服务器是DELL R720,网卡是Broadcom Corporation NetXtreme BCM5720 Gigabit Ethernet PCIe,安装了64位的CentOS6.4系统。
我将服务器其中的em1,em3两块千兆网卡做bond,设置成mode=0时能够正常工作,达到负载均衡的效果。
现在我希望能够将两块1G网卡带宽扩大至2G。设置为mode=4,并且在交换机那一端也做了端口汇聚的设置。但用netperf测试时,发现流量只走其中一块网卡走,并且查看 /proc/net/bonding/bond0 文件内容如下:
Ethernet Channel Bonding Driver: v3.6.0 (September 26, 2009)
Bonding Mode: IEEE 802.3ad Dynamic link aggregation
Transmit Hash Policy: layer2 (0)
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0
802.3ad info
LACP rate: slow
Aggregator selection policy (ad_select): stable

Number of ports: 1 这里正常情况下应该是2吧。请问是什么原因导致我遇到的这个问题呢?
