Chapter 8 Configure And Test Lacp Bonding With Open Vswitch Dpdk

To use Open vSwitch DPDK to configure and test LACP bonding, complete the following tasks: Configure the switch ports for LACP. Configure Linux kernel bonding for LACP as a baseline. Configure OVS DPDK bonding for LACP. Note. This topic describes switch configuration with a Dell S4048-ON switch.

Creating bonds of DPDK interfaces is slightly different to creating bonds of system interfaces. For DPDK, the interface type and devargs must be explicitly set. For example: $ ovs-vsctl add-bond br0 dpdkbond p0 p1 \ -- set Interface p0 type=dpdk options:dpdk-devargs=0000:01:00.0 \ -- set Interface p1 type=dpdk options:dpdk-devargs=0000:01:00.1.

Configure layer2 forwarding (testpmd) between bonded dev and a non bonded dev Uni-directional flow: Use IXIA to generate traffic to non bonded eth dev Verify that tx packet are evenly distrusted across active ports Measure performance through bonded eth dev Test with bonded port with 0, 1 and 2 slave ports. 115.11.

Using Open vSwitch with DPDK . This document describes how to use Open vSwitch with DPDK datapath. Important. Using the DPDK datapath requires building OVS with DPDK support. Refer to Open vSwitch with DPDK for more information. Ports and Bridges . ovs-vsctl can be used to set up bridges and other Open vSwitch features.

Bonding. . Bonding allows two or more interfaces, its members, to share network traffic. From a high-level point of view, bonded interfaces act like a single port, but they have the bandwidth of multiple network devices, e.g. two 1 GB physical interfaces act like a single 2 GB interface. Bonds also increase robustness: the bonded port ...

LACP Bonding LACP bonding requires the remote switch to implement LACP, but it is otherwise very simple in that, after LACP negotiation is complete, there is no need for special handling of received packets.

DPDK init arguments passed to the ovs-vswitchd as cmd line params ovs-vswitchd --dpdk -c 0x8 -n 4 --socket-mem 1024,0 ... Changed to optional OVSDB parameters with defaults ovs-vsctl set Open_vSwitch . other_config:dpdk-lcore-mask=0x8 ovs-vsctl set Open_vSwitch . other_config:dpdk-mem-channels=4

29.1. Link Bonding Modes Overview. Currently the Link Bonding PMD library supports following modes of operation: Round-Robin (Mode 0): Fig. 29.2 Round-Robin (Mode 0) This mode provides load balancing and fault tolerance by transmission of packets in sequential order from the first available member device through the last.

Feb 14, 2018 sudo ovs-vsctl ovs-vsctl set Open_vSwitch . . To configure OvS to use DPDK, enter the following command: sudo ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-init=true. Once the OvS is set up to use DPDK, we need to change one OvS setting and two important DPDK configuration settings. OvS Settings

2.1. Confirming OpenStack. Use the following commands to confirm OpenStack and OVS-DPDK configuration. 2.1.1. Show the Network Agents. Ensure that the value for Alive is True and State is UP for each agent. If there are any issues, view the logs in /var/log/neutron and /var/log/openvswitch/ovs-vswitchd.log to determine the issue.

114. Link Bonding for mode 4 (802.3ad) . This test plan is mainly to test link bonding mode 4 (802.3ad) function via testpmd. link bonding mode 4 is IEEE 802.3ad Dynamic link aggregation. Creates aggregation groups that share the same speed and duplex settings.

Apr 12, 2018 Test Configuration. Installing Docker and OvS-DPDK. Run the following commands to install Docker and OvS-DPDK. sudo apt install docker.io. sudo apt install openvswitch-switch-dpdk. After installing OvS-DPDK, we will update Ubuntu to use OvS-DPDK and restart the OvS service. sudo update-alternatives --set OvS-vswitchd /usr/lib/openvswitch-switch.

Oct 19, 2012 To fix this, you have two options. Change the command use to create the bond, so that LACP is enabled when the bond is created. Enable LACP after the bond is created. For option #1, youll simply append lacp=active to the command to create the bond, like so: ovs-vsctl add-bond ovsbr1 bond0 eth1 eth3 lacp=active.

Jan 17, 2023 Hugepages are required for DPDK. Instances leveraging DPDK-accelerated Open vSwitch must be configured to use hugepages by way of flavor attributes. Those attributes and the configuration of hugepages are described in this guide. CPU frequency should be set to maximum for optimal performance.

Dec 13, 2016 Public. Download PDF [1914 KB] This article explains the link aggregation feature of Data Plane Development Kit (DPDK) ports on Open vSwitch* (OVS), and shows how to configure them. Link aggregation can be used for high availability, traffic load balancing and extending the link capacity using multiple links/ports.

A: Firstly, you must have a DPDK-enabled version of Open vSwitch. If your version is DPDK-enabled it may support the dpdk_version and dpdk_initialized keys in the configuration database. Earlier versions of Open vSwitch only supported the other-config:dpdk-init key in the configuration in the database.
