Step 3 Use the following commands to specify the upper rate limit of the broadcast packets, multicast 
packets and unknown unicast frames in pps:
storm-control pps
Configure the storm control mode as pps (packets per second) on the port. In PPS mode, the 
upper rate limit of the broadcast packets, multicast packets and unknown unicast frames can 
only be specified in packets per second.
storm-control {broadcast | multicast | unicast} pps 
rate
broadcast | multicast | unicast: Enable broadcast rate limit, multicast rate limit or unknown 
unicast rate limit on the port.
rate:
 Specify the upper rate limit for receiving broadcast packets, multicast packets and 
unknown unicast frames on the port. The packet traffic exceeding the rate will be discarded. 
The valid rate values are from 1 to 1488000 packets per second.
Use the following commands to specify the upper rate limit of the broadcast packets, multicast 
packets and unknown unicast frames in kbps or ratio:
no storm-control pps
Ensure the pps mode is disabled on the port. 
storm-control {broadcast | multicast | unicast}  {kbps | ratio} 
rate
broadcast | multicast | unicast: Enable broadcast packets rate limit, multicast packets rate limit 
or unknown unicast frames rate limit on the port.
kbps: Configure the storm control mode as kbps. In this mode, the upper rate limit is specified 
in kilo-bits per second.
ratio: Configure the storm control mode as ratio. In this mode, the upper rate limit is specified 
as a percentage of the bandwidth. 
rate:
 Specify the upper rate limit for receiving broadcast packets, multicast packets and 
unknown unicast frames on the port. The packet traffic exceeding the rate will be discarded. 
For kbps, the valid rate values are from 1 to 1000000 kbps; for ratio, the valid rate values are 
from 1 to 100 percent.
Step 4 show storm-control {interface [fastEthernet

]} 
Verify the storm control configurations of the port or LAG. If no port or LAG is specified, it 
displays the storm control configuration for all ports or LAGs.
Step 5 end
Return to privileged EXEC mode.
Step 6 copy running-config startup-config
Save the settings in the configuration file.
