Convert Cisco 3750 to Stack - No downtime?
Posted on 2015-01-12
I want to convert from a single switch to a stack. Easy enough to do but I was curious if I could do it without any downtime. Here is what I have. I have a single Cisco 3750 (Switch 1) that a bunch of servers are hooked up to. I have another Cisco 3750 (Switch 2) that I just added to the rack which doesn't have anything plugged into yet. I have both ready to configure into a stack. Both are essentially running as Stand Alone Masters right now.
So given that all the servers are connected to switch 1, can I hook up Switch 2 with a Stack cable, boot it up, and allow it become part of a stack? And would Switch 1 remain up without dropping any connections or require a reload?
