12、注意事项及其总结：
vlan，mstp，链路聚合：
1.创建VLAN+命名VLAN+把相应的接口加入VLAN
第一种方法：
vlan 10
name shichang
port g1/0/3
第二种方法：
vlan 20
name xiaoshou
quit
int g1/0/3
port link-type access
port access vlan 10
//配置在哪：在接入层交换机的连接PC的接口处，配置为access口并且加入相应的VLAN
2.配置trunk，并放通相应的vlan流量
int range g1/0/0 to g1/0/1
port link-type trunk
port trunk permit vlan 10 20 30 40
//配置在哪：
在接入层交换机的上行口处配置为trunk口，因为要通过多种VLAN，所以为trunk
在汇聚层交换机的下行口处配置为trunk口，交换机之间配置为trunk口
3.配置链路聚合
①创建聚合口
int bridge-aggregation 1
quit
②把物理口加入到相应的聚合组
int range g1/0/2 to g1/0/3
port link-aggregation group 1
quit
③在聚合口下配置trunk和放行相关VLAN
int bridge-aggregation 1
port link-type trunk
port trunk permit vlan 10 20 30 40
//配置在哪：汇聚层交换机处
配置链路聚合的注意事项：聚合成功的要求：聚合组中所有物理口的Vlan和接口配置必须一致；聚合口中的Vlan和接口配置必须和物理口的必须一致
//所以要严格按照顺序配置：1.创建聚合口
2.把物理口加入到聚合组
3.在聚合口下配置Trunk和Vlan相关
4.MSTP配置：
①进入MSTP的域配置
stp region-configuration //进入域配置
region-name H3C //配置域名
revision-level 1 //配置修订等级
instance 1 vlan 10 20 //配置实例1，绑定vlan10 20
instance 2 vlan 30 40 //配置实例2，绑定vlan30 40
active region-configuration //激活域配置
//配置在哪：配置在所有参与VLAN选举的交换机上，SW1、SW2、SW3
(必须配置一致)
②进行配置主备根桥
SW1：
stp instance 1 root primary
stp instance 2 root secondary
SW2:
stp instance 1 root secondary
stp instance 2 root primary
//实例1的主根桥配置在哪：在SW3上配置，对于vlan10 20他们的主根桥在SW3，那么bp就一定不在SW3所相对的接口，
只能在SW1和SW2相连的口上，那么就达到了VLAN10 20走不通SW2，VLAN10 20只能走SW3的效果
//实例2的主根桥配置在哪：在SW2上配置，对于VLAN30 40他们的主根桥在SW2，那么bp就一定不在SW2所相对的接
口，只能在SW1和SW3相连的口上，那么就达到了VLAN 30 40走不通SW3，VLAN30 40只能走通SW2的效果
5.边缘端口的配置：
int range g1/0/3 to g1/0/6
stp edge-port
stp bpdu-protection
//配置在哪：配置在接入层交换机的下行口，也就是接入PC的那个接口
//边缘接口：不参与生成树的计算
//bpdu保护：因为边缘端口，一旦收到真的BPDU（把PC断掉，连接一个交换机）或者假的BPDU（黑客恶意伪造的报
文）报文，就会立刻变为正常的端口，为了防止这个我们设置保护后，一旦收到，就会down掉
6、注意：
1.trunk 树干
2.bridge-aggregation 桥聚合
