华为交换机链路聚合：

方式一：配置手工负载分担方式的链路聚合
[CORE1] interface Eth-Trunk 1
[CORE1-Eth-Trunk1] trunkport GigabitEthernet 0/0/5 to 0/0/6
[CORE1-Eth-Trunk1] port link-type access
[CORE1-Eth-Trunk1] port default vlan 300
[CORE1-Eth-Trunk1] quit
方式二：配置LACP模式的链路聚合
[CORE1] interface Eth-Trunk 1
[CORE1-Eth-Trunk1] mode lacp
[CORE1-Eth-Trunk1] trunkport GigabitEthernet 0/0/5 to 0/0/6
[CORE1-Eth-Trunk1] port link-type access
[CORE1-Eth-Trunk1] port default vlan 300
[CORE1-Eth-Trunk1] quit
# 在CORE1上配置系统优先级为100，使其成为LACP主动端[CORE1] lacp priority 100
# 在CORE1上配置活动接口上限阈值为2[CORE1] interface Eth-Trunk 1
[CORE1-Eth-Trunk1] max active-linknumber 2
[CORE1-Eth-Trunk1] quit
# 在CORE1上配置接口优先级确定活动链路（配置GE0/0/5和GE0/0/6为活动链路）[CORE1] interface GigabitEthernet 0/0/5
[CORE1-GigabitEthernet0/0/5] lacp priority 100
[CORE1-GigabitEthernet0/0/5] quit
[CORE1] interface GigabitEthernet 0/0/6
[CORE1-GigabitEthernet0/0/6] lacp priority 100
[CORE1-GigabitEthernet0/0/6] quit

Linux链路聚合bond

1、mode=0(balance-rr)(平衡抡循环策略)2、mode=1(active-backup)(主-备份策略)3、mode=2(balance-xor)(平衡策略,根据hash策略平衡)4、mode=3(broadcast)(广播策略，高可靠较浪费资源)5、mode=4(802.3ad)(IEEE 802.3ad 动态链接聚合)6、mode=5(balance-tlb)(适配器传输负载均衡)7、mode=6(balance-alb)(适配器适应性负载均衡)
