How to add an additional port to LACP?

Question

Cisco

I need to move uplinks from one switch in the stack to another without interrupting access. Configured on additional ports channel-group 10 mode active (already existing group). But the current configuration with interface portchannel 10 was not added to them. I added the settings manually: trunk port and allowed VLANs. After that, changes to the interface portchannel only affect the ports that were added when the channel-group was created, and the changes do not apply to new ports.

Answer 1

So it should be added, when adding a new port, you need to copy the config to it from the physical port (which already works in the group) and only after that adding the config on the portchannel, the config will be added on all ports.

Answer 2

Those. first transfer all the settings, then add the port to the channel-group and then the changes to the portchannel will be applied to the old and new ports?
