Creating LACP trunk

[nguyentuantuan16]

CCNA PT lab 6.3.4 is walking us through converting each physical port from access to trunk, then configuring the port Channel to trunk.

The Cisco CCNA book and some posts do not show this step.

Is this needed?  As I believe that creating a port-channel trunk alone was only needed.

Thanks for your input in advance.

yes you configure physical interface to be part of port-channel and once they are in a part of the port-channel, you make changes only on port-channel not individual interface (before you joining the interface to port-channel the config should be identical to be part of port-channel)

good explanation :

"converting each physical port from access to trunk "  may be needed based on current port config or switch model; and it is consider good practice.  I think books do omit this step (switchport mode trunk) since most of switches nowadays come with trunk ports and/or those ports are set to "auto-configure pug-and-play"; aka they can be access or trunking depending on device connected to it.  Try with new clean config switch; connect 2 PCs, they will be in access vlan 1 w/o any config; Also, connect another switch; it should be trunking w/o any config.
