Default behavior is local breakout of data traffic at AP. Only management and control traffic is carried to Pronto Cloud Controller. If required, the bearer data traffic (or any layer 2 traffic) can be tunneled till Pronto Cloud Controller through L2oGRE tunnel. Pronto Cloud Controller can configure endpoint of GRE tunnel and choose which traffic should be sent through the tunnel. Both VLAN and non VLAN traffic can be sent through the tunnel.
