Problem Identification
During the event, I noticed that the performance of the main gaming network (VLAN) dropped significantly. After checking the core switch logs, I found a broadcast storm caused by a loop in one of the seating rows. I didn’t need to ask the users for more details; the high CPU usage on the gateway and the lost data packets made the cause very clear.
Technical Justification
Instead of just restarting the hardware, I decided to enable Storm Control and BPDU Guard on all access ports. I chose this method because it is a more reliable way to manage busy networks like a LAN Party. These settings prevent one bad connection from crashing the entire network, ensuring high stability for the tournament and avoiding long-term technical debt.
Resolution
As soon as these protocols were active, the connection became stable again. I performed a quick ping test to the local servers to confirm that everything was back to normal before closing the ticket.
