 Networking configuration options

The options and descriptions listed in this introduction are auto generated from the code in the Networking service project, which provides software-defined networking between VMs run in Compute. The list contains common options, while the subsections list the options for the various networking plug-ins.

Table 8.1. Description of common configuration options
Configuration option = Default value Description
[DEFAULT]
admin_password = None (StrOpt) Admin password

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.
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) The hostname Neutron is running on
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

[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.
