有关Interface，就不得不提Bond Bond将设备用多个连接在一起，形成一个虚拟的连接，从而实现高可用性以及高吞吐量 很多别名：LACP Trunk, Bond, Etherchannel LACP (Link Aggregation Control Protocol) [IMG] [IMG] bond_mode active-backup: 一个连接是active，其他的backup，当active失效的时候，backup顶上 balance-slb: 流量安装源MAC和output VLAN进行负载均衡 balance-tcp:必须在支持LACP协议的情况下才可以，可根据L2, L3, L4进行负载均衡 我们做个实验测试Bond [IMG] ovs-vsctl add-bond ubuntu_br bond0 first_br second_br ovs-vsctl add-bond helloworld bond1 first_if second_if ovs-vsctl set Port bond0 lacp=active ovs-vsctl set Port bond1 lacp=active [IMG] 查看Bond [IMG] 查看LACP root@popsuper1982:/home/openstack# ovs-appctl lacp/show ---- bond0 ---- status: active negotiated sys_id: 2a:96:0e:c7:85:49 sys_priority: 65534 aggregation key: 7 lacp_time: slow slave: first_br: current attached port_id: 7 port_priority: 65535 may_enable: true actor sys_id: 2a:96:0e:c7:85:49 actor sys_priority: 65534 actor port_id: 7 actor port_priority: 65535 actor key: 7 actor state: activity aggregation synchronized collecting distributing partner sys_id: 72:d2:d3:59:8c:41 partner sys_priority: 65534 partner port_id: 3 partner port_priority: 65535 partner key: 3 partner state: activity aggregation synchronized collecting distributing slave: second_br: current attached port_id: 8 port_priority: 65535 may_enable: true actor sys_id: 2a:96:0e:c7:85:49 actor sys_priority: 65534 actor port_id: 8 actor port_priority: 65535 actor key: 7 actor state: activity aggregation synchronized collecting distributing partner sys_id: 72:d2:d3:59:8c:41 partner sys_priority: 65534 partner port_id: 4 partner port_priority: 65535 partner key: 3 partner state: activity aggregation synchronized collecting distributing ---- bond1 ---- status: active negotiated sys_id: 72:d2:d3:59:8c:41 sys_priority: 65534 aggregation key: 3 lacp_time: slow slave: first_if: current attached port_id: 3 port_priority: 65535 may_enable: true actor sys_id: 72:d2:d3:59:8c:41 actor sys_priority: 65534 actor port_id: 3 actor port_priority: 65535 actor key: 3 actor state: activity aggregation synchronized collecting distributing partner sys_id: 2a:96:0e:c7:85:49 partner sys_priority: 65534 partner port_id: 7 partner port_priority: 65535 partner key: 7 partner state: activity aggregation synchronized collecting distributing slave: second_if: current attached port_id: 4 port_priority: 65535 may_enable: true actor sys_id: 72:d2:d3:59:8c:41 actor sys_priority: 65534 actor port_id: 4 actor port_priority: 65535 actor key: 3 actor state: activity aggregation synchronized collecting distributing partner sys_id: 2a:96:0e:c7:85:49 partner sys_priority: 65534 partner port_id: 8 partner port_priority: 65535 partner key: 7 partner state: activity aggregation synchronized collecting distributing 默认情况下bond_mode是active-backup模式，一开始active的是first_br和first_if 从192.168.100.100 ping 192.168.100.102，以及192.168.100.101 ping 192.168.100.103，都是从first_if通过 [IMG] 如果把first_if设成down，则包的走向会变 ip link set first_if down 发现second_if开始有流量，京first_if变成down, 192.168.100.100和192.168.100.101似乎没有收到影响 second_br和second_if变成active [IMG] 重启first_if，但是second_br和second_if仍然是active ip link set first_if up [IMG] 把bond_mode设为balance-slb ovs-vsctl set Port bond0 bond_mode=balance-slb ovs-vsctl set Port bond1 bond_mode=balance-slb 同时192.168.100.100 ping 192.168.100.102,192.168.100.101 ping 192.168.100.103, 已经分流了 把bond_mode设为balance-tcp ovs-vsctl set Port bond0 bond_mode=balance-tcp ovs-vsctl set Port bond1 bond_mode=balance-tcp 同时在192.168.100.100上：netperf -H 192.168.100.102 -t UDP_STREAM -- -m 1024 在192.168.100.101上： netperf -H 192.168.100.103 -t UDP_STREAM -- -m 1024 |
