Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/vmware-nsx" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

    NSX|v service insertion handle upgrade

    When the service insertion is first enabled, and a security group is created,
    the plugin should do 2 things to allow the user to start working with service
    insertion immediately:
    1. Add all the current compute ports (VMs) to service insertion security group.
    2. Depending on the configuration, the driver will create any->any flow classifier entry,
       and any->any redirect rule at the backend so all the traffic will be redirected
       to the security partner.

    DocImpact: new nsxv configuration: service_insertion_redirect_all
    In True the plugin will create a rule to redirect all the traffic to the security partner.
