第一步：登录sw1
S1#show vlan-s

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....

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

3 vlan3 active
4 vlan4 active

1004 fdnet 101004 1500 - - 1 ibm - 0 0
1005 trnet 101005 1500 - - 1 ibm - 0 0
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.dat8388604 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
VLAN Name Status Ports
1 default active Fa0/0, Fa0/1, 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
2 VLAN2 active Fa0/2 （看到这里已经好了）
3 vlan3 active
4 vlan4 active
1002 fddi-default active
1003 token-ring-default active
1004 fddinet-default active
1005 trnet-default active

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
