View
System view, Ethernet port view
Parameters
vlan
vlan-list
: Specifies a VLAN list. With the
vlan-list
argument, you can provide one or
more individual VLAN IDs (in the form of
vlan-id
) and/or one or more VLAN ID ranges
(in the form of
vlan-id1 to
vlan-id2
, where
vlan-id2
must be greater than
vlan-id1
). The
effective range for a VLAN ID is 1 to 4094 and the total number of individual VLANs plus
VLAN ranges cannot exceed 10.
Description
Use the
igmp-snooping fast-leave
command to enable IGMP fast leave processing.
Use the
undo
igmp-snooping fast-leave
command to disable IGMP fast leave
processing.
By default, IGMP fast leave processing is disabled.
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 or non-flooding 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.
