Broadcast, unknown Unicast, and Multicast rate limiting

The num variable specifies the maximum number of packets per second. It can be any number that 
is a multiple of 65536, up to a maximum value of 2147418112 for 10G and multiple of 8192 for 
1G. If you enter the multicast limit or unknown-unicast limit command, multicast or 
unknown-unicast packets are included in the corresponding limit. If you specify 0, limiting is 
disabled. If you specify a number that is not a multiple of 65536, the software rounds the number 
to the next multiple of 65536. Limiting is disabled by default.

Viewing rate limits set on BUM traffic

You can use the show run interface command to display the broadcast, multicast, and 
unknown-unicast limits configured on each interface of the device. In addition to show run 
interface, you can use the show rate-limit broadcast command to display the broadcast, multicast, 
and unknown-unicast limits configured on the device.

Use the show run interface command to view the broadcast, multicast, and unknown-unicast limit 
configured on each interface as shown in the following example.
