Hi Marc, For Etherchannel to work all ports need to have identical configuration, if you read the error message you can see that f0/23 is statically set as an access port and f0/24 is a trunk port. You'll need to change one of the port so it matches, or you can statically set the config in the port-channel interface and it should overwrite the individual port configs.

Any idea what the issue could be or how to troubleshoot? Obviously I could configure them as statically trunking but a lab requirement prevents this.
