We are replacing our core Avaya switch with a 6513. Our edge switches are mostly 3750s. I have a working config that is testing out so far.
I need to test building EtherChannels. A few buildings on campus have 2 GIG uplinks. If a building has a single existing uplink and you wish to add an etherchannel. What is the process in steps so as to not disrupt existing traffic? Can you make the config changes at the 3750 and 6513 and then just plug in the fiber at boths ends without interuption? Or is it best to do this off hours. Does the existing link drop so that you better plan to visit the console of the 3750 during the process.
