7 UDP_Replay - Installation Guide
8 ============================
11 UDP_Replay Compilation
14 After downloading (or doing a git clone) in a directory (samplevnf)
17 * DPDK 16.04: Downloaded and installed via vnf_build.sh or manually from [here](http://fast.dpdk.org/rel/dpdk-16.04.tar.xz)
18 Both the options are available as part of vnf_build.sh below.
23 ###### Environment variables
25 Apply all the additional patches in 'patches/dpdk_custom_patch/' and build dpdk
28 export RTE_SDK=<dpdk 16.04 directory>
29 export RTE_TARGET=x86_64-native-linuxapp-gcc
31 This is done by vnf_build.sh script.
35 $ ./tools/vnf_build.sh in samplevnf root folder
37 Follow the steps in the screen from option [1] --> [8] and select option [7]
39 It will automatically download DPDK 16.04 and any required patches and will setup
40 everything and build UDP_Replay.
42 Following are the options for setup:
46 ----------------------------------------------------------
47 Step 1: Environment setup.
48 ----------------------------------------------------------
49 [1] Check OS and network connection
51 ----------------------------------------------------------
52 Step 2: Download and Install
53 ----------------------------------------------------------
56 [4] Download DPDK zip (optional, use it when option 4 fails)
60 ----------------------------------------------------------
62 ----------------------------------------------------------
67 An UDP_Replay executable will be created at the following location
68 samplevnf/VNFs/UDP_Replay/build/UDP_Replay
73 1. Download DPDK 16.04 from dpdk.org
74 - http://dpdk.org/browse/dpdk/snapshot/dpdk-16.04.zip
75 2. unzip dpdk-16.04 and apply dpdk patch
77 - patch -p0 < VNF_CORE/patches/dpdk_custom_patch/rte_pipeline.patch
78 - patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-link-management.patch
79 - patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-Rx-hang-when-disable-LLDP.patch
80 - patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-link-status-change-interrupt.patch
81 - patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-VF-bonded-device-link-down.patch
83 - make config T=x86_64-native-linuxapp-gcc O=x86_64-native-linuxapp-gcc
84 - cd x86_64-native-linuxapp-gcc
87 - For 1G/2M hugepage sizes, for example 1G pages, the size must be specified
88 explicitly and can also be optionally set as the default hugepage size for
89 the system. For example, to reserve 8G of hugepage memory in the form of
90 eight 1G pages, the following options should be passed to the kernel:
91 * default_hugepagesz=1G hugepagesz=1G hugepages=8 hugepagesz=2M hugepages=2048
92 - Add this to Go to /etc/default/grub configuration file.
93 - Append "default_hugepagesz=1G hugepagesz=1G hugepages=8 hugepagesz=2M hugepages=2048"
94 to the GRUB_CMDLINE_LINUX entry.
95 3. Setup Environment Variable
96 - export RTE_SDK=<samplevnf>/dpdk-16.04
97 - export RTE_TARGET=x86_64-native-linuxapp-gcc
98 - export VNF_CORE=<samplevnf>
99 or using ./toot/setenv.sh
100 4. Build UDP_Replay application
101 - cd <samplevnf>/VNFs/UDP_Replay
104 5. An UDP_Replay executable will be created at the following location
105 - <samplevnf>/VNFs/UDP_Replay/build/UDP_Replay
110 Setup Port to run VNF:
111 ----------------------
113 1. cd <samplevnf>/dpdk
114 3. ./tool/dpdk_nic_bind.py --status <--- List the network device
115 2. ./tool/dpdk_nic_bind.py -b igb_uio <PCI Port 0> <PCI Port 1>
116 .. _More details: http://dpdk.org/doc/guides-16.04/linux_gsg/build_dpdk.html#binding-and-unbinding-network-ports-to-from-the-kernel-modules
122 cd <samplevnf>/VNFs/UDP_Replay
123 ./build/UDP_Replay -c 0xf -n 4 -- -p 0x1 --config="(0,0,1)"
