測試網路聚合

1. 先查看 team0 兩張成員埠都正常運作。

   [root@kvm5 ~]# teamdctl team0 state
   setup:
     runner: activebackup
   ports:
     eth1
       link watches:
         link summary: up
         instance[link_watch_0]:
           name: ethtool
           link: up
     eth2
       link watches:
         link summary: up
         instance[link_watch_0]:
           name: ethtool
           link: up
   runner:
     active port: eth1
   

2. 經由 team0 成功 ping 192.168.122.1， team0 啟動可能會 delay，等一下再 ping 看看。

   [root@kvm5 ~]# ping -c4 -I team0 192.168.122.1
   PING 192.168.122.1 (192.168.122.1) from 192.168.122.15 team0: 56(84) bytes of data.
   
   --- 192.168.122.1 ping statistics ---
   4 packets transmitted, 0 received, 100% packet loss, time 3060ms
   
   [root@kvm5 ~]# ping -c4 -I team0 192.168.122.1
   PING 192.168.122.1 (192.168.122.1) from 192.168.122.15 team0: 56(84) bytes of data.
   64 bytes from 192.168.122.1: icmp_seq=1 ttl=64 time=0.584 ms
   64 bytes from 192.168.122.1: icmp_seq=2 ttl=64 time=0.340 ms
   64 bytes from 192.168.122.1: icmp_seq=3 ttl=64 time=0.308 ms
   64 bytes from 192.168.122.1: icmp_seq=4 ttl=64 time=0.278 ms
   
   --- 192.168.122.1 ping statistics ---

   rtt min/avg/max/mdev = 0.278/0.377/0.584/0.122 ms
   

3. 關閉 team0 的成員埠 team0-port1。

   [root@kvm5 ~]# nmcli connection down team0-port1
   Connection 'team0-port1' successfully deactivated (D-Bus active 
   path: /org/freedesktop/NetworkManager/ActiveConnection/128)
   

4. 查看 team0 只有成員埠 eth2，也就是 team0-port2 正常運作。

   [root@kvm5 ~]# teamdctl team0 state
   setup:
     runner: activebackup
   ports:
     eth2
       link watches:
         link summary: up
         instance[link_watch_0]:
           name: ethtool
           link: up
   runner:
     active port: eth2
   

5. 只有成員埠 team0-port2 正常運作，還是可以經由 team0 (192.168.122.15) 成功 ping 192.168.122.1。

   [root@kvm5 ~]# ping -I team0 192.168.122.1
   PING 192.168.122.1 (192.168.122.1) from 192.168.122.15 team0: 56(84) bytes of data.
   64 bytes from 192.168.122.1: icmp_seq=15 ttl=64 time=0.619 ms
   64 bytes from 192.168.122.1: icmp_seq=16 ttl=64 time=0.265 ms
   64 bytes from 192.168.122.1: icmp_seq=17 ttl=64 time=0.324 ms
   ^C
   --- 192.168.122.1 ping statistics ---
   17 packets transmitted, 3 received, 82% packet loss, time 16416ms
   rtt min/avg/max/mdev = 0.265/0.402/0.619/0.156 ms
   

6. 再啟動 team0 的成員埠 team0-port1。

   [root@kvm5 ~]# nmcli connection up team0-port1
   Connection successfully activated (D-Bus active path: 
   /org/freedesktop/NetworkManager/ActiveConnection/130)
   

7. 查看 team0 兩張成員埠都正常運作。

   [root@kvm5 ~]# teamdctl team0 state
   setup:
     runner: activebackup
   ports:
     eth1
       link watches:
         link summary: up
         instance[link_watch_0]:
           name: ethtool
           link: up
     eth2
       link watches:
         link summary: up
         instance[link_watch_0]:
           name: ethtool
           link: up
   runner:
     active port: eth2
