Create a loop storm in network "educational Purpose"

[Yusuf_Kabbara]

Hello I am working on a network with

Ring topology
X440 Switches

And I'm looking for a scenario to get a broadcast storm "loop" for test.

is there any way to do it!?

I am giving a training to client who had a similar problem but with all the configuration in place... after diagnostics we found that in one of the switches on of the ports are not configured probably..
Now we need to get the same scenario in a non-productive environment!
But when I try to "disable stpd s0" on one switch no loops is showing 

Hello Yusuf,

Are you trying to create a loop? If so, plugging them up in a physical loop and plugging in one PC should do the job.
