Manila Network Plugins: Configurable Neutron Port Binding Network Plugin¶

Configurable Neutron Port Binding Network Plugin: This plugin is very similar to the configurable neutron network plugin, the only difference is that this plugin can enforce port-binding. Port binding profiles from the manila configuration file are sent to Neutron at the time of creating network ports for the purpose of creating ONTAP LIFs. This allows network agents to bind the ports based off these profiles. When using multiple top of the rack switches to connect different compute nodes, this plugin is also capable of performing Hierarchical Port Binding. Share networks can be defined with VLAN shared provider networks or VLAN tenant networks. Administrators are required to define one or more binding profiles in manila.conf per backend configured with this plugin. Manila consumes bound network ports and invokes the NetApp driver to create LIFs assigned to the network segment and IP address as chosen.

Tenants must specify Neutron network information when creating share network objects. Manila will derive values for segmentation protocol, IP address, netmask and gateway from Neutron when creating a new share server..

In spirit this plugin works exactly like the Simple Neutron Port Binding Network Plugin. The only difference being that the Neutron network is not configured within manila.conf by the administrator. Use of this plugin allows Manila to derive network information from the Share Network objects created by the tenants. To set up the configurable Neutron port binding network plugin, the following options should be added to the driver-specific stanza within the Manila configuration file (manila.conf). The Neutron binding profile in this example is for a Cisco Nexus 9000 switch:

network_api_class = manila.network.neutron.neutron_network_plugin.NeutronBindNetworkPlugin
neutron_host_id = netapp_lab42
neutron_vnic_type = baremetal
neutron_binding_profiles = phys1

[phys1]
neutron_switch_id = 10.63.152.254
neutron_port_id = 1/1-4
neutron_switch_info = switch_ip:10.63.152.254

The following table lists the configuration options available for the configurable Neutron Port Binding network plugin:
