S交换机eth-trunk 链路聚合配置
此功能在S交换机中通用，如S2700,S3700,S5700,S6700,S7700,S9300,S9700
解决方案[SwitchA] interface Eth-Trunk1
[SwitchA-Eth-Trunk1] trunkport gigabitethernet 0/0/1 to 0/0/3
[SwitchA-Eth-Trunk1] quit
[SwitchA] interface Eth-Trunk1 //按需配置接口的vlan
[SwitchA-Eth-Trunk1] port link-type trunk
[SwitchA-Eth-Trunk1] port trunk allow-pass vlan 10 20
如果需要使用LACP的方式，添加mode lacp。如果是已添加接口，转换时需要先去除接口。
[SwitchA] interface eth-trunk 1
[SwitchA-Eth-Trunk1] mode lacp

华为S5700的手工链路聚合配置
1、建立 eth-trunk ID
2、将配置eth-trunl的link-type为trunk
3、设置允许通过的vlan
4、将端口加入eth-trunk
配置实例：
#
int eth-trunk 1
port link-type trunk
port trunk allow vlan 10 to 100
#
int g0/0/1
eth-trunk 1
#int g0/0/2
eth-trunk 1
#
return
验证命令：
dis trunkmembership 验证是否创建成功，端口是否加入
dis eth-trunk 1 查看eth-trunk 1的配置
==========================================================================================
interface Eth-Trunk 1 /创建聚合链路，数值可以随意。 port link-type trunk /设置成trunk模式。(如果是接入vlan的话，link-type acess) port trunk allow-pass vlan all /设置允许所有vlan.(接入vlan的话，port default vlan 20) mode manual load-balance /设置为手动负载 trunkport g0/0/10 to g0/0/13 /加入接口。
trunkport g0/0/10 to g0/0/14 /加入接口。
查看效果：
[txkj2]display eth-trunk 1
Eth-Trunk1's state information is:
WorkingMode: NORMAL Hash arithmetic: According to SIP-XOR-DIP
Least Active-linknumber: 1 Max Bandwidth-affected-linknumber: 8
Operate status: up Number Of Up Port In Trunk: 2
--------------------------------------------------------------------------------
PortName Status Weight
GigabitEthernet0/0/13 Up 1
GigabitEthernet0/0/14 Up 1
[txkj2]display trunkmembership eth-trunk 1
Trunk ID: 1
Used status: VALID
TYPE: ethernet
Working Mode : Normal
Number Of Ports in Trunk = 2
Number Of Up Ports in Trunk = 2
Operate status: up
Interface GigabitEthernet0/0/13, valid, operate up, weight=1
Interface GigabitEthernet0/0/14, valid, operate up, weight=1
华为端口聚合分为两种，手工负载分担eth-trunk链路和LACP eth-trunk链路，我这里只介绍前者。
