Hi, I have been searching high and low but have been unable to find information about these commands. If anyone could point me in the right direction it would be much appreciated. Thank you.

bridge-group 1 block-unknown-source

bridge-group 1 source-learning

bridge-group 1 unicast-flooding

bridge-group 1 block-unknown-source says Dott11 radio to block the clients taht are not registered with the AP, bridge-group 1 source-learning makes the AP not learn the source address of the cleint

That's what I thought, but how don't these two commands contradict one another?
