Broadcast problem

 

 

Currently I implement a meraki LAN network (1 switch core 425 and 14 switch ccess 225). 

 

My network works without problem, but I have a question;

 

How do I know when I have broadcast problems on my network?

any

Is there a configuration that avoids broadcast problems?

Check storm control options:

I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.

From my experience, unless you've ot a very flat network, limited bandwidth or lots of old client devices, broadcast storms are pretty rare. That said, they can definitely still occur.

 

To answer your question, you know you have broadcast storms if your network grinds to a halt and the broadcast counters on the switch ports are increasing at an incredibly high rate.

 

As @alemabrahao wrote, you can look into using storm control as a preventing mechanism.
