环境：Red Hat Enterprise Linux Server release 5.5 (Tikanga)
交换机：cisco 2960G

两台linux服务器上都有4个网口，并且全部链接到cisco 2960G，没有做vlan（应该是整个交换机是一个vlan1）。在linux端四个网口做了绑定mode=0；
这个是bonding状态

在交换机上做端口聚合（所有端口都是全双工，1000Mb）：
Switch(config)#int range Gi0/1 - 4
Switch(config-if-range)#switchport mode access
Switch(config-if-range)#channel-group 1 mode desirable non-silent
Switch(config-if-range)#exit

Switch(config)# port-channel load-balance src-dst-ip

实际结果：
从一台机器往另一台上同步数据，带宽只能达到1000mb/s;就是说收发的带宽都只能达到千兆，不能提升。请问这是什么问题？求解决办法？
