Hello, We have around 40 numbers of x440-24P EXOS based Switches in our campus. Some of the users connected in these Switches using different open source softwares to block the network or limit the bandwidth of others who are connected in the same network by using Network IP scanning. After IP Scanning these users select multiple users and the bandwidth for them. How to block these applications in EXOS Switches? Please help us to fix this issue.
