372 Ethernet Configuration Commands
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 and duplex commands control interface link speeds and auto-
negotiation. If either speed or duplex 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 and prefers full duplex over
half duplex.
