Multicast and Broadcast Storm Control

[bartonr1998]

Hi All!

I was hoping someone could help me and advise if when multicast and broadcast storm-control are enabled on an interface does it monitor inbound and outbound traffic on that interface?

Also does he switch look collectively at the multicast + broadcast traffic % or does it look at broadcast and multicast traffic seperatley for example :

int gi0/1

storm-control broadcast level 20

storm-control multicast level  20

would the above command drop traffic when broadcast and multicast levels where 10% of the link each equaling 20% ?

Many thanks for your assistance!

My understanding yes it would, combined traffic levels exceeds it drops both broadcast /multicast traffic
Also if broadcast and mulitcast levels are applied and either level is reached this also would drop both broadcast/multicast traffic
