===== On the Switch =====
1) Create the virtual port channel:
interface Port-channel2
description Server1
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
spanning-tree portfast trunk
2) On each physical switch interface, include it as part of the group.
interface GigabitEthernet2/0/1
description Server1 port 1
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
spanning-tree portfast trunk
channel-group 2 mode active
interface GigabitEthernet2/0/2
description Server1 port 2
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
spanning-tree portfast trunk
channel-group 2 mode active
interface GigabitEthernet2/0/3
description Server1 port 3
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
spanning-tree portfast trunk
channel-group 2 mode active
