Automatic Traffic Control Commands
16
auto-traffic-control
This command enables automatic traffic control for broadcast or multicast storms. Use the no form
to disable this feature.
Syntax
[no] auto-traffic-control {broadcast | multicast}
broadcast - Specifies automatic storm control for broadcast traffic.
multicast - Specifies automatic storm control for multicast traffic.
Default Setting
Disabled
Command Mode
Interface Configuration (Ethernet)
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. 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.
Console(config)#interface ethernet 1/1
Console(config-if)#auto-traffic-control broadcast
Console(config-if)#
auto-traffic-control action
This command sets the control action to limit ingress traffic or shut down the offending port. Use
the no form to restore the default setting.
Syntax
auto-traffic-control
{ broadcast | multicast } action { rate-control | shutdown }
no auto-traffic-control {broadcast | multicast} action
broadcast - Specifies automatic storm control for broadcast traffic.
multicast - Specifies automatic storm control for multicast traffic.
rate-control - If a control response is triggered, the rate of ingress traffic is limited based on
the threshold configured by the auto-traffic-control alarm-clear-threshold command.
shutdown - If a control response is triggered, the port is administratively disabled. A port
disabled by automatic traffic control can only be manually re-enabled.
