21交换机802.1q vlan 的配置方法.锐捷网络远程技术支持中心技术热线：4008-111-000配置VLAN创建、修改一个VLAN步骤如下：song#configure terminal！进入全局模式Enter configuration commands, one per line. End with CNTL/Z.song(config)#vlan 2! 输入一个vlan id，如果输入的是一个新的vlan id，则交换机会创建一个vlan，如果输入的是已经存在的vlan id，则修改相应的vlan。在此是创建一个vlan号为2的。并进入vlan 2修改2006-03-14 10:13:53 5-CONFIG:Configured from outbandsong(config-vlan)#name vlan2name！设置vlan 2的名字为vlan2name2006-03-14 10:14:09 5-CONFIG:Configured from outbandsong(config-vlan)#end！退回到特权模式2006-03-14 10:14:14 5-CONFIG:Configured from outbandsong#show vlan id 2！查看vlan 2的信息VLAN Name Status Ports- - - -2 vlan2name activesong#wr！保存当前所有设置Building configuration.OK如果您想把vlan的名字改回缺省名字，如下配置song# configure terminalEnter configuration commands, one per line.

End with CNTL/Z.song(config)# interface fastEthernet 0/15！输入想要修改许可VLAN列表的Trunk口的interface id2006-03-14 11:24:15 5-CONFIG:Configured from outband!定义该接口的类型为二层Trunk口song(config-if)# switchport trunk allowed vlan remove 2！把vlan2从端口15中移出2006-03-14 11:24:31 5-CONFIG:Configured from outbandsong(config-if)#end2006-03-14 11:24:35 5-CONFIG:Configured from outbandsong# show interfaces fastEthernet 0/15 switchportInterface Switchport Mode Access Native Protected VLAN lists- - - - - - -Fa0/15 Enabled Access 1 1 Disabled 1,3-4094配置Native VLAN步骤如下：song# configure terminalEnter configuration commands, one per line.
