Switch 1

config t

int port-channel 1
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate

exit

int range gi3/1/1-4
 switchport trunk encapsulation dot1q
 switchport mode trunk
 switchport nonegotiate
 channel-group 1 mode active

exit


Configure the same thing on the switch 2

Make sure to configure the new switch as VTP transparent before creating a trunk port.

You can later then, change to client if you want.

Infamus' solution is the answer, but you might need to correct a typo :-)

int range gi3/1/1-4  ---->>> int range gi3/1/1 - 4   (you usually need a space between the - )


So...


config t

int po1
switchport trunk encapsulation dot1q 
switchport mode trunk
switchport nonegotiate

exit

int range gi3/1/1 - 4
 switchport trunk encapsulation dot1q 
 switchport mode trunk
 switchport nonegotiate
 channel-group 1 mode active

exit
