我仍然是一个VLAN和集群的初学者，我正在努力使这个拓扑工作。具体来说，我无法从PC4 (10.0.10.10/32)中选择PC1 (10.0.10.10/32)，尽管它们都在VLAN 10上。

我相信我已经设置了适当的开关端口，包括模式访问和交换机1和3之间的中继端口，以及开关2和3。我没有在任何接口或VLAN上设置IP地址，因为我认为这是不必要的。

现在我将介绍每个开关的文本输出。其中每一个都结合了运行配置、显示vlan简要信息和显示接口主干命令。

如果能提供任何帮助，我将不胜感激。我可以根据需要生成任何附加信息。提前谢了。

编辑:按照罗恩·特伦克的建议，为每个交换机添加生成树VLAN 10命令的输出。开关3的输出看起来很短。

您还没有在交换机3上创建VLAN。

您必须先创建VLAN，然后才能将端口分配给它。
