[VOL-2875] Documentation update General language (spelling, flow) fixes Remove redundant documentation Change protos Makefile to generate directory using dependencies (Cherry pick of https://gerrit.opencord.org/c/18482/ ) Change-Id: I24fb2c9259c1a29b7499a35fd13e50836333c58e
The OpenOLT agent runs on white box Optical Line Terminals (OLTs) and provides a gRPC-based management and control interface to OLTs.
The OpenOLT agent is used by VOLTHA through the OpenOLT adapter.
OpenOLT agent uses Broadcom's BAL (Broadband Access Layer) software for interfacing with the Maple/Qumran chipsets in OLTs such as the Edgecore/Accton ASXvOLT16.

A list of tested devices and optics can be found in the CORD hardware requirements guide, in the R-CORD access equipment and optics section.
Accton/Edgecore makes available pre-built debian packages of OpenOLT agent to their customers. Get access credentials for edgecore.quickconnect.to and then login and navigate to File_Station -> EdgecoreNAS
, and then the folder /ASXvOLT16/OpenOLT_Agent/From_ONF_Distribution/
and pick the right version of .deb
package required for your testing.
voltha-2.3/openolt-2.3.0.deb
is the latest version of package with support for BAL3.2.3.2 .
The pre-built debian packages have been tested on Open Networking Linux (ONL) version 4.14. The ONL Installer required for voltha-2.3/openolt-2.3.0.deb is also available at in the same path, i.e., voltha-2.3/.
Copy the debian package to the OLT. For example:
scp openolt.deb root@10.6.0.201:~/.
Install the openolt.deb package using dpkg:
dpkg -i openolt.deb
The ONL version required for BAL3.2.3.2 is ONL 4.14.109-OpenNetworkLinux
. This will be built as part of build procedure described Build OpenOLT
section.
Rebooting the OLT (after the installation) will start dev_mgmt_daemon
and openolt
as system services:
reboot
The services can also be stopped/started manually:
service dev_mgmt_daemon stop
service openolt stop
service dev_mgmt_daemon start
service openolt start
Check the status of the services:
service dev_mgmt_daemon status
service openolt status
Running the dev_mgmt_daemon
and/or openolt
services in the foreground is useful for development and debugging. Make sure to first stop the services if they are running in background.
service dev_mgmt_daemon stop
service openolt stop
Open a terminal and run the Broadcom BAL software (dev_mgmt_daemon
):
cd /broadcom ./dev_mgmt_daemon -d -pcie
The dev_mgmt_daemon
executable presents the CLI for Broadcom's BAL when run in the foreground which is useful for debugging.
While the first executable still runs (even in background), open another terminal and run openolt
:
cd /broadcom ./openolt
NOTE: the two executables will remain open in the terminals, unless they are put in background.
At the VOLTHA CLI, preprovision and enable the OLT:
(voltha) preprovision_olt -t openolt -H YOUR_OLT_MGMT_IP:9191 (voltha) enable
Currently, OpenOLT supports Broadcom's BAL API, version 3.2.3.2.
The following proprietary source code is required to build the OpenOLT agent.
SW-BCM686OLT_<BAL_VER>.tgz
- Broadcom BAL source and Maple SDKsdk-all-<SDK_VER>.tar.gz
- Broadcom Qumran SDKACCTON_BAL_<BAL_VER>-<ACCTON_VER>.patch
- Accton/Edgecore's patchThe versions currently supported by the OpenOLT agent are:
SW-BCM686OLT_3_2_3_2.tgz
sdk-all-6.5.13.tar.gz
ACCTON_BAL_3.2.3.2-V201912230101.patch
NOTE: the repository does not contain the above three source packages. These are needed to build the OpenOLT agent executable. Contact Dave Baron at Broadcom to access the source packages.
Hardware :
CPU: Dual-core (4 Threads) up.
Memory: 6GB
Storage: 40GB of free space.
