Hello,
Have an old C3560E that is uplinked to another switch using a single 10G interface.
The existing uplink interface is a trunk port and it carries 40 VLANs.
I want to migrate it to use a port channel while avoiding downtime.
Plan right now is to create the port-channel interface on both ends, duplicate the configuration from the existing interface and then plug in the 2nd cable.
I expect that spanning tree will block the port-channel and nothing bad will happen.
Then I will shut down the existing port which should change the port-channel from blocking to forwarding at this point I can just add the original interface to the port-channel.
I've been successful doing things like this on various cisco platforms over the years but never specifically with a 3560e.
Any order of operations sort of things to look out for in a scenario such as this?
