CHAPTER 8

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 8.2 on page 46 and Section 8.3 on page 46 for examples.
