remove default configuration and bridge ether2-master-local, ether6-master-local and wlan1.
ether3,4,5 set as master port to ether2-master-local.
ether7,8,9,10 set as master port to ether6-master-local.
your wan source can be any port.
Actually you’d better to switch the modem into transparent bridge mode and use your 2011 as the router. Then you wouldn’t need additional switch and will have full control over the traffic. Even in your case you don’t need a switch in between as the 2011 can do the same as already stated.
