cisco 交换机配置trunk被拒绝  

 

 

 

交换机在接口模式下输入switchport mode trunk 提示：

Command rejected: An interface whose trunk encapsulation is "Auto" can not be co
nfigured to "trunk" mode.

 

解决方法：

(config-if)#switchport mode trunk 
Command rejected: An interface whose trunk encapsulation is "Auto" can not be configured to "trunk" mode.
(config-if)#switchport trunk encapsulation dot1q 
(config-if)#switchport mode trunk 
(config-if)#switchport trunk all
(config-if)#switchport trunk allowed vlan all
