Flexswitch Support for Ingrasys S9100

Overview

FlexSwitch by SnapRoute is a disaggregated micro-services based L2/L3 network stack, enabling organizations to achieve maximum agility, reliability, and security.

It has open source version on two sites:

• OpenSnaproute (Deprecated)
• OpxFlexswitch

Network Stack Support

Our patches for FlexSwitch network stack uses open source code released at OpenSnaproute to be the stack codebase, and leverage code from OpxFlexswitch to fix issues.

Note: The code on OpenSnaproute has been removed. We push the original code to the site to be our codebase.

Asicd Support

Snaproute's asic daemon serves as a hardware abstraction layer (HAL). Our implementation is based on open source code at asicdopen. We complete the SAI plugin implementaion using SAI API 0.9.4. We have verified it works on our white box Ingrasys S9100 and S8900 using Broadcom Tomahawk chip.

Features

• BFP
• BGP
• DHCP relay
• ECMP
• LAG
• LLDP
• Loopback
• OSPF
• STP
• VRRP

Build Guide

From this site, you have two ways to test FlexSwitch. One is to build the docker version package (Using Linux kernel driver), and the other is to build Ingrasys S9100 version package (Using asicd with SAI plugin). You can use the following process to build packages. The deb files could be found under the folder reltools.

Developing Environment Setup

Prerequisites

Prepare Ubuntu 14.04.

Setup Environment

1. Install git-lfs

   $ curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | sudo bash
   $ sudo apt-get install git-lfs
   $ git lfs install
   

   Check git-lfs if you are failed to install git-lfs.

2. Install go and fabric

   $ sudo apt-get install -y build-essential fabric git wget
   $ sudo apt-get install -y libnl-3-200 libnl-genl-3-200
   $ wget https://storage.googleapis.com/golang/go1.5.3.linux-amd64.tar.gz
   $ sudo tar -C /usr/local -xzf go1.5.3.linux-amd64.tar.gz
   

3. Download source code

   Change to directory you want to use for downloading source code. You could choose any folder in Home directory. By default, your code will be put into ~/git.

   $ git clone https://github.com/FlexSNR/reltools
   $ cd reltools
   $ fab setupDevEnv
   

   There should be some interactive questions. Type FlexSNR for username, and press enter for others to use default value.

   Host directory: [git]
   Git username: FlexSNR
   Git Protocol (https/ssh): [https]
   SnapRoute Employee (y/n): [n]

   Note: If you choose another folder to store source code, replace git by your folder name.

4. Configure environment variable

   $ export PATH=$PATH:/usr/local/go/bin
   $ export SR_CODE_BASE=~/git
   $ export GOPATH=~/git/snaproute:~/git/external:~/git/generated
   

Build docker version

$ python makePkg.py

Build Ingrasys S9100 version

Change directory to ~/git.

$ git clone https://github.com/FlexSNR/FlexSNR-Patch
$ cd FlexSNR-Patch
$ ./patch_util
$ cd ../reltools
$ python makePkg.py

Note: To build successfully, you need to contact us for asic-related files
