4、中小企业网络架构-汇聚层交换机基本配置

网络拓扑：

配置思路：

添加vlan；配置下联接口；配置上联双链路接口

操作步骤：

一、SW3汇聚交换机

1、添加vlan

system-view 
[Huawei]sysname SW3
[SW3]vlan batch 2 10

2、配置下联接口

[SW3]interface  GigabitEthernet 0/0/1
[SW3-GigabitEthernet0/0/1]port link-type trunk	
[SW3-GigabitEthernet0/0/1]port trunk  allow-pass  vlan  all
[SW3-GigabitEthernet0/0/1]description connect to SW5
[SW3-GigabitEthernet0/0/1]quit

3、配置上联双链路接口

[SW3]interface  GigabitEthernet 0/0/2
[SW3-GigabitEthernet0/0/2]port link-type trunk	
[SW3-GigabitEthernet0/0/2]port trunk allow-pass vlan all
[SW3-GigabitEthernet0/0/2]description connect to SW1
[SW3-GigabitEthernet0/0/2]quit

[SW3]interface  GigabitEthernet  0/0/3
[SW3-GigabitEthernet0/0/3]port link-type trunk
[SW3-GigabitEthernet0/0/3]port trunk allow-pass  vlan  all
[SW3-GigabitEthernet0/0/3]description connect to SW2
[SW3-GigabitEthernet0/0/3]quit

二、SW4汇聚交换机

1、添加vlan

system-view
[Huawei]sysname SW4
[SW4]vlan batch 3 9

2、配置下联接口

[SW4]interface  GigabitEthernet  0/0/1
[SW4-GigabitEthernet0/0/1]port link-type trunk
[SW4-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[SW4-GigabitEthernet0/0/1]description connect to SW6
[SW4-GigabitEthernet0/0/1]quit 

3、配置上联双链路接口

[SW4]interface  GigabitEthernet  0/0/2
[SW4-GigabitEthernet0/0/2]port link-type trunk
[SW4-GigabitEthernet0/0/2]port trunk  allow-pass vlan all
[SW4-GigabitEthernet0/0/2]description connect to SW2
[SW4-GigabitEthernet0/0/2]quit

[SW4]interface GigabitEthernet  0/0/3
[SW4-GigabitEthernet0/0/3]port link-type trunk
[SW4-GigabitEthernet0/0/3]port trunk  allow-pass  vlan  all
[SW4-GigabitEthernet0/0/3]description  connect to SW1	
[SW4-GigabitEthernet0/0/3]quit
