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?
