When set to on(1), the port will transmit to the line bridged frames (for which their secondary VLAN was 0xFFE internally). This is the case for ports connected to a station or to another switch that has no bridging capabilities. When set to off(2), the port will reject the bridged frames, by not sending them to the line. This is the case for ports connected to another switch that has its own bridging capabilities. Default value is on(1).
