5.6 Traffic Prioritization
5.6.1 Storm Control
This page allows you to configure the storm control settings for all switch ports.
There is a storm rate control for
Unicast
frames,
Broadcast
frames and
Unknown
(flooded)
frames.
The rate is 2^n, where n is equal to or less than 15, or "No Limit". The unit of the rate can be either
pps
(packets per second) or
kpps
(kilopackets per second). The configuration indicates the
permitted packet rate for unicast, multicast, or broadcast traffic across the switch.
Note
: frames sent to the CPU of the switch are always limited to approximately 4 kpps.
For example, broadcasts in the Management VLAN are limited to this rate. The management
VLAN is configured on the IP setup page.
The QoS Port Storm Control parameters are described below.
