Adding ports and removing ports on Layer 2 Etherchannel

I'm in the process of writing a plan to swap the connections over for two Ethechannels. In switch A & B I have 4 x 100 MB ports configured in a layer 2 etherchannel.

In switch C & D I have 2 x 1GB ports in configured in a layer 2 etherchannel

I need to swap these so switches A & B have 2 x 1GB etherchannel and switches C & D have 4 x 100MB etherchannel.

My plan was basically to shut each etherchannel, swap the connections over then add 2 ports to the current etherchannel on switch C & D.

On switches A & B I would simply remove the config from the interfaces which are no longer required to be part of the etherchannel.

Does this seem like a good plan?

Re: Adding ports and removing ports on Layer 2 Etherchannel

Yes looks like OK. I always follow the same.

1. Shutdown the interfaces on which you want to configure the ether-channel.

2. Do the layer 2 configs for STP, VLAN and other config.

3. Make sure that you have same config on all the ports along with the speed/duplex.

4. No shut the channels.

Thanks. If I set the speed and duplex settings of the interfaces within an etherchannel should I also di the same set etherchannel interface?
