Parameter
None
Description
Using unknown-multicast drop enable command, you can enable the unknown
multicast dropping function. Using undo unknown-multicast drop enable command,
you can disable this function.
By default, the unknown multicast dropping function is disabled.
Normally, if the multicast address of multicast data packet received by the switch is not
registered on this switch, this packet will be broadcasted within this VLAN. Whereas
after enabling the unknown multicast dropping feature, when receiving multicast data
packet with unregistered multicast address, the switch will drop this packet. In this way,
the bandwidth is saved, and the efficiency of the system is enhanced.
Example
# Enable the switch to drop multicast data packets with unregistered multicast
addresses.
[Quidway] unknown-multicast drop enable
