Hi,

 

 We want to interface an interface external ethernet switch to IMX6Q using RGMII interface . I have gone through forums here for clocking requirements . But I wanted to know is  since there is only a single interface to the processor from external switch , the data rate is limited to speed of the interface with the processor .

 

For eg: Even if there are 3 ports in the switch in rgmii mode , the maximum data rate for the traffic concerning the host processor is always 1 gbps and not 3 gbps . Please let me know if my understanding is correct ??
