QoS > Traffic Control
The Traffic Control feature provides the ability to control the receive rate of broadcast, multicast, and
unknown unicast packets. Once a packet storm has been detected, the Switch will drop packets coming into
the Switch until the storm has subsided.

Parameter
Description
From Port / To Port
Specify the From and To port(s) to be configured.
Action
Drop
: Utilizes the hardware Traffic Control mechanism,
which means the Switch’s hardware will determine the
Packet Storm based on the Threshold value stated and
drop packets until the issue is resolved.
Shutdown
: Utilizes the Switch’s software Traffic Control
mechanism to determine the Packet Storm occurring. Once
detected, the port will deny all incoming traffic to the port
except STP BPDU packets, which are essential in keeping
the Spanning Tree operational on the Switch. If the
countdown timer has expired and yet the Packet Storm
continues, the port will be placed in rest mode and if no
action is taken will enter auto-recovery mode after a five
minute period. Choosing this option obligates the user to
configure the interval setting as well, which will provide
packet count samplings from the Switch’s chip to determine
if a Packet Storm is occurring.
Drop Threshold
(64Kbps * N)
Specify the threshold from 64 ~ 1,024,000 Kbit per second,
with steps (N) of 64Kbps. N can be from 1 to 16000.
Count Down
(0 or 5-30)
The countdown timer is set to determine the amount of
time, in minutes, that the Switch will wait before shutting
