Broadcast testing, artificial storm?

Question

Computer networks

Good afternoon.
I work for an internet provider. When setting up the switch, a broadcast storm arose, which put down the entire network xD
I wondered whether to test the network for broadcast, and whether everything is set up correctly (since, according to the idea of ​​\u200b\u200bthe storm, there should not have been a storm
) there are adequate traffic and broadcast generators (of those that I found, they did not want to work adequately)
Who will help?

Answer 1

ostinato is a great package generator.

Answer 2

The most reliable broadcast packet generator that I know is an unmanaged switch with a patch cord plugged into any two ports.
the main thing is that the speed of the interfaces on it should not be less than the speed of the client interfaces on the network switches - you cannot flood a gigabit network with 100 megabit switches.

Answer 3

I recommend iperf. And here www.embeddedsystemtesting.com/2012/04/how-to-gener...
Well, you need to disable broadcast on the switches. It nafig is not needed, especially in the provider's network. It would also be good to resolve Malticast through igmp-snooping, and enable dhcp snooping.
