 Note:
z The fast leave processing function works for a port only if the host attached to the
port runs IGMPv2 or IGMPv3.
z The configuration performed in system view takes effect on all ports of the switch if
no VLAN is specified; if one or more VLANs are specified, the configuration takes
effect on all ports in the specified VLAN(s).
z The configuration performed in Ethernet port view takes effect on the port no matter
which VLAN it belongs to if no VLAN is specified; if one or more VLANs are specified,
the configuration takes effect on the port only if the port belongs to the specified
VLAN(s).
z If fast leave processing and unknown multicast packet dropping are enabled on a
port to which more than one host is connected, when one host leaves a multicast
group, the other hosts connected to port and interested in the same multicast group
will fail to receive multicast data for that group.
