Chapter 39 Configuring Traffic Storm Control

– WS-X6748-GE-TX 100Mbps ports: 0.03 percent or less
– WS-X6716-10G-3C / 3CXL Oversubscription Mode: 0.29 percent or less
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 making up the incoming traffic,
the actual enforced level might differ from the configured level by several percentage points.
This example shows how to enable multicast traffic storm control on Gigabit Ethernet interface 3/16 and
how to configure the traffic storm control level at 70.5 percent:
Router# configure terminal
Router(config)# interface gigabitethernet 3/16
Router(config-if)# storm-control multicast level 70.5
Router(config-if)# end
This example shows how the traffic storm control level configured for one mode affects all other modes
that are already configured on the Gigabit Ethernet interface 4/10:
Router# show run inter gig4/10
Building configuration...
Current configuration : 176 bytes
!
Router# interface GigabitEthernet4/10
Router# switchport
Router# switchport mode access
Router# storm-control broadcast level 70.00
Router# storm-control multicast level 70.00
Router# spanning-tree portfast edge
Router# end
Router# configure terminal
Router(config)# interface gigabitethernet 4/10
Router(config-if)# storm-control unicast level 20
Router(config-if)# end

Displaying Traffic Storm Control Settings
To display traffic storm control information, use the commands described in Table 39-1.
Table 39-1 Commands for Displaying Traffic Storm Control Status and Configuration
Command Purpose
Router# show interfaces [{ type
1
slot/port } |
{port-channel
number }] switchport
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
Displays the administrative and operational status of all
Layer 2 LAN ports or the specified Layer 2 LAN port.
Router# show interfaces [{ type
1
slot/port } |
{port-channel
number }] counters storm-control
Router# show interfaces counters storm-control [module
slot_number ]
Displays the total number of packets discarded for all
three traffic storm control modes, on all interfaces or on
the specified interface.
