Configuring Port-Based Traffic Control
SUMMARY STEPS
1. enable
2. configure terminal
3. interface interface-id
4. storm-control {broadcast | multicast | unicast} level {level [level-low] | bps bps [bps-low] | pps pps
[pps-low]}
5. storm-control action {shutdown | trap}
6. end
7. show storm-control [interface-id] [broadcast | multicast | unicast]
8. copy running-config startup-config
DETAILED STEPS
Command or Action
Step 1
enable
Example:
Switch> enable
Step 2 configure terminal
Example:
Switch# configure terminal
Step 3
interface interface-id
Example:
Switch(config)# interface
gigabitethernet1/0/1
Step 4 storm-control {broadcast | multicast
| unicast} level {level [level-low] | bps
bps [bps-low] | pps pps [pps-low]}
Example:
Switch(config-if)# storm-control
unicast level 87 65
OL-29048-01
Purpose
Enables privileged EXEC mode. Enter your password if prompted.
Enters the global configuration mode.
Specifies the interface to be configured, and enter interface configuration mode.
Configures broadcast, multicast, or unicast storm control. By default, storm control
is disabled.
The keywords have these meanings:
• For level, specifies the rising threshold level for broadcast, multicast, or
unicast traffic as a percentage (up to two decimal places) of the bandwidth.
The port blocks traffic when the rising threshold is reached. The range is
0.00 to 100.00.
• (Optional) For level-low, specifies the falling threshold level as a percentage
(up to two decimal places) of the bandwidth. This value must be less than
or equal to the rising suppression value. The port forwards traffic when
traffic drops below this level. If you do not configure a falling suppression
level, it is set to the rising suppression level. The range is 0.00 to 100.00.
