Neutron ML2 Cisco Nexus Mechanism Driver README Notes: The initial version of this driver supports only a single physical network. For provider networks, extended configuration options are not currently supported. This driver's database may have duplicate entries also found in the core ML2 database. Since the Cisco Nexus DB code is a port from the plugins/cisco implementation this duplication will remain until the plugins/cisco code is deprecated. For more details on using Cisco Nexus switches under ML2 please refer to: http://wiki.openstack.org/wiki/Neutron/ML2/MechCiscoNexus
