sessions with Cisco technical support staff.
Note Before you run any of the debug commands listed in the following table, ensure that you run the logging
buffered debugging command, and then turn off console debug logging using the no logging console
command.
