Verifying Traffic Storm Control Configuration; Configuring Traffic Storm Control - Cisco AP775A - Nexus Converged Network Switch 5010 Configuration Manual

Configuring Traffic Storm Control

• Specify the level as a percentage of the total interface bandwidth:
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.

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
OL-16597-01
◦ The level can be from 0 to 100.
◦ The optional fraction of a level can be from 0 to 99.
◦ 100 percent means no traffic storm control.
◦ 0.0 percent suppresses all traffic.
Command or Action
switch# configure terminal
switch(config)# interface {ethernet slot/port |
port-channel number}
switch(config-if)# storm-control {broadcast |
multicast | unicast} level percentage[.fraction]
