The following first enables jumbo frames for layer 2 packets, and then sets
the MTU for port 1:

◆
When traffic exceeds the threshold specified for broadcast and
multicast or unknown unicast traffic, packets exceeding the threshold
are dropped until the rate falls back down beneath the threshold.
◆
Traffic storms can be controlled at the hardware level using this
command or at the software level using the
command. However, only one of these control types can be applied to a
port. Enabling hardware-level storm control on a port will disable
automatic storm control on that port.
