Use the
undo multicast-suppression
command to disable the broadcast suppression
function.
The default multicast suppression ratio is 100%.
You can use the
multicast-suppression
command repeatedly. The effective multicast
suppression ratio value is the one last updated.
Caution:
z
You cannot enable both multicast suppression and broadcast 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.
