What is "wireless bandwidth per switch"?

[ozipin]

I've been out of the game for a while and—in addition to my other studies—I'm trying to familiarize myself with the current Cisco product line.

In reading up on the Catalyst 9200 line there is a spec listed on the data sheet: "Wireless bandwidth per switch: Up to 48 Gbps on 24-port and 48-port Gigabit Ethernet model"

Try as I might, I cannot find any further information. I saw a post where someone suggested that this is related to using a 9200 as a wireless controller. However the only documentation I can find regarding that capability does not list 9200s and says the feature is EoL anyway.

I'm really just curious. Thanks!

The 9200 series switches do not support working as Wireless controllers. See below link, and refer to table 8. it says N/A (not applicable).

Please note it says "Up to 48 Gbps".  

9200L does not support mGIG and this means all PoE ports are 1 Gbps only.  

• 24-port switches can support up to 24 x APs at 1 Gbps.  This equates to 24 Gbps. 
• 48-port switches can support up to 48 x APs at 1 Gbps.  And this is 48 Gbps.  

In reality, this statement is very "pedestrian" and every switch manufacturer can make this same "claim". 

Must be a slow day for the Sales Team and the author(s) want to put as many words as they could.

The "Wireless bandwidth per switch" for the C9200 refers to Fabric Enabled Wireless, which means if the Switch is on a Software Defined Access (SD-Access) deployment then the forwarding of Data Plane traffic for wireless users is performed right there on the Access Switch (the C9200) which has the APs directly connected to it, instead of having to send that wireless users traffic to a WLC. On the same row of that table on the Datasheet you see that for the C9200L it says "N/A", that is because the C9200L does not supports Fabric Enabled Wireless.
