Chapter 15 Configuring Traffic Storm Control
Configuring Traffic Storm Control
–
100 percent means no traffic storm control.
–
0.0 percent suppresses all traffic.
Because of hardware limitations and the method by which packets of different sizes are counted, the level
percentage is an approximation. Depending on the sizes of the frames that make up the incoming traffic,
the actual enforced level might differ from the configured level by several percentage points.
Configuring Traffic Storm Control
You can set the percentage of total available bandwidth that the controlled traffic can use.
Note
Traffic storm control uses a 10-microsecond interval that can affect the operation of traffic storm control.
To enable traffic storm control on an interface, perform this task:
This example shows how to configure unicast traffic storm control for Ethernet interface 1/4:
switch#
configure terminal
switch(config)#
interface ethernet 1/4
switch(config-if)#
storm-control unicast level 40
Verifying Traffic Storm Control Configuration
To display traffic storm control configuration information, perform one of these tasks:
Displaying Traffic Storm Control Counters
You can display the counters the Cisco Nexus 5000 Series switch maintains for traffic storm control
activity.
