華為交換機鏈路聚合：
方式一：配置手工負載分擔方式的鏈路聚合
[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模式的鏈路聚合
[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上配置系統(tǒng)優(yōu)先級為100，使其成為LACP主動端[CORE1] lacp priority 100
# 在CORE1上配置活動接口上限閾值為2[CORE1] interface Eth-Trunk 1
[CORE1-Eth-Trunk1] max active-linknumber 2
[CORE1-Eth-Trunk1] quit
# 在CORE1上配置接口優(yōu)先級確定活動鏈路（配置GE0/0/5和GE0/0/6為活動鏈路）[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鏈路聚合bond
1、mode=0(balance-rr)(平衡掄循環(huán)策略)2、mode=1(active-backup)(主-備份策略)3、mode=2(balance-xor)(平衡策略,根據(jù)hash策略平衡)4、mode=3(broadcast)(廣播策略，高可靠較浪費資源)5、mode=4(802.3ad)(IEEE 802.3ad 動態(tài)鏈接聚合)6、mode=5(balance-tlb)(適配器傳輸負載均衡)7、mode=6(balance-alb)(適配器適應性負載均衡)
