Configure Broadcast, Unknown Unicast, and Multicast Bandwidth Limiting

Note

This procedure does not apply to XA1400 Series.

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.

About this task

Note

VSP 8600 Series does not support this feature for unknown unicast traffic.

Procedure

Enter Interface Configuration mode:

enable

configure terminal

interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]} or interface vlan <1–4059>

Note

If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
Configure broadcast and unknown unicast bandwidth limiting:

rate-limit [port {slot/port[/sub-port][-slot/port[/sub-port]][,...]}] broadcast {<1-65535> | <50-65000000>}
Configure multicast bandwidth limiting:

rate-limit [port {slot/port[/sub-port][-slot/port[/sub-port]][,...]}] multicast {<1-65535> | <50-65000000>}
Verify the configuration:

show interfaces gigabitethernet rate-limit [<1-4059> | {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

Variable Definitions

The following table defines parameters for the rate-limit command.


Variable	Value
`{<1-65535> \| <50-65000000>}`	Specifies the bandwidth limit for broadcast/unknown unicast and multicast traffic, in packets per second (pps). Note: The `<50-65000000>` range only applies to VSP 8600 Series.
port `{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}`	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.
