SONiC on Cisco 8000 Series Routers, Release 202012

Cisco 8000 series routers support disaggregating the hardware and software to provide a more robust, open ecosystem for service provider networks.

With the introduction of Open Compute Project (OCP), vendors collaborate on designs and specifications to enable a more efficient, scalable, and versatile consumption of hardware and software. This initiative broadens the spectrum for cloud and service provider transformations, hardware innovations, software evolutions, flexibility, lower costs, and better control of the network infrastructure.

As part of the disaggregation journey, Cisco introduces support for installing Software for Open Networking in the Cloud (SONiC) on fixed form factors on the Cisco 8000 series routers.

Description

8102-64H-O

Cisco 8100 2 RU Chassis with 64x100G QSFP28 with Open Software and without HBM on Q200 Silicon

SONiC is an open source network operating system based on Linux that runs on switches from multiple vendors and ASICs. SONiC offers a full-suite of network functionality, like BGP and RDMA, that has been production-hardened in the data centers of some of the largest cloud-service providers. Cisco is part of this ecosystem harnessing the innovation in Cisco Silicon One to provide seamless infrastructure experience in data center deployments. Cisco Silicon One devices can assign ports to be generic Ethernet or a fully scheduled fabric. The Cisco Silicon One architecture enables optimized fixed form factor systems. Cisco leverages the SONiC capabilities from the community for a deployment-hardened network stack on the Cisco 8000 series routers.

SONiC uses Switch Abstraction Interface (SAI) API version 1.7.1 for release 202012. The SAI API defines the API to provide a mechanism to control forwarding elements, such as a switching ASIC, an NPU or a software switch in a uniform manner. For more information about SAI APIs, refer the Github repository.

For more information about the benefits of integrated innovation, see Cisco 8000 series routers.

SONiC on DevNet Sandbox

We want you to interact with SONiC on the Cisco 8000 router. Introducing SONiC on DevNet Sandbox!

You see in action, a 3-stage Clos topology bring-up and deploy a reliable network that is optimised for latency.

We included a narration to summarise the main ideas in each stage. As you hit the Play button, configurations are applied on the Cisco 8000 router running as an Emulator in the DevNet Sandbox. You see real-time responses from the Emulator. What’s more, you can add your own configurations and interact with the setup.


Note

Some features like the Priority Flow Control (PFC), Bidirectional Forwarding Detection (BFD) are not supported on the Emulator.
