Automatic Traffic Control
– 233 –
Configuring ATC
Thresholds and
Responses
Use the Traffic > Auto Traffic Control (Configure Interface) page to set the storm
control mode (broadcast or multicast), the traffic thresholds, the control response,
to automatically release a response of rate limiting, or to send related SNMP trap
messages.
Parameters
These parameters are displayed:
◆ Storm Control – Specifies automatic storm control for broadcast traffic or
multicast traffic.
◆ Port – Port identifier.
◆ State – Enables automatic traffic control for broadcast or multicast storms.
(Default: Disabled)
Automatic storm control is a software level control function. Traffic storms can
also be controlled at the hardware level using the Storm Control menu.
However, only one of these control types can be applied to a port. Enabling
automatic storm control on a port will disable hardware-level storm control on
that port.
◆ Action – When the Alarm Fire Threshold (upper threshold) is exceeded and the
apply timer expires, one of the following control responses will be triggered.
■
Rate Control
– The rate of ingress traffic is limited to the level set by the
Alarm Clear Threshold. Rate limiting is discontinued only after the traffic
rate has fallen beneath the Alarm Clear Threshold (lower threshold), and
the release timer has expired. (This is the default response.)
■
Shutdown
– The port is administratively disabled. A port disabled by
automatic traffic control can only be manually re-enabled using the Manual
Control Release attribute.
◆ Auto Release Control – Automatically stops a traffic control response of rate
limiting when traffic falls below the alarm clear threshold and the release timer
expires as illustrated in Figure 136 on page 230. When traffic control stops, the
event is logged by the system and a Traffic Release Trap can be sent.
(Default: Disabled)
If automatic control release is not enabled and a control response of rate
limiting has been triggered, you can manually stop the rate limiting response
using the Manual Control Release attribute. If the control response has shut
down a port, it can also be re-enabled using Manual Control Release.
◆ Alarm Fire Threshold – The upper threshold for ingress traffic beyond which a
storm control response is triggered after the Apply Timer expires. (Range: 1-255
kilo-packets per second; Default: 128 kpps)
