3.3.4. Port Management - Broadcast Storm Control 

 

Broadcast storms may occur when a device on your network is malfunctioning, or if 

application programs are not well designed or properly configured. If there is too much 

broadcast traffic on your network, performance can be severely degraded or everything can 

come to complete halt. 

You can protect your network from broadcast storms by setting a threshold for broadcast 

traffic for each port. Any broadcast packets exceeding the specified threshold will then be 

dropped. 

Threshold 

Input the broadcast storm control threshold here in this field. 

Enable Port 

Check the check-box to enable the broadcast storm control function for each port.   

Button 

 

Update: 

Apply all the settings you’ve made here.
