Troubleshooting

This section offers advices in a case OpenDaylight PCEP plugin is not working as expected.

PCEP is not working…

• First of all, ensure that all required features are installed, local PCE and remote PCC configuration is correct.

  To list all installed features in OpenDaylight use the following command at the Karaf console:

  feature:list -i
  

• Check OpenDaylight Karaf logs:

  From Karaf console:

  log:tail
  

  or open log file: data/log/karaf.log

  Possibly, a reason/hint for a cause of the problem can be found there.

• Try to minimize effect of other OpenDaylight features, when searching for a reason of the problem.

• Try to set DEBUG severity level for PCEP logger via Karaf console commands, in order to collect more information:

  log:set DEBUG org.opendaylight.protocol.pcep
  

  log:set DEBUG org.opendaylight.bgpcep.pcep
  

and for Path Computation Algorithm

log:set DEBUG org.opendaylight.algo

Bug reporting
