By default, no filtering configured on the switch.
Note:
Each VLAN of each port can only be configured with one ACL rule.
If no ACL rule is configured or the configured port doesn't belong to the specified
VLAN, the filtering configured by this command will not take effect.
Most devices just broadcast unknown multicast packets, s o to prevent the case
where multicast data flow is sent as unknown multicast packets to the filtered ports,
this function is generally configured in combination with the unknown multicast
dropping function.
