CHAPTER 9
Broadcast Storm Commands
Use these commands to limit the number of broadcast, multicast and destination lookup failure
(DLF) packets the Switch receives per second on the ports.
 Broadcast storm control implementation differs across Switch models.
• Some models use a single command (bmstorm-limit) to control the combined rate of
broadcast, multicast and DLF packets accepted on Switch ports.
• Other models use three separate commands (broadcast-limit, multicast-
limit, dlf-limit) to control the number of individual types of packets accepted on
Switch ports.
See Section 9.2 on page 46 and Section 9.3 on page 46 for examples.
