ML2 Nexus MD Installation Install networking-cisco package as described in the section Installing the networking-cisco Package. Configure Nexus ML2 Driver. Once the networking-cisco code is installed, it needs to be configured and enabled in neutron, the Nexus Mechanism Driver Administration Guide provides full details on how to create the neutron configs for various use cases. For details on each configuration parameters, refer to Nexus Configuration Reference. Below is a simple VLAN configuration which can be applied to ML2 neutron config files ml2_conf.ini and possibly ml2_conf_cisco.ini located in directory /etc/neutron/plugins/ml2. The file ml2_conf_cisco.ini is optional if you’d like to isolate cisco specific parameters. [ml2] #- This neutron config specifies to use vlan type driver and use # cisco nexus mechanism driver. type_drivers = vlan tenant_network_types = vlan mechanism_drivers = openvswitch,cisco_nexus #- This extension driver must be enabled when the mechanism # driver includes nexus. extension_drivers = cisco_providernet_ext #- This neutron config specifies the vlan range to use. [ml2_type_vlan] network_vlan_ranges = physnet1:1400:3900 #- Provide Nexus credentials, OpenStack hostname, and nexus interface [ml2_mech_cisco_nexus:192.168.1.1] username=admin password=mySecretPasswordForNexus host_ports_mapping=host-1:[1/2] Restart neutron to pick-up configuration changes. $ service neutron-server restart
