Local bridging
Whenever possible, use local bridging to offload the CAPWAP tunnel. Note that in this case, Wi-Fi client devices obtain IP addresses from the same DHCP server as wired devices on the LAN. The vlan ID can only be configured from the CLI:
config wireless-controller vap
edit "vaplocalbridge"
set vdom "root"
set ssid "testvaplocalbridge"
set local-bridging enable
set vlanid 40 ---> only available in CLI
next
end
