◆ Using both rate limiting and storm control on the same interface may lead to
unexpected results. It is therefore not advisable to use both of these commands
on the same interface.
Example
The following shows how to configure broadcast storm control at 600 packets per
second:
Console(config)#interface ethernet 1/5
Console(config-if)#switchport broadcast packet-rate 600
Console(config-if)#
