Prerequisites

• RDO install OpenStack Icehouse for CentOS6.5
• Install the ncclient Python library for NETCONF client (see https://github.com/leopoul/ncclient) on the Neutron server

Directory Structure

The Huawei Switch ML2 Driver can be downloaded from the repository located at:

https://github.com/huaweiswitch/neutron

(see https://github.com/huaweiswitch/neutron)

This repository represents code that will be put into the huawei directory as:

/master/neutron/plugins/ml2/drivers/huawei

Configuration

Huawei Driver configuration

• Edit /etc/neutron/neutron.conf:

core_plugin = ml2

• Edit /etc/neutron/plugins/ml2/ml2_conf.ini:

type_drivers = vlan
tenant_network_types = vlan
mechanism_drivers = openvswitch,huawei

• Edit /etc/neutron/plugins/ml2/ml2_conf_huawei.ini:

hostaddr = 192.168.0.1
username = admin
password = password
portname = 10GE1/0/1

• Start the neutron service by providing the relevant configuration files:

cd <neutron_path> && python <neutron_path>/bin/neutron-server --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini --config-file /etc/neutron/plugins/ml2/ml2_conf_huawei.ini

• Finally, restart neutron-server:

service neutron-server restart
