switches— The list of Cumulus Linux switches connected to the Neutron host. Specify a list of IP addresses.
scheme— The scheme (for example, HTTP) for the base URL for the ML2 API.
protocol_port— The protocol port for the bast URL for the ML2 API. The default value is 8000.
sync_time— A periodic time interval for polling the Cumulus Linux switch. The default value is 30 seconds.
spf_enable— Enables/disables SPF for the bridge. The default value is False.
new_bridge— Enables/disables VLAN-aware bridge mode for the bridge configuration. The default value is False, so a traditional mode bridge is created.
A demo involving OpenStack with Cumulus Linux is available in the Cumulus Networks knowledge base. It demonstrates dynamic provisioning of VLANs using a virtual simulation of two Cumulus VX leaf switches and two CentOS 7 (RDO Project) servers; collectively they comprise an OpenStack environment.
