本期为大家带来华三交换机的链路聚合的实例，请看拓补图

前言：华三的交换机链路聚合和华为的有异曲同工之妙，下面是关键字

华三Bridge-Aggregation1  =华为Eth-trunk

华三加入聚合组，在端口下敲 port link-aggregation group 1 华为则是：Eth-trunk1

华三选择动态聚合模式link-aggregation mode dynamic 华为则是，mode XX？

本次案例拓补图如下

整体思路和华为一样，创建聚合组，选择聚合模式，将端口加入聚合组，聚合组端口透传vlan，本次实验案例我在核心交换机创建地址池，然后让PC去获取，以此证明聚合端口没有问题

值得注意的是，在无环网络中我们是不需要开启STP的，有环网络中需要开启STP

接入交换机ACCESS：接入PC的交换机

配置如下：

CORE：

#
 dhcp enable
#
vlan 10
#
 stp global enable
#
dhcp server ip-pool vlan10 //创建一个名为“vlan10”的地址池
 gateway-list 192.168.10.254 //设置地址池网关
 network 192.168.10.0 mask 255.255.255.0 //宣告地址池的工作网络网段
 expired unlimited //地址租期为永久
#
interface Bridge-Aggregation1 //进入聚合组端口1
 port link-type trunk
 undo port trunk permit vlan 1
 port trunk permit vlan 10
 link-aggregation mode dynamic  //修改聚合端口的模式为，动态聚合
#
interface Vlan-interface10
 ip address 192.168.10.254 255.255.255.0
#
interface GigabitEthernet1/0/1
 port link-mode bridge //代表这是一个二层接口
 port link-type trunk
 undo port trunk permit vlan 1
 port trunk permit vlan 10
 combo enable fiber
 port link-aggregation group 1 //加入聚合组1
#
interface GigabitEthernet1/0/2
 port link-mode bridge 
 port link-type trunk
 undo port trunk permit vlan 1
 port trunk permit vlan 10
 combo enable fiber
 port link-aggregation group 1 //加入聚合组1
#

接入交换机ACCESS配置：

#
vlan 10
#
interface Bridge-Aggregation1
 port link-type trunk
 undo port trunk permit vlan 1
 port trunk permit vlan 10
 link-aggregation mode dynamic
#
interface GigabitEthernet1/0/1
 port link-mode bridge
 port link-type trunk
 undo port trunk permit vlan 1
 port trunk permit vlan 10
 combo enable fiber
 port link-aggregation group 1
#
interface GigabitEthernet1/0/2
 port link-mode bridge
 port link-type trunk
 undo port trunk permit vlan 1
 port trunk permit vlan 10
 combo enable fiber
 port link-aggregation group 1
#
interface GigabitEthernet1/0/3
 port link-mode bridge
 port access vlan 10
 combo enable fiber
#
interface GigabitEthernet1/0/4
 port link-mode bridge
 port access vlan 10
 combo enable fiber
