Behavior of the “All APs on This Subnet” wireless client isolation option. 

 
As illustrated in the first figure when AP 1 and AP 2 are using the “This AP 
Only” option, wireless traffic between STA 1 and STA 2 is blocked by AP 1. 
While wireless traffic between STA 2 and STA 3, which are associated with 
different APs, is still allowed. If the “All APs in This Subnet” option is used as 
shown in second figure, AP 1 and AP 2 communicates with each other via an 
inter-AP protocol to share their STA association information to block wireless 
traffic among all the STAs.
