Chapter 14. Networking (neutron) Parameters
Parameter | Description |
---|---|
|
Database synchronization timeout default. The default value is: |
|
Enables DHCP agent notifications. The default value is: |
|
Remove configuration that is not generated by the director. Used to avoid configuration remnants after upgrades. The default value is: |
|
Comma-separated list of extensions enabled for the OpenStack Networking (neutron) agents. The default value is: |
|
Allow automatic l3-agent failover. The default value is: |
|
The logical to physical bridge mappings to use. The default ( |
|
The core plugin for networking. The value should be the entrypoint to be loaded from |
|
String of extra command line parameters to append to the |
| List of servers to use as dnsmasq forwarders. |
|
The number of DHCP agents to schedule per network. The default value is: |
|
Domain to use for building the hostnames. The default value is: |
|
Enable ARP responder feature in the OVS Agent. The default value is: |
|
Enable Distributed Virtual Router. The default value is: |
|
If True, DHCP always provides metadata route to VM. The default value is: |
|
If True, DHCP allows metadata support on isolated networks. The default value is: |
|
Enable/disable the L2 population feature in the OpenStack Networking (neutron) agents. The default value is: |
|
If True, DHCP provides metadata network. Requires either |
| Name of bridge used for external network traffic. Usually L2 agent handles port wiring into external bridge, and hence the parameter should be unset. |
|
Firewall driver for realizing OpenStack Networking (neutron) security group function. The default value is: |
|
Sets the flat network name to configure in plugins. The default value is: |
|
MTU of the underlying physical network. OpenStack Networking (neutron) uses this value to calculate MTU for all virtual network components. For flat and VLAN networks, OpenStack Networking uses this value without modification. For overlay networks such as VXLAN, OpenStack Networking automatically subtracts the overlay protocol overhead from this value. The default value is: |
|
Agent mode for L3 agent. Must be |
|
The mechanism drivers for the tenant network. The default value is: |
| Shared secret to prevent spoofing. |
|
The tenant network type. The default value is: |
|
The OpenStack Networking (neutron) ML2 and Open vSwitch VLAN mapping range to support. Defaults to permitting any VLAN on the |
|
Configure the classname of the firewall driver to use for implementing security groups. Possible values depend on system configuration. Some examples are: |
|
IP version used for all overlay network endpoints. The default value is: |
| The password for the OpenStack Networking (neutron) service and database account. |
|
Comma-separated list of enabled extension plugins. The default value is: |
|
Comma-separated list of service plugin entrypoints. The default value is: |
|
Comma-separated list of <tun_min>:<tun_max> tuples enumerating ranges of GRE tunnel IDs that are available for tenant network allocation. The default value is: |
|
The tunnel types for the tenant network. The default value is: |
|
Comma-separated list of network type driver entrypoints to be loaded. The default value is: |
|
Comma-separated list of <vni_min>:<vni_max> tuples enumerating ranges of VXLAN VNI IDs that are available for tenant network allocation. The default value is: |
| Sets the number of API and RPC workers for the OpenStack Networking service. The default value is equal to the number of CPU cores on the node. Note that more workers creates a larger number of processes on systems, which results in excess memory consumption. It is recommended to choose a suitable non-default value on systems with high CPU core counts. |
|
Driver or drivers to handle sending notifications. The default value is: |
