一台h3c s7510E下面连着一台华为s5700交换机，要做链路聚合，经过测试完成配置：
华为交换机配置：
interface Eth-Trunk2 #创建聚合接口，注意要使用默认的manual模式
port link-type trunk #设置接口为trunk模式
port trunk allow-pass vlan 10 #配置允许通过的vlan ID
interface GigabitEthernet0/0/47 #进入要做聚合的接口
undo negotiation auto #取消端口自动配置
eth-trunk 2 #加入聚合接口
#
interface GigabitEthernet0/0/48
undo negotiation auto
eth-trunk 2
h3c交换机配置：
[Quidway] interface Bridge-Aggregation 1 #创建聚合接口，要使用默认的静态模式
port link-type trunk
port trunk permit vlan 1 100 600 610
[Quidway] interface GigabitEthernet1/0/11 #进入要聚合的端口
port link-mode bridge # port bridge enable
port link-aggregation group 1 #将端口加入聚合接口
[Quidway] interface GigabitEthernet1/0/12
port link-mode bridge # port bridge enable
port link-aggregation group 1
HWS5700 配置完成后查看聚合状态：

总结：配置期间走了不少弯路，最后发现不同交换机直接配置链路聚合只能都使用手动模式（静态模式）
的lacp，这样就容易成功。
因为是自己亲身体验过的。
H3C：默认是静态模式，下面是配成动态lacp命令
[switch-A-Bridge-Aggregation1]link-aggregation mode dynamic
HW关闭自动协商的命令
[Quidway-GigabitEthernet0/0/1]undo negotiated auto

少部分按照自己配置的过程做了一些调整了修改。
下面简单介绍下H3C静态lacp和动态lacp
H3C配置静态LACP汇聚组
进入系统视图 system-view
创建汇聚组 link-aggregation group agg-id mode static
进入以太网端口视图 interface interface-type interface-number
将以太网端口加入汇聚组 port link-aggregation group agg-id
动态lacp：
进入系统视图 system-view
配置系统优先级 lacp system-priority system-priority可选 缺省情况下，系统优先级为32768
进入以太网端口视图 interface interface-type interface-number
开启端口LACP协议 lacp enable 缺省情况下，端口的LACP协议处于关闭状态
配置端口优先级 lacp port-priority port-priority 缺省情况下，端口优先级为32768
