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

<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
g0/0/1、g0/0/2、g0/0/3的端口类型更改为trunk； - 其次必须将
g0/0/1、g0/0/2、g0/0/3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。
