Layer 2 Switching Commands 391
On a storm control enabled interface, if the ingress rate of that type of packet
(L2 broadcast, multicast, or unicast) is greater than the configured threshold
level (as a percentage of port speed or as an absolute packets-per-second rate),
the switch forwarding-plane discards the excess traffic.
The
speed command controls interface link speeds and auto-negotiation. If
speed is set to something other than auto, auto-negotiation is disabled on the
interface. Auto-negotiation will link at the highest possible speed supported
on the interface at full duplex.
