Data Center Feature - DCB

Does RG-S6200 support DCB and DCBx? I am trying to find command guides and I cannot find the DCB protocol.
I found an old document from 6900 that has DCB https://www.ruijie.com/en-global/resources/preview/76701/ but later versions of 6900 has no more DCB included.
Other brands have DCB stated on their command guides or datasheets, so I am confused why Ruijie doesn't have it.
Thank you.

Edit: I am asking this because older Ruijie models have DCB and DCBx from their datasheet or command guides but on the newer models I cannot find anything. The specific model I am inquiring is RG-S6250-48XS8CQ from the newer RG-S6200 series. Thank you!

Sir, I checked the datasheet, and it supports DCBX.

Hello, thank you for the reply. I meant the latest Ruijie model from RG-S6200 series, RG-S6250-48XS8CQ. The one from the screenshot is an older model from 2013. That's why I was wondering why there is DCB on older models but nothing on the newer models.
