H3C對接華為S5700s---配置鏈路聚合
一臺h3c s7510E下面連著一臺華為s5700交換機，要做鏈路聚合，經過測試完成配置：
華為交換機配置：
interface Eth-Trunk2 #創建聚合接口，註意要使用默認的manual模式
port link-type trunk #設置接口為trunk模式
port trunk allow-pass vlan 10 #配置允許通過的vlan ID
interface GigabitEthernet0/0/47 #進入要做聚合的接口
undo negotiation auto #取消端口自動配置
eth-trunk 2 #加入聚合接口
#
interface GigabitEthernet0/0/48
undo negotiation auto
eth-trunk 2
h3c交換機配置：
[Quidway] interface Bridge-Aggregation 1 #創建聚合接口，要使用默認的靜態模式
port link-type trunk
port trunk permit vlan 1 100 600 610
[Quidway] interface GigabitEthernet1/0/11 #進入要聚合的端口
port link-mode bridge # port bridge enable
port link-aggregation group 1 #將端口加入聚合接口
[Quidway] interface GigabitEthernet1/0/12
port link-mode bridge # port bridge enable
port link-aggregation group 1
HWS5700 配置完成後查看聚合狀態：

總結：配置期間走了不少彎路，最後發現不同交換機直接配置鏈路聚合只能都使用手動模式（靜態模式）
的lacp，這樣就容易成功。
因為是自己親身體驗過的。
H3C：默認是靜態模式，下面是配成動態lacp命令
[switch-A-Bridge-Aggregation1]link-aggregation mode dynamic
HW關閉自動協商的命令
[Quidway-GigabitEthernet0/0/1]undo negotiated auto

少部分按照自己配置的過程做了一些調整了修改。
下面簡單介紹下H3C靜態lacp和動態lacp
H3C配置靜態LACP匯聚組
進入系統視圖 system-view
創建匯聚組 link-aggregation group agg-id mode static
進入以太網端口視圖 interface interface-type interface-number
將以太網端口加入匯聚組 port link-aggregation group agg-id
動態lacp：
進入系統視圖 system-view
配置系統優先級 lacp system-priority system-priority可選 缺省情況下，系統優先級為32768
進入以太網端口視圖 interface interface-type interface-number
開啟端口LACP協議 lacp enable 缺省情況下，端口的LACP協議處於關閉狀態
配置端口優先級 lacp port-priority port-priority 缺省情況下，端口優先級為32768
