|
Connection can be initiated by the ovsdb server. The default value is |
|
Port number for L2 gateway agent, so that it can listen. The default value is |
|
The L2 gateway agent retries to connect to the OVSDB server. The default value is |
| L2 gateway agent OVSDB server list. |
|
The L2 gateway agent checks connection state with the OVSDB servers. The interval is number of seconds between attempts. The default value is |
|
Socket timeout. The default value is |
|
Default device name of the L2 gateway. The default value is |
|
Default interface name of the L2 gateway. The default value is |
|
The periodic interval at which the plugin. The default value is |
|
Backend to use as a service provider for L2 Gateway. The default value is |
|
Quota of the L2 gateway. The default value is |
|
Allow automatic l3-agent failover. The default value is |
| List of optional environment variables. |
| List of optional volumes to be mounted. |
|
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 |
| Name of Open vSwitch bridge to use. |
|
Domain to use for building the hostnames. The default value is |
|
Enable Distributed Virtual Router. The default value is |
|
Generate a wrapper script so OpenStack Networking (neutron) launches the dibbler client in a separate container. The default value is |
|
Generate a dnsmasq wrapper script so that OpenStack Networking (neutron) launches dnsmasq in a separate container. The default value is |
|
If True, DHCP always provides metadata route to VM. The default value is |
|
Generate a wrapper script so OpenStack Networking (neutron) launches haproxy in a separate container. The default value is |
|
If True, enable the internal OpenStack Networking (neutron) DNS server that provides name resolution between VMs. This parameter has no effect if NeutronDhcpAgentDnsmasqDnsServers is set. The default value is |
|
If True, DHCP allows metadata support on isolated networks. The default value is |
|
Generate a wrapper script so OpenStack Networking (neutron) launches keepalived processes in a separate container. 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 |
|
Generate a wrapper script so OpenStack Networking (neutron) launches radvd in a separate container. Note that is currently disabled by default pending availability of a fix to radvd (see https://bugzilla.redhat.com/show_bug.cgi?id=1564391). It will be enabled by default once the fix to radvd is generally available across target distributions. The default value is |
| 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 |
|
OpenStack Networking (neutron) DHCP Agent interface driver. The default value is |
|
Agent mode for L3 agent. Must be |
| Configure the classname of the firewall driver to use for implementing security groups. Possible values depend on system configuration. The default value of an empty string will result in a default supported configuration. |
|
A list of mappings of physical networks to MTU values. The format of the mapping is |
|
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 |
|
IP version used for all overlay network endpoints. The default value is |
| Name of Open vSwitch bridge to use. |
| The password for the OpenStack Networking (neutron) service and database account. |
|
Comma-separated list of enabled extension plugins. The default value is |
|
Puppet resource tag names that are used to generate configuration files with puppet. The default value is |
|
Number of ports allowed per tenant, and minus means unlimited. The default value is |
| Sets the number of RPC workers for the OpenStack Networking (neutron) service. If not specified, it’ll take the value of NeutronWorkers and if this is not specified either, the default value results in the configuration being left unset and a system-dependent default will be chosen (usually 1). |
|
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. Note that more workers creates a larger number of processes on systems, which results in excess memory consumption. |
|
Driver or drivers to handle sending notifications. The default value is |
| List of <physical_network>:<physical_interface> tuples mapping physical network names to agent’s node-specific physical network interfaces. Defaults to empty list. |
