Configuring ATC
Thresholds and
Responses
Use the Traffic > Congestion Control > 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.
Automatic storm control can be enabled for either broadcast or multicast
traffic. It cannot be enabled for both of these traffic types at the same time.
◆ 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.
