Why are you using full stp bridges? For the sake of your network, you should rethink this unless there's a good reason. (More likely, you should just find someone to consult with on the network side to set this up right, shouldn't take much time / expense at all)
As to your actual question, what do your new switch interface configs look like? BPDUguard isn't default as far as I remember, so I don't know what else you've set up. -Blake On Thu, May 14, 2015 at 9:16 PM, Chuck Payne <[email protected]> wrote: > Guys, > > We are currently upgrading out network gear, which is a mix Cisco Small > Business and Netgear Smart switches.
