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

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。
