我在centos5.5中创建了一个bonding接口，模式为balance-rr，使用从属eth6和eth7，eth6和eth7连接正常，配置文件如下：
[root@50:B3:42:00:00:A3 network-scripts]# cat ifcfg-bond1
DEVICE=bond1
IPADDR=172.16.252.225
NETMASK=255.255.0.0
GATEWAY=172.16.0.1
MTU=9000
ONBOOT==yes
BOOTPROTO=none
USERCTL=on
BONDING_OPTS="mode=balance-rr miimon=100"
[root@50:B3:42:00:00:A3 network-scripts]# cat ifcfg-eth6
DEVICE=eth6
USERCTL=no
ONBOOT=yes
MASTER=bond1
SLAVE=yes
BOOTPROTO=none
[root@50:B3:42:00:00:A3 network-scripts]# cat ifcfg-eth7
DEVICE=eth7
USERCTL=no
ONBOOT=yes
MASTER=bond1
SLAVE=yes
BOOTPROTO=none
并且bonding接口创建成功，sysfs中的参数为：
[root@50:B3:42:00:00:A3 network-scripts]# cat /sys/class/net/bond1/bonding/slaves
eth6 eth7
[root@50:B3:42:00:00:A3 network-scripts]# cat /sys/class/net/bond1/bonding/mode
balance-rr 0
[root@50:B3:42:00:00:A3 network-scripts]# cat /sys/class/net/bond1/bonding/mii
miimon mii_status
[root@50:B3:42:00:00:A3 network-scripts]# cat /sys/class/net/bond1/bonding/miimon
100
[root@50:B3:42:00:00:A3 network-scripts]# cat /proc/net/bonding/bond1

并且可以ping通bond接口，链路状态正常：
# ping 172.16.252.225
PING 172.16.252.225 (172.16.252.225) 56(84) bytes of data.
64 bytes from 172.16.252.225: icmp_seq=1 ttl=64 time=1.88 ms
64 bytes from 172.16.252.225: icmp_seq=2 ttl=64 time=0.122 ms

64 bytes from 172.16.252.225: icmp_seq=5 ttl=64 time=0.117 ms
然后使用IOmeter通过bonding接口对磁盘进行流量读写，查看数据流量的分布，bonding接口的模式是balance-rr，使用命令来分析数据流量：
sar -n DEV 2 100
但结果和想象的不一样：
# sar -n DEV 2 100

我们可以看到数据流不平衡，大部分数据流在eth6上，可能某些参数设置不正确，或者存在其他错误，你能帮助我吗？非常感谢！！！

我的机器连接到交换机的这4个端口。同时我将相应接口的link-port类型配置为使用权。
答案1
您没有显示交换机配置。通常，balance-rr 模式需要交换机上的 Etherchannel（Cisco）或 trunk 配置才能正常工作。您是否在交换机上建立了分组H3C S5800交换机？
看此处的注释。
The balance-rr, balance-xor and broadcast modes generally
require that the switch have the appropriate ports grouped together.
The nomenclature for such a group differs between switches, it may be
called an "etherchannel" (as in the Cisco example, above), a "trunk
group" or some other similar variation.
