无法ping PC到PC（通过交换机3550连接）

我猜这很简单，因为我最近才刚开始联网，而今天是我第二天忙于处理此交换机和虚拟机。我会提供所有我认为可能相关的信息-如果您需要更多信息，请提及。

在虚拟机上未启用防火墙。

PC和交换机的子网掩码是255.255.255.0

我使用的电缆是cat5e直通电缆。

设置：

虚拟PC 1. 192.168.2.10-电缆-cisco 3550交换机（192.168.2.1）-电缆-虚拟PC 2.192.168.2.11

问题：我无法从PC ping到PC。

我能做什么：

1. 从PC1 ping到交换机
2. 从PC2 ping到交换机
3. 从交换机Ping通到PC1
4. 从交换机Ping通到PC2

虚拟PC使用虚拟盒托管，并使用我添加到台式机PCIe插槽中的NIC。我正在使用Tera Term通过控制台电缆与交换机进行通信。

编辑：我忘了提到我从ping收到的错误是“目标主机不可达”。

此后将发布其他必需的信息

显示ip interface brief从此（我忘了提一下）可以很明显地看出PC1和PC2的活动端口分别是fa0 / 7和fa0 / 8。
