The OF-DPA package is a Debian package that includes the OF Agent.
Download from here:
Please note: Only this version of OF-DPA will work for the fabric in ONOS 1.8 used in CORD 2nd release (Mysterious Decision) and 3rd release (Dangerous Addition).
Copy the package to /mnt/onl/data
Install the OF-DPA package. (Note that this is required every time after rebooting. I will show a trick later so it can be done automatically.)
Run Indigo OpenFlow Agent to connect the switch to controller(s).
In OFDPA 3.0 EA0, OF agent doesn't sync information with OFDPA service after restart.
Please make sure you restart OFDPA service to empty the hardware flow/group table every time you restart the Indigo OF agent.
