vACL - Installation Guide
============================
vACL Compilation
===================
After downloading (or doing a git clone) in a directory (samplevnf)
-------------
Dependencies
-------------
- DPDK supported versions ($DPDK_RTE_VER = 16.04, 16.11, 17.02 or 17.05): Downloaded and installed via vnf_build.sh or manually from [here] (http://fast.dpdk.org/rel/)
- libpcap-dev
- libzmq
- libcurl
---------------------
Environment variables
---------------------
Apply all the additional patches in 'patches/dpdk_custom_patch/' and build dpdk
::
export RTE_SDK=<dpdk directory>
export RTE_TARGET=x86_64-native-linuxapp-gcc
This is done by vnf_build.sh script.
Auto Build:
===========
$ ./tools/vnf_build.sh in samplevnf root folder
Follow the steps in the screen from option [1] --> [9] and select option [8]
to build the vnfs.
It will automatically download selected DPDK version and any required patches
and will setup everything and build vACL VNFs.
Following are the options for setup:
::
----------------------------------------------------------
Step 1: Environment setup.
----------------------------------------------------------
[1] Check OS and network connection
[2] Select DPDK RTE version
----------------------------------------------------------
Step 2: Download and Install
----------------------------------------------------------
[3] Agree to download
[4] Download packages
[5] Download DPDK zip
[6] Build and Install DPDK
[7] Setup hugepages
----------------------------------------------------------
Step 3: Build VNFs
----------------------------------------------------------
[8] Build all VNFs (vACL, vCGNAPT, vFW, UDP_Replay)
[9] Exit Script
An vACL executable will be created at the following location
samplevnf/VNFs/vACL/build/vACL
Manual Build:
=============
1. Download DPDK supported version from dpdk.org
- http://dpdk.org/browse/dpdk/snapshot/dpdk-$DPDK_RTE_VER.zip
2. unzip dpdk-$DPDK_RTE_VER.zip and apply dpdk patches only in case of 16.04
(Not required for other DPDK versions)
- cd dpdk
- patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-link-management.patch
- patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-Rx-hang-when-disable-LLDP.patch
- patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-link-status-change-interrupt.patch
- patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-VF-bonded-device-link-down.patch
- patch -p1 < $VNF_CORE/patches/dpdk_custom_patch/disable-acl-debug-logs.patch
- patch -p1 < $VNF_CORE/patches/dpdk_custom_patch/set-log-level-to-info.patch
- build dpdk
- make config T=x86_64-native-linuxapp-gcc O=x86_64-native-linuxapp-gcc
- cd x86_64-native-linuxapp-gcc
- make
- Setup huge pages
- For 1G/2M hugepage sizes, for example 1G pages, the size must be specified
explicitly and can also be optionally set as the default hugepage
size for the system. For example, to reserve 8G of hugepage memory
in the form of eight 1G pages, the following options should be passed
to the kernel:
* default_hugepagesz=1G hugepagesz=1G hugepages=8 hugepagesz=2M hugepages=2048
- Add this to Go to /etc/default/grub configuration file.
- Append "default_hugepagesz=1G hugepagesz=1G hugepages=8 hugepagesz=2M hugepages=2048"
to the GRUB_CMDLINE_LINUX entry.
3. Setup Environment Variable
- export RTE_SDK=<samplevnf>/dpdk
- export RTE_TARGET=x86_64-native-linuxapp-gcc
- export VNF_CORE=<samplevnf>
or using ./tools/setenv.sh
4. Build vACL VNFs
- cd <samplevnf>/VNFs/vACL
- make clean
- make
5. The vACL executable will be created at the following location
- <samplevnf>/VNFs/vACL/build/vACL
