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, logging_context_format_string).

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>

linux_bridge

physical_interface_mappings
Type:list
Default:u''

Comma-separated list of <physical_network>:<physical_interface> tuples mapping physical network names to the agent’s node-specific physical network interfaces to be used for flat and VLAN networks. All physical networks listed in network_vlan_ranges on the server should have mappings to appropriate interfaces on each agent.

securitygroup

firewall_driver
Type:string
Default:<None>

Driver for security groups firewall in the L2 agent

enable_security_group
Type:boolean
Default:true

Controls whether the neutron security group API is enabled in the server. It should be false when using no security groups or using the nova security group API.

enable_ipset
Type:boolean
Default:true

Use ipset to speed-up the iptables based security groups. Enabling ipset support requires that ipset is installed on L2 agent node.

permitted_ethertypes
Type:list
Default:u''

Comma-separated list of ethertypes to be permitted, in hexadecimal (starting with “0x”). For example, “0x4008” to permit InfiniBand.

vxlan

enable_vxlan
Type:boolean
Default:true

Enable VXLAN on the agent. Can be enabled when agent is managed by ml2 plugin using linuxbridge mechanism driver

ttl
Type:integer
Default:<None>

TTL for vxlan interface protocol packets.

tos
Type:integer
Default:<None>

TOS for vxlan interface protocol packets. This option is deprecated in favor of the dscp option in the AGENT section and will be removed in a future release. To convert the TOS value to DSCP, divide by 4.

Warning

This option is deprecated for removal. Its value may be silently ignored in the future.

vxlan_group
Type:string
Default:224.0.0.1

Multicast group(s) for vxlan interface. A range of group addresses may be specified by using CIDR notation. Specifying a range allows different VNIs to use different group addresses, reducing or eliminating spurious broadcast traffic to the tunnel endpoints. To reserve a unique group for each possible (24-bit) VNI, use a /8 such as 239.0.0.0/8. This setting must be the same on all the agents.

local_ip
Type:ip address
Default:<None>

IP address of local overlay (tunnel) network endpoint. Use either an IPv4 or IPv6 address that resides on one of the host network interfaces. The IP version of this value must match the value of the ‘overlay_ip_version’ option in the ML2 plug-in configuration file on the neutron server node(s).

udp_srcport_min
Type:port number
Default:0
Minimum Value:0
Maximum Value:65535

The minimum of the UDP source port range used for VXLAN communication.

udp_srcport_max
Type:port number
Default:0
Minimum Value:0
Maximum Value:65535

The maximum of the UDP source port range used for VXLAN communication.

udp_dstport
Type:port number
Default:<None>
Minimum Value:0
Maximum Value:65535

The UDP port used for VXLAN communication. By default, the Linux kernel doesn’t use the IANA assigned standard value, so if you want to use it, this option must be set to 4789. It is not set by default because of backward compatibiltiy.

l2_population
Type:boolean
Default:false

Extension to use alongside ml2 plugin’s l2population mechanism driver. It enables the plugin to populate VXLAN forwarding table.

arp_responder
Type:boolean
Default:false

Enable local ARP responder which provides local responses instead of performing ARP broadcast into the overlay. Enabling local ARP responder is not fully compatible with the allowed-address-pairs extension.

multicast_ranges
Type:list
Default:u''

Optional comma-separated list of <multicast address>:<vni_min>:<vni_max> triples describing how to assign a multicast address to VXLAN according to its VNI ID.
