In order to protect your network form congestion by broadcast floods, you have to setup broadcast storm control. This tutorial will showcase how to set this up!
1. Access your device by entering its IP address in the browser address line and login by using the device’s credential
2. Navigate to Advanced Application > Broadcast Storm Control
3. Activate Broadcast Storm Control here
4. Type in a value as how many Packets of the corresponding types should be allowed per port
To get the right values here, monitoring the general traffic would be a good idea as setting this value too low would cause network problems.
