单个交换机的VLAN的划分

关于单个交换机的VLAN的搭建 一: 实现的目标 1. 了解VLAN的含义及用途。   VLAN是覆盖面积相对狭小的几台计算机和设备相连的的网络。    VLAN 可以隔离广播域，实现部分网络的安全。如:销售部和财务部之间划分VLAN可以实现销售部不能直接访问财务部的内部网络，从而实现两个部门的安全性。    VLAN 方便管理，有利于以后网络拓扑的变化。 2. VLAN的配置 3. VLAN的管理 4. VLAN的应用   二．单个交换机划分VLAN拓扑结构 三．实验过程   1.使用平行线连接交换机和pc。   2. 配置pc的ip地址 PC                 IP       接口 Pc0            192.168.1.2    fa0/1 Pc1            192.168.1.3    fa0/2 Pc2            192.168.1.4    fa0/3 Pc3            192.168.1.5    fa0/4 Pc4            192.168.1.6    fa0/5 Pc5            192.168.1.7    fa0/6 Pc6            192.168.1.8    fa0/7  3.在交换机上配置VLAN     1．建立VLAN    Switch # vlan database    Switch#vlan 2 name xiaoshuo    Switch#vlan 3 name gongguan    Switch#vlan 4 name caiwu    Switch#end   2.pc加入vlan Switch#conf t Switch#int fa0/1 Switch#switchport access vlan 2 Switch#int fa0/2 Switch #switchport access vlan2 Switch#end Switch#conf t Switch#int fa0/3 Switch #switchport access vlan3 Switch#end Switch#conf t Switch#int fa0/4 Switch #switchport access vlan3 Switch#end Switch#conf t Switch#int fa0/5 Switch #switchport access vlan4 Switch#end Switch#conf t Switch#int fa0/6 Switch #switchport access vlan4 Switch#end Switch#conf t Switch#int fa0/7 Switch #switchport access vlan4 Switch#end  3.检测pc0和pc2之间的ping是否通信   Vlan2与vlan2之间能否通信     Pinging 192.168.1.3 with 32 bytes of data:   Reply from 192.168.1.3: bytes=32 time=90ms TTL=128 Reply from 192.168.1.3: bytes=32 time=40ms TTL=128 Reply from 192.168.1.3: bytes=32 time=30ms TTL=128 Reply from 192.168.1.3: bytes=32 time=40ms TTL=128   Ping statistics for 192.168.1.3:     Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds:     Minimum = 30ms, Maximum = 90ms, Average = 50ms , Vlan2与vlan3之间能否通信   PC>ping 192.168.1.4   Pinging 192.168.1.4 with 32 bytes of data:   Request timed out. Request timed out. Request timed out. Request timed out.   Ping statistics for 192.168.1.4:     Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),   Vlan2与vlan4之间能否通信 PC>ping 192.168.1.6   Pinging 192.168.1.6 with 32 bytes of data:  
Request timed out. Request timed out. Request timed out. Request timed out.   Ping statistics for 192.168.1.6:     Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),   PC> 四．总结   1.VLAN可以隔离广播域，保证子网内部的安全。   2.vlan 可以划分与站点的位置无关，它可以是相当性质的站点的集合。   3.方便日后的管理。
