思科：3560G
华为：S5300

思科G0/25---华为G0/0/1
思科G0/27---华为G0/0/2

华为交换机配置链路聚合有两种模式，分别是manual和lacp-static，如果不做配置，交换机默认是manual，所以一定要手动将模式改为lacp-static，这点很重要，否则无法跟思科交换机成功协商LACP。

华为交换机
#interface Eth-Trunk1
port link-type trunk
port trunk allow-pass vlan 2 to 4094
mode lacp-static //修改链路聚合模式
max active-linknumber 2 //设置最大活动链接数为2
bpdu enable //开启BPDU

#lacp priority 100

#interface GigabitEthernet0/0/1
eth-trunk 1
undo ntdp enable
undo ndp enable
（在配置端口前，一定要将端口原有配置清空，全部undo掉，否则无法应用eth-trunk命令。如果之前端口配置过trunk口，可以使用undo port link-type清除trunk状态）

#interface GigabitEthernet0/0/2
eth-trunk 1
undo ntdp enable
undo ndp enable

思科交换机
interface port-channel1
switchport trunk encapsulation dot1q
switchport mode trunk

interface g0/25
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode active

interface g0/27
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode active
