SW1(config-if-range)#channel-group 1 mode desirable

Creating a port-channel interface Port-channel 1  

!  

SW1(config-if-range)#interface port-channel 1  

SW1(config-if)#switchport trunk encapsulation dot1q   

SW1(config-if)#switchport mode trunk  SW1(config-if)#exit 

SW-2:

SW2(config)#interface range e0/0-2  

SW2(config-if-range)#channel-group 1 mode auto
