If OVS packages exist on the host, you must remove the existing packages and install the supported packages.

The supported Open vSwitch version is 2.9.1.8614397-1.

Procedure

  1. Verify the current version of the Open vSwitch installed on the host.

    ovs-vswitchd --version

    If you have a Open vSwitch newer or older version, you must replace that Open vSwitch version with the supported one.

    1. Delete the following Open vSwitch packages.
      • kmod-openvswitch

      • openvswitch

      • openvswitch-selinux-policy

    2. Install the NSX-T Data Center either from the NSX Manger or follow the manual installation procedure.
  2. Alternatively, upgrade the Open vSwitch packages required by NSX-T Data Center.
    1. Log in to the host as an administrator.
    2. Download and copy the nsx-lcp file into the /tmp directory.
    3. Untar the package.

      tar -zxvf nsx-lcp-<release>-rhel74_x86_64.tar.gz

    4. Navigate to the package directory.

      cd nsx-lcp-rhel74_x86_64/

    5. Replace existing Open vSwitch version with the supported one.
      • For newer Open vSwitch version, use the --nodeps command.

        For example, rpm -Uvh kmod-openvswitch-<new version>.e17.x86_64.rpm --nodeps

        rpm -Uvh openvswitch-*.rpm --nodeps

      • For older Open vSwitch version, use the --force command.

        For example, rpm -Uvh kmod-openvswitch-<new version>.e17.x86_64.rpm --nodeps --force

        rpm -Uvh openvswitch-*.rpm --nodeps --force
