I started to study networking and I have two cisco switches, and I want generate broadcast storm to test Spanning Tree, How do I do?
for gnu ping
This will flood ping the broadcast address however you must be the superuser to do so ( aka root ). In my very limited test sending 2 packets generated over 183 responses so make sure you do not do this on a production network for long.
you can do it easily just disable spaning make loop , connect the tow switches using tow cables , and through console go to the ports which you connect to and disable apaning tree :
from switch console conf t
interface fastethernet (interface number)
repeat this on all the ports connected between switchs , and switch will hang when connect your pc on any port
