Configuring OVSDB

Configuring OVSDB

Prerequisites

Before configuring the open vSwitch database (OVSDB) function on the device, complete the following task:
  • Ensure that the route between the device and the VMware NSX controller is reachable.
  • For details, see Configuring an SSL Policy.

    To improve network security, the OVSDB connection between the switch and the VMware NSX controller is established based on Secure Sockets Layer (SSL). Therefore, the SSL policy needs to be configured on the device.

NOTE:

The device can establish an OVSDB connection with the VMware NSX controller only, but cannot establish OVSDB connections with other controllers.

Procedure

  1. Run the system-view command to enter the system view.
  2. Run the ovsdb server command to enable the OVSDB function globally and enter the OVSDB-Server view.

    By default, the OVSDB function is disabled globally.

  3. (Optional) Run the set ovsdb-mac number number-value command to configure the number of unicast MAC addresses that are supported by the OVSDB database.

    By default, the OVSDB database supports a maximum of 32768 unicast MAC addresses.

  4. (Optional) Run the source ip ip-address command to change the source IP address of the device that establishes an OVSDB connection with the VMware NSX controller.

    By default, the device automatically uses the IP address of the egress on the route reaching the VMware NSX controller as the source IP address for OVSDB connection.

  5. Run the controller ip [ vpn-instance vpn-instance-name ] ip-address [ port port-number ] [ max-backoff backoff-interval ] [ inactivity-probe probe-interval ] commands to configure the IP address, port ID, retransmission interval, and OVSDB link detection period for the VMware NSX controller that establishes an OVSDB connection with the device.

    By default, the IP address of the VMware NSX controller that establishes an OVSDB connection with the device is not configured.

  6. Run the ssl ssl-policy policy-name command to configure the SSL policy used for OVSDB connection.

    By default, the SSL policy used for OVSDB connection is not configured.

  7. (Optional) Run the client ssl-verify peer command to configure SSL verification on the VMware NSX controller.

    By default, the device does not implement SSL verification on the VMware NSX controller.

  8. (Optional) Configure the OVSDB consistency reconciliation mechanism.
    1. Run the smooth time hh:mm:ss command to configure the start time of OVSDB consistency reconciliation.

      By default, OVSDB consistency reconciliation starts from 03:00:00 each day.

    2. Run the smooth enable command to enable OVSDB consistency reconciliation to ensure that the OVSDB-related data executed by the device is consistent with the data delivered by the VMware NSX controller.

      By default, OVSDB consistency reconciliation is disabled.

  9. Run the ovsdb server enable command to enable the device to proactively send an OVSDB connection request to the VMware NSX controller and then establish an OVSDB connection.

    By default, the device does not send any OVSDB connection requests to the VMware NSX controller.

    NOTE:
    • After the ovsdb server enable command is run, the following operations cannot be performed:
      • Run the source ip command to change the source IP address of the device that establishes an OVSDB connection with the VMware NSX controller.

      • Run the controller ip command to change the IP address, port ID, retransmission interval, and OVSDB link detection period for the VMware NSX controller that establishes an OVSDB connection with the device.

      • Run the ssl ssl-policy command to change the SSL policy used by the OVSDB connection.

      • Run the client ssl-verify peer command to change the configurations related to SSL verification on the VMware NSX controller.

      To change the preceding configurations, run the undo ovsdb server enable command to disconnect the OVSDB connection between the device and the VMware NSX controller and then run corresponding commands.
    • After the ovsdb server enable command is run, if the device needs to establish OVSDB connections with another controller cluster, you are advised to run the undo ovsdb server command to disable the OVSDB function globally, delete OVSDB-related configurations and data, and then reconfigure the OVSDB function.

  10. Run the commit to commit the configuration.
