OVS 개요

---

 

Linux의 상단에서 가상의 L2 Switch를 생성합니다. 정교한 패킷 제어 기능을 제공하는 OpenFlow 프로토콜을 지원 합니다.

 

• NetFlow, sFlow, SPAN, RSPAN, CLI, LACP, 802.1ag 지원

• OpenFlow

 
 

Open vSwitch 설치

---

 

Source로 설치

 

• RPM 생성을 위한 환경 구성

  • 참고 : [CentOS RPM 제작](CentOS.md#RPM 제작.md)

 
 

 yum install -y rpm-build
 yum groupinstall -y "Development Tools"
 
 yum install -y openssl-devel
 yum install kernel-devel
 
 mkdir -p $HOME/rpmbuild/SOURCES

 

• [CentOS 7](CentOS 7.md)에서 Open vSwitch 설치

 
 

 $HOME/rpmbuild/SOURCES/
 wget [http://openvswitch.org/releases/openvswitch-2.3.0.tar.gz](http://openvswitch.org/releases/openvswitch-2.3.0.tar.gz)
 tar xvfz openvswitch-2.3.0.tar.gz
 cd openvswitch-2.3.0
 
 vi rhel/openvswitch.spec
  ### Requires: openvswitch-kmod, logrotate, python
  Requires: logrotate, python
 
 rpmbuild -bb -D `uname -r` rhel/openvswitch.spec
 ### rpmbuild -bb rhel/openvswitch.spec
 ### rpmbuild -bb rhel/openvswitch-kmod-rhel6.spec
 
 cd $HOME/rpmbuild/RPMS/x86_64
 ls -alF
 
 yum localinstall openvswitch-2.3.0-1.x86_64.rpm

 

RPM으로 설치

wget [http://cbs.centos.org/kojifiles/packages/openvswitch/2.3.1/2.el7/x86_64/openvswitch-2.3.1-2.el7.x86_64.rpm](http://cbs.centos.org/kojifiles/packages/openvswitch/2.3.1/2.el7/x86_64/openvswitch-2.3.1-2.el7.x86_64.rpm)                    
rpm -ivh openvswitch-2.3.1-2.el7.x86_64.rpm
  
vi /etc/sysconfig/openvswitch

service openvswitch restart

 

OVS 명령어

Bridge와 Port 설정

ovs-vsctl add-br br0                  #--- br0 Bridge 추가
ovs-vsctl del-br br0                  #--- br0 Bridge 삭제
ovs-vsctl list-br
1.  vi /etc/sysconfig/network-scripts/ifcfg-br0  
  
ovs-vsctl set bridge br0 stp_enable=true     #--- STP 활성화
  
ovs-vsctl add-port br0 eth0           #--- br0 Bridge에 eth0 NIC 연결
ovs-vsctl del-port br0 eth0
ovs-vsctl list-ports br0
​# ethtool -K eth0 gro off
  
newview
ovs-vsctl show                        #--- Bridge 상세 조회
