Brocade ML2 Mechanism driver from ML2 plugin

ML2 plugin requires mechanism driver to support configuring of hardware switches. Brocade Mechanism for ML2 uses NETCONF at the backend to configure the Brocade switch. Currently the mechanism drivers support VLANs only.

Configuration

In order to use this mechnism the brocade configuration file needs to be edited with the appropriate configuration information:

    % cat /etc/neutron/plugins/ml2/ml2_conf_brocade.ini
    [switch]
    username = admin
    password = password
    address  = <switch mgmt ip address>
    ostype   = NOS
    physical_networks = phys1

Additionally the brocade mechanism driver needs to be enabled from the ml2 config file:

   % cat /etc/neutron/plugins/ml2/ml2_conf.ini

   [ml2]
   tenant_network_types = vlan
   type_drivers = local,flat,vlan,gre,vxlan
   mechanism_drivers = openvswitch,brocade
   # OR mechanism_drivers = openvswitch,linuxbridge,hyperv,brocade
   ...
   ...
   ...

Required L2 Agent

This mechanism driver works in conjunction with an L2 Agent. The agent should be loaded as well in order for it to configure the virtual network int the host machine. Please see the configuration above. Atleast one of linuxbridge or openvswitch must be specified.

Hardware L3 Router (SVI)

Brocade Hardaware supports SVI (Switch Virtual Interface) which provides ASIC level routing/gateway functionality in the switch for configured VLANs. This Service plugin provides support for this feature which enables line rate routing/gateway functionality.

l3_router_plugin.py provides a hardware based l3 router.
