Quidway S8500 Series Routing Switches Chapter 3 Multicast Common Configuration Commands
Huawei Technologies Proprietary

Caution:
z You cannot enable both broadcast suppression and multicast suppression
simultaneously on the same card. Namely, once you have enabled broadcast
suppression on some ports of a card, you cannot enable multicast suppression on
the other ports of the card, and vice versa. Although the commands are based on
ports, the mutual exclusion between these two commands is based on cards.
z If multicast suppression is enabled, broadcast packets are also suppressed at the
same time, while broadcast suppression does not work on multicast packets.
z No distinction is made between known multicast and unknown multicast for
multicast suppression.
Related command: broadcast-suppression.
Example
# Set the multicast suppression ratio to 40%.
