Frequently Asked Questions

What is OpenSwitch OPX Base?

Answer

OpenSwitch OPX Base is an innovative operating system for network systems. It uses an unmodified Linux kernel and standard distribution to take advantage of rich ecosystem, and also provide flexibility in customizing your system according to your network needs.

How do I build an ONIE installer image?

Answer

The build process is fully automated (see OpenSwitch ONIE installer and opx-build for complete information).

 Which hardware platforms are you running OPX Base on?

Answer

The current release of OPX Base supports Dell EMC S3048-ON, S4048-ON/S4048T, S4128F-ON/S4128T-ON, S4148F-ON/S4148FE-ON, S4148T-ON, S4248FB-ON/S4248FBL-ON, S5148F-ON, S6010-ON, Z9100-ON, and Edgecore 7512-32X devices only. Future implementations will support various devices, platforms, and ASIC vendors.

Which ASIC vendors are you working with for future development?

Answer

We’re currently working with Broadcom, Barefoot Networks, Cavium, and Innovium just to name a few.

Do you recommend using the Linux standard drivers and interfaces in the SDI layer or are they vendor-provided?

Answer

We do recommend using the vendor drivers that currently exist in Linux today, but we don’t recommend system vendors or ODM platforms to provide kernel-level modules or kernel modifications.

How can I contribute to OPX Base?

Answer

OPX Base welcomes collaboration with the community in many different capacities. See Contribute to OPX BaseContribute to OpenSwitch, and Report bugs for complete information.

 Is OPX Base a Linux distribution?

Answer

OPX Base is Linux-based but not a distribution by itself. OPX Base runs on Debian Jessie and has also been ported to Ubuntu (see opx-build for complete information).

How do I build an OPX Base image?

Answer

See OpenSwitch build system for complete information on how to produce an OpenSwitch OPX Base image.

Why are certain SAI implementations only distributed in binary form?

Answer

SAI defines the common API supported by multiple ASIC vendors. The SAI implementation depends on each individual vendor’s SDK, which may not be open-sourced itself. Depending on the vendor’s license model, OPX Base may or may not be allowed to open source the SAI implementation.

What is your testing strategy for multiple ASIC vendors to check in code?

Answer

We have an initial test framework which is based on Ansible test suites. ASIC vendors have the ability to use OpenSwitch itself, run it on their platforms, and run the test suite that we’re building. We’re currently working on testing and qualification labs for future releases.

How can I port OPX Base to a new device?

Answer

See the OPX Base porting guide for complete information.

Does OPX Base support ToR as well as modular switches?

Answer

OPX Base supports both ToR and modular switches using the CPS layer. The CPS layer allows you to configure a group of switches together, and then talk to them all through the CPS layer (as if they were local). Although the ON-Series platform supports it, OPX Base does not currently support fabric in this release.
