T4240 sgmii ports to GbE switch

     we connect t4240's rgmii port (EC1) to a GbE PHY, it works properly, and we connect t4240's two sgmii ports (sg2.1,sg2.2 on serdes2) to a GbE switch,we can not access the cpu from RJ45_1 or RJ45_2, but the GbE switch seems works properly,because  we can communicate from RJ45_1 to RJ45_2 directly.



     we want to know how to config the sgmii ports?
