实验一：跨交换机实现VLAN
一、实验环境：Windows7操作系统的计算机；
Boson Netsim for CCNA v6.0
二、实验步骤;
pc1接到sw1的PA0/1,pc2接到sw1的PA0/2,pc3接到sw2的PA0/1,pc4接到sw2的PA0/2；sw1的PA0/12接到sw2的PA0/12作为主干道，配置如下：
(1) switch1的配置
Switch>enable
Switch#config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#hostname switch1
switch1(config)#vlan 10
VLAN 10 added:
Name:VLAN0010
switch1(config)#interface fa 0/1
switch1(config-if)#switchport access vlan 10
switch1(config-if)#exit
switch1(config)#vlan 20
VLAN 20 added:
Name:VLAN0020
switch1(config)#inter fa 0/2
switch1(config-if)#switchport access vlan 20
switch1(config-if)#exit
switch1(config)#interface fa 0/12
switch1config-if)#switchport mode trunk
switch1(config-if)#end
(2) switch2的配置
Switch>enable
Switch#conf term
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#hostname switch2
switch2config)#vlan 10
VLAN 10 added:
Name:VLAN0010
switch2(config)#interface fa 0/1
switch2config-if)#switchport access vlan 10
switch2(config-if)#exit
switch2(config)#vlan 20
VLAN 20 added:
Name:VLAN0020
switch2(config)#interface fa 0/2
switch2(config-if)#switchport access vlan 20
switch2(config-if)#exit
switch2(config)#interface fa 0/12
switch2(config-if)#switch mode trunk
switch2(config-if)#end
(3) 配置PC机的IP地址与网关
C:>win
PC1：192.168.100.1 255.255.255.0 GATEWAY 192.168.1.1
PC2：192.168.100.2 255.255.255.0 GATEWAY 192.168.1.1
PC3：192.168.100.3 255.255.255.0 GATEWAY 192.168.1.1
PC4：192.168.100.4 255.255.255.0 GATEWAY 192.168.1.1

六、心得体会：
通过本次实验，掌握了交换机的配置过程，并顺利完成了跨交换机实现vlan的目标，但在实验过程中还是对命令不熟悉，有时会出错，今后要加强这方面的训练。
