主题: [ovs-discuss] help: about ovs bond configure



hi  everybody,
  I want to ask a question about ovs bond.please help me if you know it.
 i am a newbie for learning openvswitch,recently i got a problem when i config ovs bond.
 some detail as follow:
 my system version is centos7 ,kernel is 3.10.0-123.20.1.el7.x86_64. i already config physical switch LACP .
----
 [root at host26 network-scripts]# uname -r
3.10.0-123.20.1.el7.x86_64
[root at host26 network-scripts]# cat /etc/redhat-release 
CentOS Linux release 7.0.1406 (Core)‍
------
‍ I want to bind multiple network interfaces(such as  p2p1 and p3p1) together into a single,simultaneously‍
increasing the bandwidth and providing redundancy.‍
my config files is:
[root at host26 network-scripts]# less ifcfg-ovsbr0 
DEVICE=ovsbr0
ONBOOT=yes
BOOTPROTO=static
USERCTL=no
IPV6INIT=no
IPADDR=172.18.10.42        #another server  is  172.18.10.43
TYPE=OVSBridge
DEVICETYPE=ovs
HOTPLUG=no‍



[root at host26 network-scripts]# less ifcfg-bond0 
DEVICE=bond0
ONBOOT=yes
BOOTPROTO=none
USERCTL=no
IPV6INIT=no
OVS_BRIDGE=ovsbr0
TYPE=OVSBond
BOND_IFACES="p2p1 p3p1"
OVS_OPTIONS="bond_mode=balance-tcp lacp=active other_config:lacp-time=fast"
HOTPLUG=no‍



[root at host26 network-scripts]# less ifcfg-p2p1
DEVICE=p2p1
TYPE=Ethernet
ONBOOT=yes
HOTPLUG=no‍



[root at host26 network-scripts]# less ifcfg-p3p1
DEVICE=p3p1
TYPE=Ethernet
ONBOOT=yes
HOTPLUG=no‍



when i restart network


[root at host26 network-scripts]# ovs-vsctl show

my second server is 172.18.10.43, full same config as above just ip address!!


when i use iperf3 and ping to test the bandwidth,as follow:

i found the bandwidth is increasing,exceed one nic's throughput , but problem is coming.  when i down one of the physical nic,the network is interrupt about one minutes,in other words,it's can't providing redundancy normally,how can i change this config to ‍satisfy my ‍purpose.   ‍


I look forward to your early reply,thank you very much.‍


sincerely 

‍
