Configuring Traffic Storm Control
S e n d f e e d b a c k t o n x 5 0 0 0 - d o c f e e d b a c k @ c i s c o . c o m
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.
Traffic storm control uses a 10-microsecond interval that can affect the operation of traffic storm control.
Note
To enable traffic storm control on an interface, perform this task:
Command
Step 1
switch# configure terminal
Step 1
switch(config)# interface {ethernet
slot/port | port-channel number}
Step 2
switch(config-if)# storm-control
{broadcast | multicast | unicast} level
percentage[.fraction]
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:
Command
switch# show interface [ethernet slot/port
| port-channel number] counters
storm-control
switch# show running-config interface
Displaying Traffic Storm Control Counters
You can display the counters the Cisco Nexus 5000 Series switch maintains for traffic storm control
activity.
