IB卡开启EIPOIB做虚拟化桥接使用

步骤1：开启EiPOIB

编辑默认"no"为"yes"

/etc/infiniband/openib.conf

E_IPOIB_LOAD=yes

步骤2：重启hca卡驱动。

/etc/init.d/openibd restart

重启后会生成以太网卡，可用ethtool exxx确认网卡速率。

如果服务重启失败，就重启os咯。

步骤3：查看eipoib以太网口和ib网口对应关系

[root@cs60 src]# cat /sys/class/net/eth_ipoib_interfaces

ens865 over IB port: ib0

ens865d1 over IB port: ib1

ens801 over IB port: ib2

ens801d1 over IB port: ib3

[root@cs60 src]#

步骤4：查看eipoib以太网卡mac地址

[root@cs60 eth]# cat /sys/class/net/ens865/eth/vifs

SLAVE=ib0.1 MAC=00:02:c9:44:8a:81 VLAN=N/A

SLAVE=ib0.2 MAC=00:02:c9:36:3f:71 VLAN=N/A

[root@cs60 eth]# cat /sys/class/net/ens865d1/eth/vifs

SLAVE=ib1.1 MAC=00:02:c9:44:8a:82 VLAN=N/A

[root@cs60 eth]# cat /sys/class/net/ens801/eth/vifs

SLAVE=ib2.1 MAC=00:02:c9:36:3f:71 VLAN=N/A

SLAVE=ib2.2 MAC=00:02:c9:44:8a:81 VLAN=N/A

[root@cs60 eth]# cat /sys/class/net/ens801d1/eth/vifs

SLAVE=ib3.1 MAC=00:02:c9:36:3f:72 VLAN=N/A

[root@cs60 eth]#

步骤5: 用eipoib以太网卡做虚拟化桥接用

[root@cs60 network-scripts]# cat ifcfg-ens801

BOOTPROTO=none

ONBOOT=yes

BOOTPROTO=none

BRIDGE=br0

MACADDR=00:02:c9:44:8a:81

[root@cs60 network-scripts]# cat ifcfg-br0
