The Switch Abstraction Interface(SAI) defines the API to provide a vendor-independent way of controlling forwarding elements, such as a switching ASIC, an NPU or a software switch in a uniform manner.
This repository contains SAI implementation for Centec switching ASICs. Customers can configure Centec switching ASICs by SAI APIs in SONiC or other networking OS. This software release is Centec's contribution to the open community of its implementation of the SAI 1.5.1 as specified on the SAI Github at https://github.com/opencomputeproject/SAI, and the SAI release supports the Centec CTC7132.
This software release also support some private features by Centec, not defined in SAI. See below tables.

- This SAI plugin requires Centec SDK support, so first step, you need to get Centec SDK for your switch chip, and copy them to $SAI_SOURCE_DIR/sdk
- To get SDK, please contact Centec.
- Prepare nessary directories: $SAI_SOURCE_DIR/lib/$chipname, and copy compiled libctcsdk.so to the directories.
$SAI_SOURCE_DIR/ctcsdk like this:
[centec@sw1 ctcsdk]$ ls
app core ctc_shell dkits driver Makefile Makefile.one_lib sal torvars.bat
cfg compile.bat ctccli dal docs libctccli Makefile.kernel Makefile.user mk script
You can modify the CMakeLists.txt following here: First we need to edit $SAI_SOURCE_DIR/CMakeLists.txt, which located in this folder. With this file, cmake can generate Makefile automatically. Here we give an example, which provides a switch box with x86 CPU and Centec CTC7132(TsingMa) switch chip:
SET(ARCH "board")
SET(CHIPNAME "tsingma")
SET(SDKHOME "../sdk/")
If you want to enable warmboot feature, you will be need redis support,and set below flag, and set the correct REDIS_INCLUDE_DIR.
SET(CONFIG_DBCLIENT 1)
If you want to enable direct SAI CLI feature, you will need to set below flag, use "sai get ..." or "sai set ...".
SET(CONFIG_SAICLI 1)
If you want to enable CTC SDK shell, you will need to set below flag, and use ctc_shell to connect and configure, ctc_shell need contact Centec to get.
SET(CONFIG_SHELLMODE 1)
After this, let us enter folder build/, and run these command:
[centec@sw0 build]$ rm -rf *
[centec@sw0 build]$ cmake ../
Then you can see we have Makefile now, and let us make it:
[centec@sw0 build]$ ls
app centec CMakeCache.txt CMakeFiles cmake_install.cmake db Makefile
[centec@sw0 build]$ make
Enter into lib/chipname/ folder, you can see these files here:
[centec@sw0 tsingma]$ ls
libctcsdk.so libdb.so.1 libsai.so.1 libsai.so.1.5
