新手求助：同一台交换机能配置有些vlan不互通有些vlan互通吗？

pc2 在vlan2   192.168.2.1  24    port link-type access   port default vlan 2
pc3 在vlan3   192.168.3.1  24    port link-type access   port default vlan 3
pc4 在vlan4   192.168.4.1  24    port link-type trunk     port trunk pvid vlan 4    port trunk allow-pass vlan 2 4
pc5 在vlan2   192.168.2.1  24    port link-type trunk     port trunk pvid vlan 2    port trunk allow-pass vlan 2 4
dhcp打开，各vlan自动获取ip

三个端口模式都试过都是互通的，搞不明白了

求高手配置下，谢谢了！

不通vlan隔离广播域，不同网段需要三层路由找网关

你虽然配置了VLAN，但是也启用了vlanif,创建了dhcp服务，vlan只能隔离二层，现在你的终端是三层通信的。如4.5去访问2.5，是4.5下一条为4.1，4.1是交换机 下一跳指向127.0.0.1   127.0.0.1指向2.1  2.1指向2.5

搞不明白。。。。
