agent_boot_time
¶Type: | integer |
---|---|
Default: | 180 |
Delay within which agent is expected to update existing ports when it restarts. This option is deprecated in favor of direct RPC restart state transfer and will be removed in a future release.
Warning
This option is deprecated for removal since Stein. Its value may be silently ignored in the future.
type_drivers
¶Type: | list |
---|---|
Default: | local,flat,vlan,gre,vxlan,geneve |
List of network type driver entrypoints to be loaded from the neutron.ml2.type_drivers namespace.
tenant_network_types
¶Type: | list |
---|---|
Default: | local |
Ordered list of network_types to allocate as tenant networks. The default value ‘local’ is useful for single-box testing but provides no connectivity between hosts.
mechanism_drivers
¶Type: | list |
---|---|
Default: | u'' |
An ordered list of networking mechanism driver entrypoints to be loaded from the neutron.ml2.mechanism_drivers namespace.
extension_drivers
¶Type: | list |
---|---|
Default: | u'' |
An ordered list of extension driver entrypoints to be loaded from the neutron.ml2.extension_drivers namespace. For example: extension_drivers = port_security,qos
path_mtu
¶Type: | integer |
---|---|
Default: | 0 |
Maximum size of an IP packet (MTU) that can traverse the underlying physical network infrastructure without fragmentation when using an overlay/tunnel protocol. This option allows specifying a physical network MTU value that differs from the default global_physnet_mtu value.
physical_network_mtus
¶Type: | list |
---|---|
Default: | u'' |
A list of mappings of physical networks to MTU values. The format of the mapping is <physnet>:<mtu val>. This mapping allows specifying a physical network MTU value that differs from the default global_physnet_mtu value.
external_network_type
¶Type: | string |
---|---|
Default: | <None> |
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.
flat_networks
¶Type: | list |
---|---|
Default: | * |
List of physical_network names with which flat networks can be created. Use default ‘*’ to allow flat networks with arbitrary physical_network names. Use an empty list to disable flat networks.
vni_ranges
¶Type: | list |
---|---|
Default: | u'' |
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. This is the sum of the sizes of the outer ETH + IP + UDP + GENEVE header sizes. The default size for this field is 50, which is the size of the Geneve header without any additional option headers.
tunnel_id_ranges
¶Type: | list |
---|---|
Default: | u'' |
Comma-separated list of <tun_min>:<tun_max> tuples enumerating ranges of GRE tunnel IDs that are available for tenant network allocation
network_vlan_ranges
¶Type: | list |
---|---|
Default: | u'' |
List of <physical_network>:<vlan_min>:<vlan_max> or <physical_network> specifying physical_network names usable for VLAN provider and tenant networks, as well as ranges of VLAN tags on each available for allocation to tenant networks.
vni_ranges
¶Type: | list |
---|---|
Default: | u'' |
Comma-separated list of <vni_min>:<vni_max> tuples enumerating ranges of VXLAN VNI IDs that are available for tenant network allocation
vxlan_group
¶Type: | string |
---|---|
Default: | <None> |
Multicast group for VXLAN. When configured, will enable sending all broadcast traffic to this multicast group. When left unconfigured, will disable multicast VXLAN mode.
vnic_type_blacklist
¶Type: | list |
---|---|
Default: | u'' |
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.
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.
vnic_type_blacklist
¶Type: | list |
---|---|
Default: | u'' |
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. In case of sriov mechanism driver the valid VNIC types are direct, macvtap and direct-physical.
