This document describes about hardware setup to use OF-DPA.

Pre-requirements

  • The installation is required in advance. Please refer install.md before proceeding.
  • The setup of Beluganos is required in advance. Please refer setup.md before proceeding.
  • The installation of OpenNetworkLinux for your white-box switches is required in advance. Please refer setup-hardware.md before proceeding.

Install OF-DPA

OF-DPA is a ASIC driver. After installing OpenNetworkLinux, OF-DPA settings are required to use Beluganos.

Get binary (.deb)

Please get the binary of OF-DPA. The required version of OF-DPA is 2.0.4. The following website is published OF-DPA binary.

In this section, using ofdpa-2.0-ga_2.0.4.0+accton2.4-1_amd64.deb which got from Edge-core's repository is assumed.

Install

The following steps are required in case of the first time to use OF-DPA.

(Step 1) Transfer OF-DPA binary

Transfer the binary to OpenNetworkLinux. For example, SCP or SFTP are assumed. Assumed file name is here:

  • ofdpa-2.0-ga_2.0.4.0+accton2.4-1_amd64.deb

(Step 2) Install OF-DPA

ONL> dpkg -i --force-overwrite ofdpa-2.0-ga_2.0.4.0+accton2.4-1_amd64.deb

Configure OF-DPA

(Step 1) Link up required ports

In default settings, almost all physical port is set to down. For example, you want to use port 30, following step is required:

ONL> echo 0 > /sys/bus/i2c/devices/30-0050/sfp_tx_disable

If you prefer to up all ports, following example of scripts is recommended.

#! /bin/bash

for ((i = 2; i <= 54; i = i + 1)); do
  echo 0 > /sys/bus/i2c/devices/$i-0050/sfp_tx_disable
done

(Step 2) Start OF-DPA and OpenFlow agent

To start, following commands are required:

ONL> service ofdpa start

~~~(Please wait over 15 sec.)~~~

ONL> brcm-indigo-ofdpa-ofagent --controller=<BeluganosVM-IP> --dpid=<Agent-dpid>
  • <BeluganosVM-IP>: Specify Beluganos's IP address. Please note that you already specify this IP address in create.ini at install.md.
  • <Agent-dpid>: Specify OpenFlow DPID. Please note that you already specify this ID in fibc.yml at setup.md. The default settings is 14.

If you can confirm that OF-DPA is launched properly, please stop it at once by Ctrl+C and service ofdpa stop. After configure, please re-run it.

Next Steps

The prepare to try Beluganos is almost finished! In the next step, you should configure router settings like IP address, VLAN, and protocol settings. Please refer configure.md.
