We have a customer that currently has 4 buildings on their property with fiber going to them all jumping from building to building, each one connected to a 3524GT-PWR via GBIC. The customer is adding another building looking to complete a fiber ring around the property. Right now I just have all the VLANs tagged on the ports that have the fiber plugged in. How do I program the 2 ports that will be connecting the fiber ring to prevent a loop? Do I need to change how the ports are currently programmed on the uplink ports now?
Not sure exactly what version the switches are on, think most of them are 5.2. I can upgrade if needed.
Any help is greatly appreciated.
