thx KCotreau, I simply think a few hundred broadcast message per second should not cause any issue... Do you think a Cisco Cat6.5k can handle thousands, 10ks, or > broadcast messages per second?

comment Broadcast storm
because i want to know how many broadcast messages can a switch handle specifically. I am sending hundreds of broadcast message per second, causing high CPU load on switch, and caused some unintended side effects to other applications (ping message dropped by switch, other application thought network is down, and triggered failover)

I'm referring to CPU load on a switch.

Thanks Chris, I'm seeing an application causing a broadcast storm, generated by large amount of broadcast message. After some research, I found out broadcast & multicast messages are handled by software level rather than hardware, the high CPU load causes packet drops. That's why I'd like to know how a switch (managed/unmanaged) handles each of the message types.
