Strict Priority
(SP) or
Weighted Round Robin
(
WRR
).
Note: Queue weights can only be changed when
Weighted Round
Robin
is selected.
Weighted Round Robin
scheduling services queues on a rotating basis
based on their queue weight (the number you configure in the queue
Weight
field). Queues with larger weights get more service than queues
with smaller weights.
Queue ID
This field indicates which Queue (0 to 7) you are configuring. Queue 0
has the lowest priority and Queue 7 the highest priority.
Weight Value
You can only configure the queue weights when
Weighted Round
Robin
is selected. Bandwidth is divided across the different traffic
queues according to their weights.

Introduction
A broadcast storm means that your network is overwhelmed with constant broadcast or multicast
traffic. Broadcast storms can eventually lead to a complete loss of network connectivity as the
packets proliferate.
Storm Control protects the Switch bandwidth from flooding packets, including broadcast packets,
multicast packets, and destination lookup failure (DLF). The
Rate
is a threshold that limits the
total number of the selected type of packets. For example, if the broadcast and multicast options
are selected, the total amount of packets per second for those two types will not exceed the limit
value.
Broadcast storm control limits the number of broadcast, multicast and unknown unicast (also
referred to as Destination Lookup Failure or DLF) packets the Switch receives per second on the
ports. When the maximum number of allowable broadcast, multicast and unknown unicast
packets is reached per second, the subsequent packets are discarded. Enable this feature to reduce
broadcast, multicast and unknown unicast packets in your network.
