实验目的：
l配置交换机的基本命令
实验说明：
Cisco的交换机配置命令和Router的配置命令基本一致, 故这里不做详细介绍
实验拓扑图：
实验步骤：
1. 了解基本配置

2. 简单验证
1) PC1 IP:192.168.30.23/24
PC2 IP:192.168.30.24/24
2) PC1 连结到Sw1的Fa0/1端口，PC2 连结到Sw1的Fa0/2端口，观察两个端口指示灯变成绿色的时间：
Fa0/1: ___s
Fa0/2: ___s
3） PC1 ping PC2：
C:\Documents and Settings\Joseph>ping 192.168.30.24 Pinging 192.168.30.24 with 32 bytes of data: Request timed out. Request timed out. Request timed out. Request timed out. Ping statistics for 192.168.30.24: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss), |
4） 将PC1 连结到Sw1的Fa0/3端口，PC1 再ping PC2：
