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)#
