Troubleshooting

Use the pppoeControlPacket log to diagnose problems on your PPPoE interfaces.

log severity debug pppoeControlPacket

• Use to configure a packet trace log for a PPPoE interface. You must specify a PPPoE major interface.
• Specify one of the following interface types and a corresponding interface specifier. For more information, see Interface Types and Specifiers.
  • fastEthernet
  • gigabitEthernet
  • atm
  • tenGigabitEthernet
• The packet trace log for a PPPoE interface displays only the first 256 bytes of packet data. Data in excess of 256 bytes does not appear in the packet trace log.
• You also configure logging to direct the output to a specific destination. For information, see Overview of System Logging.
