RPC has a version of itself. In Neutron a plugin implements several RPC interface, so a single RPC version doesn't work. In Mixin callback class approach, RPC versioning depends on each plugin implementation and it makes harder to maintain RPC version appropriately. This patch series replaces mixin RPC callback of server side with a separate class. This commit handles server-side callback of security group RPC interface. * The server-side callback of Security group RPC is moved to api/rpc/handler and db/securitygroups_rpc_base now only contains a mixin class to add agent-based security group implementation with db operations. * get_port_from_device method in server-side callback class is moved to a mixin class of plugin implementation (SecurityGroupServerRpcMixin) because it involves DB lookup and is tightly coupled with plugin implementation rather than RPC interface definition. Most unit tests for SGServerRpcCallBackTestCase were skipped in the base class before, but now they are no longer skipped. The following items will be planned in later patches to avoid drastic changes in a single patch. * Merge security group RPC API and agent callback classes in agent/securitygroups_rpc into api/rpc/handlers/securitygroup_rpc * Remove completely duplicated db access code in get_port_from_device and get_port_and_sgs Partial-Bug: #1359416 Change-Id: Ia6535217d2e3b849a95667c1b53dd09675002892 |

Brocade Openstack Neutron Plugin
-
up-to-date version of these instructions are located at: http://wiki.openstack.org/brocade-neutron-plugin
-
N.B.: Please see Prerequisites section regarding ncclient (netconf client library)
-
Supports VCS (Virtual Cluster of Switches)
Openstack Brocade Neutron Plugin implements the Neutron v2.0 API.
This plugin is meant to orchestrate Brocade VCS switches running NOS, examples of these are:
- VDX 67xx series of switches
- VDX 87xx series of switches
Brocade Neutron plugin implements the Neutron v2.0 API. It uses NETCONF at the backend to configure the Brocade switch.

Directory Structure
Normally you will have your Openstack directory structure as follows:
/opt/stack/nova/
/opt/stack/horizon/
...
/opt/stack/neutron/neutron/plugins/
Within this structure, Brocade plugin resides at:
/opt/stack/neutron/neutron/plugins/brocade
Prerequsites
This plugin requires installation of the python netconf client (ncclient) library:
ncclient v0.3.1 - Python library for NETCONF clients available at http://github.com/brocade/ncclient
% git clone https://www.github.com/brocade/ncclient % cd ncclient; sudo python ./setup.py install
Configuration
-
Specify to Neutron that you will be using the Brocade Plugin - this is done by setting the parameter core_plugin in Neutron:
core_plugin = neutron.plugins.brocade.NeutronPlugin.BrocadePluginV2
-
Physical switch configuration parameters and Brocade specific database configuration is specified in the configuration file specified in the brocade.ini files:
% cat /etc/neutron/plugins/brocade/brocade.ini [SWITCH] username = admin password = password address = <switch mgmt ip address> ostype = NOS [database] connection = mysql://root:pass@localhost/brocade_neutron?charset=utf8 (please see list of more configuration parameters in the brocade.ini file)
Running Setup.py
Running setup.py with appropriate permissions will copy the default configuration file to /etc/neutron/plugins/brocade/brocade.ini. This file MUST be edited to suit your setup/environment.
% cd /opt/stack/neutron/neutron/plugins/brocade
% python setup.py
Devstack
Please see special notes for devstack at: http://wiki.openstack.org/brocade-neutron-plugin
In order to use Brocade Neutron Plugin, add the following lines in localrc, if localrc file doe not exist create one:
ENABLED_SERVICES=g-api,g-reg,key,n-api,n-crt,n-obj,n-cpu,n-net,n-cond,cinder,c-sch,c-api,c-vol,n-sch,n-novnc,n-xvnc,n-cauth,horizon,rabbit,neutron,q-svc,q-agt Q_PLUGIN=brocade
As part of running devstack/stack.sh, the configuration files is copied as:
% cp /opt/stack/neutron/etc/neutron/plugins/brocade/brocade.ini /etc/neutron/plugins/brocade/brocade.ini
(hence it is important to make any changes to the configuration in: /opt/stack/neutron/etc/neutron/plugins/brocade/brocade.ini)