Software :
OpenOLT agent builds on Ubuntu 16.04 LTS.
At least 4G of ram and 4G of swap - compilation is memory intensive
Essential tools for building packages
sudo apt-get install build-essential ccache
Install cmake version 3.5.0 or above. Download cmake-3.5.0.tar.gz and untar it, then in the cmake-3.5.0 directory install by running:
./bootstrap && make && make install
Clone the openolt
repository either from OpenCORD Gerrit:
git clone https://gerrit.opencord.org/openolt
Copy the Broadcom source and patch files to the openolt/agent/download directory:
cd <dir containing Broadcom source and patch files> cp ACCTON_BAL_3.2.3.2-V201912230101.patch SW-BCM686OLT_3_2_3_2.tgz sdk-all-6.5.13.tar.gz <cloned openolt repo path>/agent/download
Run the configure script to generate the appropriate Makefile scaffolding for the desired target:
cd openolt/agent ./configure
Run make prereq
to install the package dependencies. This is usually a one-time thing, unless there is a change in the dependencies.
make OPENOLTDEVICE=asfvolt16 prereq
Run make. This can take a while to complete the first time, since it builds ONL and the Broadcom SDKs. Following runs will be much faster, as they only build the OpenOLT agent source.
make OPENOLTDEVICE=asfvolt16
Note that the required ONL version 4.14
is built as part of the above build procedure and is available at path build/onl/OpenNetworkLinux/RELEASE/jessie/amd64/ONL-onl-4.14_ONL-OS8_2019-09-24.0446b4af32e_AMD64_INSTALLED_INSTALLER
. This ONL Installer should be used to flash the OS on the OLT.
If you need to use a specific version of voltha-protos, then specify the git tag/branch corresponding to that specific version:
make OPENOLTDEVICE=asfvolt16 OPENOLT_PROTO_VER=master
By default, the OPENOLT_PROTO_VER
defaults to git tag v3.1.0 of the voltha-protos repo.
If the build process succeeds, libraries and executables will be created in the openolt/agent/build directory.
Optionally, build the debian package that will be installed on the OLT.
make OPENOLTDEVICE=asfvolt16 deb
If the build process succeeds, a .deb
package will be created as well in the openolt/agent/build
directory.
NOTE: To compile for ASGvOLT 64 port GPON OLT, set OPENOLTDEVICE
to asgvolt64
during build procedure like below.
make OPENOLTDEVICE=asgvolt64
To cleanup the repository and start the build procedure again, run:
# cleans up the agent objects, protos compiled artificats and openolt deb packages make OPENOLTDEVICE=asfvolt16 clean # cleans up the agent objects, protos compiled artificats, openolt deb packages and bal sources make OPENOLTDEVICE=asfvolt16 distclean
The information here may be specific to specific OLT and ONU hardware such as Edgecore ASFVOLT16 OLT and Broadcom based ONUs.
Auto-negotiation on the NNI (Network to Network Interface) uplink ports is not tested.
By default, the OpenOLT agent sets the speed of the NNI interfaces to 100G. To downgrade the network interface speed to 40G, add the following lines at the end of the /broadcom/qax.soc
configuration file.
port ce128 sp=40000
A restart of the dev_mgmt_daemon
and openolt
services is required after making this change.
The firmware on the ONU is likely not setup to forward 802.1x EAPOL traffic on the Linux bridge. Drop down to the shell in the Broadcom ONU's console and configure the Linux bridge to forward 802.1x.
> sh # echo 8 > /sys/class/net/bronu513/bridge/group_fwd_mask
Version 1.7 of VOLTHA has a known issue where the ONU is only able to pass EAPOL packets from a specific LAN port (e.g. LAN port 1 on ALPHA ONUs)
LAN port packet counters:
bs /b/e port/index=lan{0,1,2,3,4,5,6}
WAN port packet counters:
bs /b/e port/index=wan0
