VLAN
vlan
1.在全局配置模式下创建虚拟局域网
Switch#configure terminal
Switch(config)#vlan 2 创建vlan2
Switch(config-vlan)#name ff 给vlan2命名
Switch(config-vlan)#vlan 3
Switch(config-vlan)#name jj
Switch(config)#interface f0/1 分别将f0/1,f0/2加入到vlan2中
Switch(config-if)#switchport access vlan 2
Switch(config-if)#exit
Switch(config)#interface f0/2
Switch(config-if)#switchport access vlan 2
Switch(config)#interface range f0/3-4 一次性将f0/3,f0/4加入到vlan3中
Switch(config-if-range)#switchport access vlan 3
Switch#show vlan
VLAN Name Status Ports
---- -------------------------------- --------- -------------------------------
1 default active Fa0/5, Fa0/6, Fa0/7, Fa0/8
Fa0/9, Fa0/10, Fa0/11, Fa0/12
Fa0/13, Fa0/14, Fa0/15, Fa0/16
Fa0/17, Fa0/18, Fa0/19, Fa0/20
Fa0/21, Fa0/22, Fa0/23, Fa0/24
2 ff active Fa0/1, Fa0/2
3 jj active Fa0/3, Fa0/4
测试连通性，得出实验结果
2.在特权模式下创建虚拟局域网
Switch>enable
Switch#vlan database 进入虚拟局域网数据库
Switch(vlan)#vlan 2 name ff 在库中创建vlan2,3
Switch(vlan)#vlan 3 name jj
Switch#show vlan
VLAN Name Status Ports
---- -------------------------------- --------- -------------------------------
1 default active 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, Fa0/16
Fa0/17, Fa0/18, Fa0/19, Fa0/20
Fa0/21, Fa0/22, Fa0/23, Fa0/24
2 ff active
3 jj active
Switch#conf t
Switch(config)#interface range f0/1-2 一次性将f0/1,f0/2加入到vlan2中
Switch(config-if-range)#switchport access vlan 2
Switch(config-if-range)#exit
Switch(config)#interface range f0/3-4 一次性将f0/3,f0/4加入到vlan3中
Switch(config-if-range)#switchport access vlan 3
3.从虚拟局域网中删除某个接口
Switch(config)#int f0/1
Switch(config-if)#no switchport access vlan 2
Switch(config-if)#end
Switch#show vlan
VLAN Name Status Ports
---- -------------------------------- --------- -------------------------------
1 default active Fa0/1, Fa0/5, Fa0/6, Fa0/7
Fa0/8, Fa0/9, Fa0/10, Fa0/11
Fa0/12, Fa0/13, Fa0/14, Fa0/15
Fa0/16, Fa0/17, Fa0/18, Fa0/19
Fa0/20, Fa0/21, Fa0/22, Fa0/23
Fa0/24
2 ff active Fa0/2
3 jj active Fa0/3, Fa0/4
4.删除空vlan
Switch(config)#no vlan 3
如果虚拟局域网中有接口，是不能直接删除当前的vlan的。
5.将多个接口同时加入一个虚拟局域网中
Switch(config)#interface range f0/5-7,f0/9,f0/11-15
Switch(config-if-range)#switchport access vlan 2
Switch#show vlan
VLAN Name Status Ports

1 default active Fa0/1, Fa0/8, Fa0/10, Fa0/16
Fa0/17, Fa0/18, Fa0/19, Fa0/20
Fa0/21, Fa0/22, Fa0/23, Fa0/24
2 ff active Fa0/2, Fa0/5, Fa0/6, Fa0/7
Fa0/9, Fa0/11, Fa0/12, Fa0/13
Fa0/14, Fa0/15
