二、配置trunk并允许所有vlan通过

swh1、swh2、swh3三台交换机的g0/0/24链接的是swh4,swh4可以看作是是核心交换机,所以我们必须将123三台交换机的g0/0/24配置成trunk,并且要配置允许所有vlan通过

[swh1]int g0/0/24	
[swh1-GigabitEthernet0/0/24]port link-type trunk 
[swh1-GigabitEthernet0/0/24]port trunk allow-pass vlan all   ##允许所有vlan通过 
[swh1-GigabitEthernet0/0/24]q
[swh1]q
<swh1>save

[swh2]int g0/0/24	
[swh2-GigabitEthernet0/0/24]port link-type trunk
[swh2-GigabitEthernet0/0/24]port trunk allow-pass vlan all 
[swh2-GigabitEthernet0/0/24]q
[swh2]q
<swh2>save

[swh3]int g0/0/24	
[swh3-GigabitEthernet0/0/24]port link-type trunk
[swh3-GigabitEthernet0/0/24]port trunk allow-pass vlan all
[swh3-GigabitEthernet0/0/24]q
[swh3]q
<swh3>save

查看vlan

[swh1]dis vlan

三、核心交换机swh4的配置

我们从拓扑图上看出swh4是此网络的核心交换机,因此swh4上的配置尤为重要,步骤如下:

  • 首先必须将g0/0/1g0/0/2g0/0/3的端口类型更改为trunk
  • 其次必须将g0/0/1g0/0/2g0/0/3的端口配置为允许所有vlan通过;
  • 创建对应的vlan10、vlan20、vlan30,并且为这三个vlan配置IP地址。
