配置trunk

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

swh4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。 <Huawei>sys Enter system view, return user view with Ctrl+Z.
