SDN Controller

By adding an SDN controller, you can take over SDN networks of hardware switches to reduce network latencies and improve VXLAN network performances.
  • To add an SDN controller to the Cloud, plan for management networks in advance, and complete preparing the basic configurations for the SDN controller.
  • Currently, the Cloud only allows you to add an H3C SDN controller: VCFC.
    Note: If you use VCFC to configure hardware SDN, you need to configure the mapping between VLAN and VXLAN on VCFC in advance.

Add SDN Controller

In the navigation pane of the ZStack Private Cloud UI, choose Network Resource > SDN Controller. On the SDN Controller page, click Add SDN Controller. On the displayed Add SDN Controller page, set the following parameters:
  • Name: Enter a name for the SDN controller.
  • Description: Optional. Enter a description for the SDN controller.
  • Vendor: Select an SDN controller vendor. Currently, the Cloud only allows you to add H3C SDN controller: VCFC.
  • IP: Enter an IP address of the SDN controller.
  • User Name: Enter the user name of the SDN controller.
  • Password: Enter the password of the SDN controller.
  • Virtual Distributed Switch UUID: Enter a virtual distributed switch UUID.
    Note:
    • Make sure that you complete configuring a virtual distributed switch in the SDN controller in advance.
    • With this virtual distributed switch, an available VNI range of the hardware SDN VXLAN Pool can be determined.
You can add an SDN controller, as shown in Add SDN Controller.

SDN Controller Operations

You can perform the following operations on an SDN controller:
  • Change name: Change a name for the SDN controller.
  • Change description: Change a description of the SDN controller.
  • Delete: Delete the SDN controller. Exercise caution. If you delete the SDN controller, the hardware SDN VXLAN Pool associated with the SDN controller will be deleted as well. In this regard, all VXLAN networks under the VXLAN Pool and the L3 networks associated with the VXLAN networks will be deleted as well.
  • Audit: Check the related operations of the SDN controller.
