CAPsMAN and config Channel Width (Local forwarding)

Hi,

I use CAPsMAN to manage the wireless network.
In Datapath I activated “Local forwarding”
How can I now config the Channel width?
I think it is now not ok. Users can’t get high speed WiFi now.

Pease explain

In order to set the wireless band, extension channel, bandwidth, it should be set with the following items.
