Hi,
I was only able to find for S6720-EI.
S6720-30C-EI-24S-AC has default:1.9MB,enhanced mode:7.5MB

Can you please share the exact models and I'll try to find for those.

Hello friend
By default, the interface buffer is small. If the traffic burst on the interface reaches about 50%~60% of the interface bandwidth, packet loss occurs. There is no data to describe the cache size of all interfaces of a switch separately,you can use the display interface G 0/0/1 command to check the interface usage of each interface.

Dear @jason_hu,

But do you have a doc that inform what is the size of this buffer that is shared with all interfaces? I have to respond a RFI with a link of the doc. Client is asking if the equipment have at least 9MB of buffer.

Hi,

Not exactly public document but it is a document with restrictions for partners only. I had it downloaded, I'll try to find the link and will share here later today.
For other models, I've raised it with Huawei SEs and will share as I get the details.
