Automatic Traffic Control Commands
4-239
4
Command Usage
• 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.
• Automatic storm control is a software level control function. Traffic storms can
also be controlled at the hardware level using the
switchport packet-rate
command (page 4-228). 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.
Example
This example enables automatic storm control for broadcast traffic on port 1.
auto-traffic-control alarm-fire-threshold
This command sets the upper threshold for ingress traffic beyond which a storm
control response is triggered after the apply timer expires. Use the
no
form to
restore the default setting.
Syntax

alarm-fire-threshold
•
broadcast
- Specifies automatic storm control for broadcast traffic.
•
multicast
- Specifies automatic storm control for multicast traffic.
•
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 seconds)
Default Setting
128 kilo-packets per seconds
Command Mode
Interface Configuration (Ethernet)
Command Usage
• Once the upper threshold is exceeded, a trap message may be sent if
configured by the
snmp-server enable port-traps atc broadcast-alarm-fire
command (page 4-242) or
snmp-server enable port-traps atc
multicast-alarm-fire
command (page 4-243).
• After the upper threshold is exceeded, the control timer must first expire as
configured by the
auto-traffic-control apply-timer
command (page 4-237)
before a control response is triggered if configured by the
auto-traffic-control
action
command (page 4-241).
