ml2_conf.ini¶

DEFAULT¶

debug¶

Type: boolean
Default: false
Mutable: This option can be changed without restarting.

If set to true, the logging level will be set to DEBUG instead of the default INFO level.

log_config_append¶

Type: string
Default: <None>
Mutable: This option can be changed without restarting.

The name of a logging configuration file. This file is appended to any existing logging configuration files. For details about logging configuration files, see the Python logging module documentation. Note that when logging configuration files are used then all logging configuration is set in the configuration file and other logging configuration options are ignored (for example, log-date-format).

Deprecated Variations¶
Group	Name
DEFAULT	log-config
DEFAULT	log_config

log_date_format¶

Type: string
Default: %Y-%m-%d %H:%M:%S

Defines the format string for %(asctime)s in log records. Default: the value above . This option is ignored if log_config_append is set.

log_file¶

Type: string
Default: <None>

(Optional) Name of log file to send logging output to. If no default is set, logging will go to stderr as defined by use_stderr. This option is ignored if log_config_append is set.

Deprecated Variations¶
Group	Name
DEFAULT	logfile

log_dir¶

Type: string
Default: <None>

(Optional) The base directory used for relative log_file paths. This option is ignored if log_config_append is set.

Deprecated Variations¶
Group	Name

watch_log_file¶

Type: boolean
Default: false

use_syslog¶

Type: boolean
Default: false

Use syslog for logging. Existing syslog format is DEPRECATED and will be changed later to honor RFC5424. This option is ignored if log_config_append is set.

use_journal¶

List of network type driver entrypoints to be loaded from the neutron.ml2.type_drivers namespace.

tenant_network_types¶

Default network type for external networks when no provider attributes are specified. By default it is None, which means that if provider attributes are not specified while creating external networks then they will have the same type as tenant networks. Allowed values for external_network_type config option depend on the network type values configured in type_drivers config option.

overlay_ip_version¶

Type: integer
Default: 4

IP version of all overlay (tunnel) network endpoints. Use a value of 4 for IPv4 or 6 for IPv6.

ml2_type_flat¶

Comma-separated list of <vni_min>:<vni_max> tuples enumerating ranges of Geneve VNI IDs that are available for tenant network allocation

max_header_size¶

Type: integer
Default: 30

Geneve encapsulation header size is dynamic, this value is used to calculate the maximum MTU for the driver. The default size for this field is 30, which is the size of the Geneve header without any additional option headers.

ml2_type_gre¶

tunnel_id_ranges¶

Type: list
Default: ''

Comma-separated list of <tun_min>:<tun_max> tuples enumerating ranges of GRE tunnel IDs that are available for tenant network allocation

ml2_type_vlan¶

Type: list
Default: ''

Comma-separated list of <vni_min>:<vni_max> tuples enumerating ranges of VXLAN VNI IDs that are available for tenant network allocation

vxlan_group¶

ovs_driver¶

vnic_type_blacklist¶

Type: list
Default: ''

Comma-separated list of VNIC types for which support is administratively prohibited by the mechanism driver. Please note that the supported vnic_types depend on your network interface card, on the kernel version of your operating system, and on other factors, like OVS version. In case of ovs mechanism driver the valid vnic types are normal and direct. Note that direct is supported only from kernel 4.8, and from ovs 2.8.0. Bind DIRECT (SR-IOV) port allows to offload the OVS flows using tc to the SR-IOV NIC. This allows to support hardware offload via tc and that allows us to manage the VF by OpenFlow control plane using representor net-device.

Type: string
Default: <None>

Driver for security groups firewall in the L2 agent

enable_security_group¶

Type: boolean
