Re: Broadcast/Multicast CPU usage

Use Broadcast Storm Control feature:

int ...

storm-control broadcast ...

This works well for broadcasts.

6148-GE-TX, 6548-GE-TX modules do not support this feature. Multicast storm control is supported by Gig 6500 modules only. 67xx modules have caveats with multicast control. You shouldn't use storm control for multicasts if you really use multicasts. Use rate-limiters on the 65k platform instead.
