（一）linux配置#cat /boot/config-kernel-version |grep -i bondingCONFIG_BONDING=m返回CONFIG_BONDING=m表示支持，否则需要编译内核使它支持bonding也可以用：查看一下内核是否已经支持bonding：modinfo bonding第一步：创建一个ifcfg-bondX# touch /etc/sysconfig/network-scripts/ifcfg-bond0 新建一个bond0配置文件# cat /etc/sysconfig/network-scripts/ifcfg-bond0DEVICE=bond0BOOTPROTO=staticIPADDR=1.1.1.2NETMASK=255.255.255.0BROADCAST=1.1.1.255NETWORK=1.1.1.0GATEWAY=1.1.1.1ONBOOT=yesTYPE=Ethernet编辑ifcfg-bond0如上第二步：修改/etc/sysconfig/network-scripts/ifcfg-ethX这个实验中把网卡1和2绑定，修改/etc/sysconfig/network-scripts/ifcfg-ethX相应网卡配置如下：# cat /etc/sysconfig/network-scripts/ifcfg-eth1TYPE=EthernetDEVICE=eth1HWADDR=00:d0:f8:40:f1:a0 网卡1macBOOTPROTO=noneONBOOT=yesUSERCTL=noMASTER=bond0SLAVE=yes# cat /etc/sysconfig/network-scripts/ifcfg-eth2TYPE=EthernetDEVICE=eth2HWADDR=00:d0:f8:00:0c:0c 网卡2macBOOTPROTO=noneONBOOT=yesUSERCTL=noMASTER=bond0SLAVE=yes第三步：配置/etc/modprobe.conf，添加alias bond0 bonding# cat /etc/modprobe.confalias eth0 e100alias snd-card-0 snd-intel8x0options snd-card-0 index=0options snd-intel8x0 index=0remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0alias eth1 8139toooptions 3c501 irq=3alias eth2 tulip上面是三网卡本身的配置如果要绑定和做lacp只要再加上下面两条配置alias bond0 bonding 绑定options bond0 miimon=100 mode=4 mode=4是lacp第四步：配置/etc/rc.d/rc.local，添加需要绑定的网卡# cat /etc/rc.d/rc.localtouch /var/lock/subsys/local 配置本身就有这条命令ifenslave bond0 eth1 eth2 这条命令是添加需要绑定的网卡1和2到这里就完成bonding的配置了可以查看一下第五步：重启网络服务和重启pc#service network restart 重启网络服务# shutdown -r now 重启pc重启后可以查看bonding情况：网卡1和2 都绑定上了，模式为802.3ad# cat /proc/net/bonding/bond0Ethernet Channel Bonding Driver: v3.0.3 (March 23, 2006)Bonding Mode: IEEE 802.3ad Dynamic link aggregationTransmit Hash Policy: layer2 (0)MII Status: upMII Polling Interval (ms): 100Up Delay (ms): 0Down Delay (ms): 0802.3ad infoLACP rate: slowActive Aggregator Info:Aggregator ID: 1Number of ports: 2Actor Key: 9Partner Key: 1Partner Mac Address: 00:d0:f8:22:33:baSlave Interface: eth1MII Status: upLink Failure Count: 0Permanent HW addr: 00:d0:f8:40:f1:a0Aggregator ID: 1Slave Interface: eth2MII Status: upLink Failure Count: 0Permanent HW addr: 00:d0:f8:00:0c:0cAggregator ID: 1接口配置信息:新增了bond0的配置信息，接口bond0和eth1，eth2，绑定后三个接口使用的mac都是同一个：00:D0:F8:40:F1:A0# ifconfigbond0 Link encap:Ethernet HWaddr 00:D0:F8:40:F1:A0inet addr:1.1.1.2 Bcast:1.1.1.255 Mask:255.255.255.0inet6 addr: fe80::2d0:f8ff:fe40:f1a0/64 Scope:LinkUP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1RX packets:128 errors:0 dropped:0 overruns:0 frame:0TX packets:259 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:0RX bytes:15466 (15.1 KiB) TX bytes:39679 (38.7 KiB)eth0 Link encap:Ethernet HWaddr 00:11:11:EB:71:E2inet addr:192.168.180.8 Bcast:192.168.180.15 Mask:255.255.255.240inet6 addr: fe80::211:11ff:feeb:71e2/64 Scope:LinkUP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1RX packets:311 errors:0 dropped:0 overruns:0 frame:0TX packets:228 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:1000RX bytes:30565 (29.8 KiB) TX bytes:35958 (35.1 KiB)eth1 Link encap:Ethernet HWaddr 00:D0:F8:40:F1:A0inet6 addr: fe80::2d0:f8ff:fe40:f1a0/64 Scope:LinkUP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1RX packets:54 errors:0 dropped:0 overruns:0 frame:0TX packets:97 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:1000RX bytes:6696 (6.5 KiB) TX bytes:13821 (13.4 KiB)Interrupt:209 Base address:0x2e00eth2 Link encap:Ethernet HWaddr 00:D0:F8:40:F1:A0inet6 addr: fe80::2d0:f8ff:fe40:f1a0/64 Scope:LinkUP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1RX packets:74 errors:0 dropped:0 overruns:0 frame:0TX packets:162 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:1000RX bytes:8770 (8.5 KiB) TX bytes:25858 (25.2 KiB)Interrupt:201 Base address:0x2f00lo Link encap:Local Loopbackinet addr:127.0.0.1 Mask:255.0.0.0inet6 addr: ::1/128 Scope:HostUP LOOPBACK RUNNING MTU:16436 Metric:1RX packets:6283 errors:0 dropped:0 overruns:0 frame:0TX packets:6283 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:0RX bytes:9783674 (9.3 MiB) TX bytes:9783674 (9.3 MiB)（二）锐捷交换机配置：lacp system-priority 100 全局配置lacp优先级interface GigabitEthernet 0/23no switchportlacp port-priority 100 接口的lacp优先级port-group 1 mode active 接口下开启lacp 主动模式interface GigabitEthernet 0/24no switchportlacp port-priority 100port-group 1 mode activeinterface AggregatePort 1no switchportno ip proxy-arpip address 1.1.1.1 255.255.255.0和linux成功建立lacp后状态信息如下：Show lacp summarySystem Id:100, 00d0.f822.33baFlags: S - Device is requesting Slow LACPDUs F - Device is requesting Fast LACPDUs.A - Device is in active mode.
