What is the difference between broad storm control and unicast storm control?
How it will work seperatly?

Hello,
give a look at the following link
I try to guess: we can have unicast storm when the switch is forwading frames with an unknown unicast MAC address destination. These frames are processed like broadcast / multicast and are sent to all ports in the VLAN with the exception of the source port.
So you can protect your ports from this case of traffic unicast with a destination that have never spoken.
Hope to help

Hello,
sorry my answer was only half.
Broadcast stom control instead controls the level of BW that can be used by frames with a broadcast destination.
A broadcast storm happens during a bridging loop and frames that are over the threshold are dropped anc counted as output drops in the output of show interface .
We use 1% level on gigabit and tengigabit interfaces on our network.
This can help during troubles caused by bridging loops.
hope to help
