Troubleshooting Two-Way Delay Measurement Configuration
Table 4 lists the debug commands to troubleshoot issues pertaining to the two-way delay measurement
configuration. The Cisco IOS Master Command List at
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.
Table 4 debug Commands for Two-Way Delay Measurement Configuration
debug Command Purpose
debug epmpal all Enables debugging of all Ethernet performance
monitoring (PM) events.
debug epmpal api Enables debugging of Ethernet PM API events.
