How to enable debugging mode on OF-DPA

Introduction to Broadcom OF-DPA

Broadcom’s OpenFlow Data Plane Abstraction (OF-DPA) is an application software component that implements an adaptation layer between OpenFlow and the Broadcom Silicon SDK. OF-DPA enables scalable implementation of OpenFlow 1.3.4 on Broadcom switch devices.

  • -d, --ofdpadebuglvl=OFDPADEBUGLVL
    • The verbosity of OF-DPA debug messages
    • Valid OF-DPA debug levels are 0 - 4. (By default is 0)
  • -a, --agentdebuglvl=AGENTDEBUGLVL
    • The verbosity of OF Agent debug messages
    • Valid OF Agent debug levels are 0 - 2. (By default is 0)
  • -i, --dpid=DATAPATHID
    • Specify Datapath ID (By default is 0x000000000000DA7A)
  • -l, --listen=IP:PORT
    • Listen port
  • -t, --controller=IP:PORT
  • -c, --ofdpadebugcomp=OFDPACOMPONENT
    • The OF-DPA component for which debug messages are enabled
    • List of OFDPACOMPONENT
      • 1 = API
      • 2 = Mapping
      • 3 = RPC
      • 4 = OFDB
      • 5 = Datapath
      • 6 = G8131
      • 7 = Y1731
