Description of common configuration options

Configuration option = Default value	Description
[DEFAULT]

admin_tenant_name = None	(StrOpt) Admin tenant name
admin_user = None	(StrOpt) Admin username

auth_url = None	(StrOpt) Authentication URL
base_mac = fa:16:3e:00:00:00	(StrOpt) The base MAC address Neutron will use for VIFs
bind_host = 0.0.0.0	(StrOpt) The host IP to bind to
bind_port = 9696	(IntOpt) The port to bind to
core_plugin = None	(StrOpt) The core plugin Neutron will use
default_ipv4_subnet_pool = None	(StrOpt) Default IPv4 subnet-pool to be used for automatic subnet CIDR allocation
default_ipv6_subnet_pool = None	(StrOpt) Default IPv6 subnet-pool to be used for automatic subnet CIDR allocation
dhcp_agent_notification = True	(BoolOpt) Allow sending resource operation notification to DHCP agent
dhcp_agents_per_network = 1	(IntOpt) Number of DHCP agents scheduled to host a network.
dhcp_broadcast_reply = False	(BoolOpt) Use broadcast in DHCP replies
dhcp_confs = $state_path/dhcp	(StrOpt) Location to store DHCP server config files
dhcp_delete_namespaces = False	(BoolOpt) Delete namespace after removing a dhcp server.
dhcp_domain = openstacklocal	(StrOpt) Domain to use for building the hostnames
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq	(StrOpt) The driver used to manage the DHCP server.
dhcp_lease_duration = 86400	(IntOpt) DHCP lease duration (in seconds). Use -1 to tell dnsmasq to use infinite lease times.
dhcp_load_type = networks	(StrOpt) Representing the resource type whose load is being reported by the agent. This can be "networks", "subnets" or "ports". When specified (Default is networks), the server will extract particular load sent as part of its agent configuration object from the agent report state, which is the number of resources being consumed, at every report_interval.dhcp_load_type can be used in combination with network_scheduler_driver = neutron.scheduler.dhcp_agent_scheduler.WeightScheduler When the network_scheduler_driver is WeightScheduler, dhcp_load_type can be configured to represent the choice for the resource being balanced. Example: dhcp_load_type=networks
enable_services_on_agents_with_admin_state_down = False	(BoolOpt) Enable services on an agent with admin_state_up False. If this option is False, when admin_state_up of an agent is turned False, services on it will be disabled. Agents with admin_state_up False are not selected for automatic scheduling regardless of this option. But manual scheduling to such agents is available if this option is True.
endpoint_type = publicURL	(StrOpt) Network service endpoint type to pull from the keystone catalog
force_gateway_on_subnet = True	(BoolOpt) Ensure that configured gateway is on subnet. For IPv6, validate only if gateway is not a link local address. Deprecated, to be removed during the K release, at which point the check will be mandatory.
host = localhost	(StrOpt) Hostname to be used by the neutron server, agents and services running on this machine. All the agents and services running on this machine must use the same host value.
interface_driver = None	(StrOpt) The driver used to manage the virtual interface.
ip_lib_force_root = False	(BoolOpt) Force ip_lib calls to use the root helper
mac_generation_retries = 16	(IntOpt) How many times Neutron will retry MAC generation
max_allowed_address_pair = 10	(IntOpt) Maximum number of allowed address pairs
max_dns_nameservers = 5	(IntOpt) Maximum number of DNS nameservers

max_subnet_host_routes = 20	(IntOpt) Maximum number of host routes per subnet
memcached_servers = None	(ListOpt) Memcached servers or None for in process cache.
periodic_fuzzy_delay = 5	(IntOpt) Range of seconds to randomly delay when starting the periodic task scheduler to reduce stampeding. (Disable by setting to 0)
periodic_interval = 40	(IntOpt) Seconds between running periodic tasks
periodic_monitoring_interval = 5	(IntOpt) Periodic interval at which the plugin checks for the monitoring L2 gateway agent
report_interval = 300	(IntOpt) Interval between two metering reports
state_path = /var/lib/neutron	(StrOpt) Where to store Neutron state files. This directory must be writable by the agent.
vlan_transparent = False	(BoolOpt) If True, then allow plugins that support it to create VLAN transparent networks.
[AGENT]
check_child_processes_action = respawn	(StrOpt) Action to be executed when a child process dies
check_child_processes_interval = 60	(IntOpt) Interval between checks of child process liveness (seconds), use 0 to disable
root_helper = sudo	(StrOpt) Root helper application.
root_helper_daemon = None	(StrOpt) Root helper daemon application to use when possible.
[PROXY]
admin_password = None	(StrOpt) Admin password
admin_tenant_name = None	(StrOpt) Admin tenant name
admin_user = None	(StrOpt) Admin user
auth_region = None	(StrOpt) Authentication region

[heleos]
admin_password = None	(StrOpt) ESM admin password.
[keystone_authtoken]
memcached_servers = None	(ListOpt) Optionally specify a list of memcached server(s) to use for caching. If left undefined, tokens will instead be cached in-process.
