DETAILED STEPS
PurposeCommand or Action

Step 1
Example:
Switch> enable
Enters the global configuration mode.configure terminal

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.
