Static aggregator

See

Static channel group

.

Static channel group

A static channel group, also known as a static aggregator, enables a number of ports to be
manually configured to form a single logical connection of higher bandwidth. By using
static channel groups you increase channel reliability by distributing the data path over
more than one physical link.

Storm-control

Storm-control enables you to specify the threshold level for broadcasting, multicast, or
destination lookup failure (DLF) traffic for a port. Storm-control limits the specified traffic
type to the specified threshold.

“Storm control” on page 14.12
