Ethernet Interface Configuration
|
|
================================
|
|
|
|
You can review and modify the configuration for physical or virtual Ethernet
|
|
interfaces using the OpenStack Horizon Web interface or the CLI.

Physical Ethernet Interfaces
|
|
----------------------------
|
|
|
|
The physical Ethernet interfaces on |prod-os| nodes are configured to use the
|
|
following networks:
|
|
|
|
.. _ethernet-interface-configuration-ul-lk1-b4j-zq:
|
|
|
|
- the internal management network
|
|
|
|
- the internal cluster host network \(by default sharing the same L2
|
|
interface as the internal management network\)
|
|
|
|
- the external |OAM| network
|
|
|
|
- one or more data networks
|
|
|
|
A single interface can optionally be configured to support more than one
|
|
network using |VLAN| tagging \(see :ref:`Shared (VLAN or Multi-Netted) Ethernet
|
|
Interfaces
|
|
<network-planning-shared-vlan-or-multi-netted-ethernet-interfaces>`\).
|
|
|

.. _ethernet-interface-configuration-section-N10059-N1001C-N10001:

|
|
Virtual Ethernet Interfaces
|
|
---------------------------
|
|
|
|
The virtual Ethernet interfaces for guest |VMs| running on |prod-os| are
|
|
defined when an instance is launched. They connect the |VM| to project
|
|
networks, which are virtual networks defined over data networks, which in turn
|
|
are abstractions associated with physical interfaces assigned to physical
|
|
networks on the compute nodes.
|
|
|
|
The following virtual network interfaces are available:
|
|
|
|
.. _ethernet-interface-configuration-ul-amy-z5z-zs:
|
|
|
|
- |AVP|
|
|
|
|
- ne2k\_pci \(NE2000 Emulation\)
|
|
|
|
- pcnet \(AMD PCnet/|PCI| Emulation\)
|
|
|
|
- rtl8139 \(Realtek 8139 Emulation\)
|
|
|
|
- virtio \(VirtIO Network\)
|
|
|
|
- pci-passthrough \(|PCI| Passthrough Device\)
|
|
|
|
- pci-sriov \(|SRIOV| device\)
|
|
|
|
|
|
Unmodified guests can use Linux networking and virtio drivers. This provides a
|
|
mechanism to bring existing applications into the production environment
|
|
immediately.
|
|
|
|
.. xbooklink For more information about |AVP| drivers, see OpenStack VNF Integration: :ref:`Accelerated Virtual Interfaces <accelerated-virtual-interfaces>`.
|
|
|
|
|prod-os| incorporates |DPDK|-Accelerated Neutron Virtual Router L3 Forwarding
|
|
\(AVR\). Accelerated forwarding is used for directly attached project networks
|
|
and subnets, as well as for gateway, |SNAT| and floating IP functionality.
|
|
|
|
|prod-os| also supports direct guest access to |NICs| using |PCI| passthrough
|
|
or |SRIOV|, with enhanced |NUMA| scheduling options compared to standard
|
|
OpenStack. This offers very high performance, but because access is not managed
|
|
by |prod-os| or the vSwitch process, there is no support for live migration,
|
|
|prod-os|-provided |LAG|, host interface monitoring, |QoS|, or ACL. If |VLANs|
|
|
are used, they must be managed by the guests.
|
|
|
|
For further performance improvements, |prod-os| supports direct access to
|
|
|PCI|-based hardware accelerators, such as the Coleto Creek encryption
|
|
accelerator from Intel. |prod-os| manages the allocation of |SRIOV| VFs to
|
|
|VMs|, and provides intelligent scheduling to optimize |NUMA| node affinity.
