I create the channel-group so that you can make one change to affect all
ports.
I believe that you need the channel-group anyways for it to work.

Subject: Ether-channel and port-channel
Hi groups,
I found confusing configuration in lab workbook. The configuration is
below.
The task:
Create Ether-channel on fa0/23 - fa0/24, as trunk with encapsulation
isl. Allowed vlan is 1,2,3.
Answer:
interface fa0/23
switchport mode trunk
switchport trunk encapsulation isl
switchport trunk allowed vlan 1,2,3
no ip address
channel-group 1
!
interface fa0/24
switchport mode trunk
switchport trunk encapsulation isl
switcport trunk allowed vlan 1,2,3
no ip address
channel-group 1
!
interface port-channel1
switchport mode trunk
switchport trunk encapsulation isl
switchport trunk allowed vlan 1,2,3
no ip address
My question:
Should we create interface port-channel in this case? AFAIK, port-channel
is needed if we want to create layer 3 interface. If we want to create
ether-channel, we just add 'channel-group' command on interfaces. There is
no need create interface port-channel.
Thank you for your response,
Rivel
