PurposeCommand or Action
Enables privileged EXEC mode. Enter your password if prompted.enable
Step 1
Example:
Switch> enable
Enters the global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 2
Specifies the interface to be configured, and enter interface configuration mode.
interface interface-id
Example:
Switch(config)# interface
gigabitethernet1/0/1
Step 3
Configures broadcast, multicast, or unicast storm control. By default, storm control
is disabled.
storm-control {broadcast | multicast
| unicast} level {level [level-low] | bps
bps [bps-low] | pps pps [pps-low]}
Step 4
The keywords have these meanings:
Example:
Switch(config-if)# storm-control
unicast level 87 65
•
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.
If you set the threshold to the maximum value (100 percent), no limit is
placed on the traffic. If you set the threshold to 0.0, all broadcast, multicast,
and unicast traffic on that port is blocked.
•
For bps bps, specifies the rising threshold level for broadcast, multicast, or
unicast traffic in bits per second (up to one decimal place). The port blocks
traffic when the rising threshold is reached. The range is 0.0 to
10000000000.0.
•
(Optional) For bps-low, specifies the falling threshold level in bits per second
(up to one decimal place). It can be less than or equal to the rising threshold
level. The port forwards traffic when traffic drops below this level. The
range is 0.0 to 10000000000.0.
•
For pps pps, specifies the rising threshold level for broadcast, multicast, or
unicast traffic in packets per second (up to one decimal place). The port
