Port-channel note
We have the following setup of a port-channel between to Catalyst 3750s - SW1 Gi0/1 and Gi0/2, bundled in a port-channel are connected to Gi0/1 and Gi0/2 on SW2:
SW1:
interface GigabitEthernet1/0/1

switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,2,3,4
switchport mode trunk

In order for the port-channel to form successfully, all port members need to have identical: › Continue reading
