实验名称:配置交换机上的VLAN
实验内容
使用Boson NetSim软件模拟出两台交换机的环境,并配置VLAN。
使用Boson NetSim Designer软件设计一个含有两个交换机、一个PC机和一个路由器的网络环境,如图所示:
网络为192.168.0.0/24。
在两台1900系列交换机上配置VLAN Router1:192.168.0.1。
PC1:192.168.0.2。
将Router1连接到交换机Switch1上的端口以及PC1连接到交换机Switch2上的端口设置到VLAN2(#后为注释,下同):
#conf t此时PC1无法ping通Router1,因为两台交换机没有联合子网信息。然后在两台交换机直接相连的端口上设置Trunk:
Enter configuration commands, one per line. End with CNTL/Z.
(config)#vlan 2 name vlan2
(config)#interface e0/1
(config-if)#vlan-membership static 2
(config-if)#exit
(config)#exit
#show vlan

在两台2950系列交换机上配置VLAN
将Router1连接到交换机Switch1上的端口以及PC1连接到交换机Switch2上的端口设置到VLAN2:Switch#vlan database
