        Moduletek has introducted the interface breakout and aggregate of switches to you. Now let me take  N3K-C3064PQ-10GE as an example, to show you how to configure the breakout and aggregate of the QSFP interface of CISCO NEXUS 3064 switches:
        1.  The default state of the device interface QSFP interface is in aggregate mode, view the interface can only see an independent 40G interface; 
        2. In global mode, execute the command “hardware profile portmode port_mode”, which configures all the interfaces of the device into a combination of interface mode.  Breakout /aggregate are using this command, you only need to change the options of the interface mode; when breakout an interface, the first interface is used as the starting interface by default. For example, breakout a QSFP interface, that is, the first QSFP interface, the test device for 49th port; then, breakouting two QSFP interfaces, that is, the first and second QSFP interfaces, the test device for the 49th and 50th ports; after the configuration of the interface mode , you need to save the startup configuration and reboot the device.
        3. When configured as a breakout interface, we will view the interface which originally independent of a single interface into four 10G interfaces.
