3. 实验步骤

 

 

Switch#vlan da

% Warning: It is recommended to configure VLAN from config mode,

  as VLAN database mode is being deprecated. Please consult user

  documentation for configuring VTP/VLAN in config mode.

 

Switch(vlan)#vlan 2 name cisco

VLAN 2 added:

    Name: cisco

Switch(vlan)#exit

APPLY completed.

Exiting....

Switch#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

Switch(config)#int f0/1

Switch(config-if)#switch mode trunk//把f0/1配置成TRUNK模式

Switch(config-if)#exit

Switch(config)#int f0/2

Switch(config-if)#switch mode access

Switch(config-if)#switch access vlan 2//把f0/2划分到VLAN2

Switch(config-if)#
