SEBA Testing

This page is about work in progress regarding SEBA validation and testing, more information should be added in the near future.

SEBA on ARM - porting and upstreaming work on this wiki describes the work done for porting and verifying SEBA on ARM servers in particular.

On the the more general subject of testing SEBA as a whole, there were some emails exchanged on the Akraino technical-discuss mailing list, where some valuable feedback was received from Zack Williams of Open Network Foundation:

More input was received from @Aaron Byrdhere:

SEBA-in-a-Box and PONsim

For validation purposes, the SIAB guide shows how to easily deploy SEBA on a single server and install PONsim for emulating real OLT/ONU hardware. See the SEBA-in-aBox guide

Installing PONsim on IEC

The installation instruction on the SIAB guide asume you are installing SEBA either using automation-tools, or by deploying the components individually using the charts on https://gerrit.opencord.org/helm-charts

It should be possible however to use PONsim on the Akraino IEC platform, after installing SEBA as described in SEBA Installation Guide. These have not been verified on ARM servers yet and some errors occurs when pods get scheduled on different servers, since IEC platform defines 3 servers for the Kubernetes cluster.

Here are some crude, general instructions on how to install SEBA and PONsim on the IEC platform. The instructions have been tailored for working with the IEC platform, as per the instructions on IEC Blueprints Installation Overview, using the OPNFV Fuel installer.

Some networking aspects have been changed to match the network addresses used by the installer, but you can always compare with the SIAB installation guide to match your environment.

# Again on the RG POD, you need to run dhclient to obtain a valid IP address from the 172.18.0.0/24 subnet

Test cases to validate Host OS Environment for SEBA installation  NOT COMPLETE - Needs to be updated  - Feel free to add validation (where needed)

NOTE: SEBA specific functional testing & validation is documented in SEBA upstream project - https://guide.opencord.org/cord-6.1/cord-tester/

1. OS Version Test:

2. Repo Connectivity Test: (Offline install)

3. NIC Interface Test:
