--------------------------------------------------------------------------------       sp-web@root/Tenant-A            ps-web@root/Tenant-A       default@root                    default@root           <<<>>>>       sp-web@root/Tenant-A            ps-web@root/Tenant-A

a. Virtual Machines are protected by VSG
b. Toggling of a given VM's port-profile from one to another belonging to same org and same VSG affects the binding of other VM(s)
c.  This happens momentarily and it recovers within few seconds of the Port-profile update. Traffic from or to the affected VM may get dropped for any new connections during the update window.
