实验过程: 第一步:登录sw1 S1#show vlan-s

VLAN Name Status Ports


1 default active Fa0/0, Fa0/1, Fa0/2, Fa0/3 Fa0/4, Fa0/5, Fa0/6, Fa0/7 Fa0/8, Fa0/9, Fa0/10, Fa0/11 Fa0/12, Fa0/13, Fa0/14, Fa0/15 1002 fddi-default active
1003 token-ring-default active
1004 fddinet-default active
1005 trnet-default active

1005 trnet 101005 1500 - - 1 ibm - 0 0
S1# 第二步:进入vlan database模式下 S1#vlan da S1#vlan database (进入数据库模式下进行) S1(vlan)#vlan 2 name VLAN2 VLAN 2 added: Name: VLAN2 S1(vlan)#vlan 3 name vlan3 VLAN 3 added: Name: vlan3 S1(vlan)#vlan 4 name vlan4 VLAN 4 added: Name: vlan4 S1(vlan)#exit APPLY completed. Exiting.... S1#

第三步:再次查看创建vlan的结果: S1#show vlan-switch

S1# 第四步:查看vlan配置文件 S1#dir flash: (vlan的信息在2900系列上是保存在flash下的vlan.dat文件中的) Directory of flash:/

1  -rw-         780                    <no date>  vlan.dat

8388604 bytes total (8387760 bytes free) S1# 第五步:将F0/2划入到vlan中 S1(config)#int f0/2 S1(config-if)#switchport mode access S1(config-if)#switchport access vlan 2 S1(config-if)# S1(config-if)# 第六步:验证是否将接口划分到vlan中 S1#show vlan-s

清除交换机上划分的大量的vlan信息 1.vlan data下no vlan {vlan-id} 2.del vlan.dat
