Hi,

Is there a documented list of Broadcom (BRCM) ASICs supported by the latest publicly available Community SAI package?

Thanks.

Best regards,

Lewis

Does anyone know if there is a document listing the Broadcom ASICs supported by the latest publicly available Community SAI package? Thanks.

I believe you may found needed information under the link : https://sonic-net.github.io/SONiC/Supported-Devices-and-Platforms.html.

Good luck,

Ros

Hi Ros,

Thanks for the information.
This is also the method we use to infer which Broadcom ASICs are supported by the community SAI Debian package. However, we’ve found that it might not be entirely accurate, as we know that the AS5812-54X uses the Trident 2+ ASIC, which is not supported by community SAI.
If the platforms listed on that page are those that have been verified to have basic packet switching functionality, then the page should be sufficient to answer our question.
Could the people who update that page clarify the criteria for adding platforms to it?
Thanks,

/Lewis

Hello Lewis,

Assuming you have a BCM-based switch running SONiC and relying on the Community SAI, you can issue the 'bcmcmd "VER ALL" ' command to get the list of BCM ASIC supported by the SAI ("Chips" section of the output), then for each entry Google the ASIC model name or compare this list with the contents of this XLS spreadsheet : https://raw.githubusercontent.com/Broadcom-Network-Switching-Software/OpenBCM/refs/heads/master/sdk-6.5.22/RELDOCS/SDK-6.5.22-Device-Matrix.xlsx or with this list : https://raw.githubusercontent.com/netbootxyz/pciids/master/pciids.ipxe

Example :

admin@sonic:~$ bcmcmd "VER ALL"
VER ALL

[...]

According to the XLS spreadsheet and PCI-IDs list, this SAI supports the following ASICs :

BCM56640 = Triumph3

BCM56850 = Trident2 (not Trident2+ !!!)

BCM56340 = Helix4

BCM56960 = Tomahawk

BCM56970 = Tomahawk2

BCM56870 = Trident3

BCM56980 = Tomahawk3

BCM56370 = Helix5

BCM56275 = Hurricane4

BCM56770 = Maverick2

BCM56780 (+ BCM56782, BCM56784, BCM56785, BCM56786, BCM56787, BCM56788, BCM56789 ?) = Trident4

BCM56880 (+ BCM56881, BCM56883) = Trident4-x11

BCM56990 (+ BCM56991, BCM56992, BCM56993, BCM56996, BCM56997, BCM56998, BCM56999) = Tomahawk4

BCM78900 (+ BCM78902, BCM78903, BCM78905) = Tomahawk5

Hi,

Thanks for the information.

However, as I know, that bcmcmd “VER ALL” shows the ASICs supported by SDK, not those supported by SAI. What do you think?

Best regards,

Lewis

Hello Lewis,

I own an Edge-Core AS5812-54X/DCS208 switch (BCM56860 Trident2+ based switch) and had to get the appropriate SAI from Edge-Core since TD2+ ASIC is not supported by the community SAI :-(

FYI, this is the output of the "VER" command on the BCM Shell relying on their SAI. As you can see, the list of supported ASICs slightly differs from the one reported by the community SAI :

adm@sonic:~$ bcmcmd "VER"

Hi Ludovic,

Thanks for the information.

As far as I know, the older SDK version supports TD2+, but the newer SDK version used by Community SAI does not. FYI.

Best regards,

Lewis

Hello Lewis,

As far as I know the Community SAI never supported the Trident2+ ASIC (or at least, it has not supported it since 2021)... that's why we had to request a compatible SAI to Edge-Core.

Anyway, the venerable Trident2+ is actually a very old ASIC (announced in April 2015 - 10 years ago ! See https://people.ucsc.edu/~warner/Bufs/trident-II+.pdf), and since it's no more supported by the new Broadcom "HSDK", I assume it's reaching its end of life.

Regards,

Ludovic

Hello Ludovic,

Yes, Community SAI has never supported TD2+.

What I was trying to point out is that “VER” displays the ASICs supported by the SDK, not those supported by SAI.

Thanks.

Best regards,

Lewis
