  Anytime I do the following configuration:
   
  Interface FastEthernet0/1
   switchport trunk encapsulation dot1q
   switchport mode trunk
   channel-group 1 mode on
  !
  interface FastEthernet0/2
   switchport trunk encapsulation dot1q
   switchport mode trunk
   channel-group 1 mode on
   
  I get the following errors message:

  Any advice will be appreciated.
