Configure broadcast, unknown unicast, and multicast bandwidth limiting to limit the amount of ingress traffic on a port. The switch drops traffic that violates the bandwidth limit.
default rate-limit [port {slot/port[/sub-port][-slot/port[/sub-port]][,...]}] {broadcast | multicast}
no rate-limit [port {slot/port[/sub-port][-slot/port[/sub-port]][,...]}] {broadcast | multicast}
rate-limit[port {slot/port[/sub-port][-slot/port[/sub-port]][,...]}] broadcast <1-65535>
rate-limit [port {slot/port[/sub-port][-slot/port[/sub-port]][,...]}] multicast <1-65535>
Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
The default is disabled (no rate limit).
