Starting from the beginning. Fix PortChannel 1.
conf t
int po 1
switchport trunk encap dot1q
switchport mode trunk
verify by show int trunk
po1 will now show up in trunks .
Now on to actual step to create PO/trunk with SW20.
I created po 11
conf t
int po 11
switchport trunk encap dot1q
switchprot mode trunk
then config interfaces
conf t
int range e 0/0 - 2
switchport trunk encap dot1q
switchport mode trunk
channel-group 11 mode active
All seemed to be working fine after that. Please let me know if this doesn't look correct for some reason.
