Description
Use the display igmp-snooping statistics
command to display IGMP Snooping statistics.
This command displays the following information:
the numbers of the IGMP general query messages, IGMP group-specific query
messages, IGMPv1 report messages, IGMPv2 report messages, IGMP leave messages
and error IGMP packets received, and the number of the IGMP group-specific
query messages sent.
When IGMPv3
Snooping is enabled, the device makes statistics of IGMPv3 messages as IGMPv2
messages.
Related commands: igmp-snooping.
Examples

1.1.4 igmp-snooping
Syntax
igmp-snooping { enable | disable }
View
System view, VLAN view
Parameters
enable:
Enables the IGMP Snooping feature.
disable:
Disables the IGMP Snooping feature.
Description
Use the igmp-snooping enable command
to enable the IGMP Snooping feature.
Use the igmp-snooping disable
command to disable the IGMP Snooping feature.
By default, the IGMP Snooping feature is
disabled.
Caution:
l
Before enabling IGMP Snooping in a VLAN, be sure to
enable IGMP Snooping globally in system view; otherwise the IGMP Snooping
setting will not take effect.
l
If IGMP Snooping and VLAN VPN are enabled on a VLAN at
the same time, IGMP queries are likely to fail to pass the VLAN. You can solve
this problem by configuring VLAN tags for the IGMP queries. For details, see igmp-snooping vlan-mapping.
Examples
# Enable the IGMP Snooping feature on the
switch.

Enable IGMP-Snooping ok.
1.1.5 igmp-snooping fast-leave
Syntax
igmp-snooping
fast-leave [ vlan vlan-list ]
undo igmp-snooping
fast-leave [ vlan vlan-list ]
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.
l
The fast leave processing function works for a port
only if the host attached to the port runs IGMPv2 or IGMPv3.
l
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).
l
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).
l
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.
Examples
# Enable IGMP fast leave processing on

1.1.6 igmp-snooping
general-query source-ip
Syntax
igmp-snooping general-query source-ip { current-interface | ip-address }
undo igmp-snooping general-query
source-ip
View
VLAN view
Parameters
current-interface:
Specifies the IP address of the current VLAN interface as the source address of
IGMP general queries. If the current VLAN interface does not have an IP
address, the default IP address 0.0.0.0 will be
used as the source IP address of IGMP general queries.
ip-address:
Specifies the source address of IGMP general queries, which can be any legal IP
address.
Description
Use the igmp-snooping general-query
source-ip command to configure the source address of IGMP general
queries.
Use the undo igmp-snooping
general-query source-ip command to restore the default.
This command can take effect only if the
IGMP Snooping querier function is enabled on the switch.
By default, the Layer 2 multicast switch
sends general query messages with the source IP address of 0.0.0.0.
Related commands: igmp-snooping querier,
igmp-snooping query-interval.
Examples
# Configure the switch to send general
query messages with the source IP address 2.2.2.2
in VLAN 3.

1.1.7 igmp-snooping group-limit
Syntax
igmp-snooping group-limit limit [ vlan
vlan-list ] [ overflow-replace ]
undo igmp-snooping group-limit [ vlan vlan-list ]
View
Ethernet port view
Parameters
limit:
Maximum number of multicast groups the port can join, in the range of 1 to 512.
overflow-replace:
Allows a new multicast group to replace an existing multicast group with the
lowest IP address.
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 group-limit
command to define the maximum number of multicast groups the port can join.
Use the undo igmp-snooping group-limit
command to restore the default setting.
If you do not specify any VLAN, the command
will take effect for all the VLANs to which the current port belongs; if you
specify a VLAN or multiple VLANs, the command will take effect for the port
only if the port belongs to the specified VLAN(s). It is recommended to specify
a VLAN or multiple VLANs to save memory.
The system default is 512.
l
To prevent bursting traffic in the network or
performance deterioration of the device caused by excessive multicast groups,
you can set the maximum number of multicast groups that the switch should
process.
l
When the number of multicast groups exceeds the
configured limit, the switch removes its multicast forwarding entries starting
from the oldest one. In this case, the multicast packets for the removed
multicast group(s) will be flooded in the VLAN as unknown multicast packets. As
a result, non-member ports can receive multicast packets within a period of
time.

Syntax
igmp-snooping group-policy acl-number [ vlan vlan-list ]
undo igmp-snooping group-policy [ vlan vlan-list ]
View
System view, Ethernet port view
Parameters
acl-number:
Basic ACL number, in the range of 2000 to 2999.
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 group-policy
command to configure a multicast group filter.
Use the undo igmp-snooping
group-policy command to remove the configured multicast group filter.
By default, no multicast group filter is
configured.
The ACL rule defines a multicast address or
a multicast address range (for example 224.0.0.1 to 239.255.255.255) and is
used to:
l Allow the port(s) to join only the multicast group(s) defined in the
rule by a permit statement.
l Inhibit the port(s) from joining the multicast group(s) defined in
the rule by a deny statement.
l
A port can belong to multiple VLANs, you can configure
only one ACL rule per VLAN on a port.
l
If no ACL rule is configured, all the multicast groups
will be filtered.
l
Since most devices broadcast unknown multicast packets
by default, this function is often used together with the function of dropping
unknown multicast packets to prevent multicast streams from being broadcast as
unknown multicast packets to a port blocked by this function.
l
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).
l
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).
Examples
# Configure a multicast group filter to

undo igmp-snooping host-aging-time
View
System view
Parameters
seconds:
Aging time (in seconds) of multicast member ports, in the range of 200 to
1,000.
Description
Use the igmp-snooping
host-aging-time command to configure the aging time of multicast member
ports.
Use the undo
igmp-snooping host-aging-time command to restore the default aging time.
By default,
the aging time of multicast member ports is 260 seconds.
The aging time of multicast member ports
determines the refresh frequency of multicast group members. In an environment
where multicast group members change frequently, a relatively shorter aging
time is required.
Related commands: display igmp-snooping
configuration.
Examples
# Set the aging time of multicast member
ports to 300 seconds.

1.1.10 igmp-snooping
nonflooding-enable
Syntax
igmp-snooping nonflooding-enable
undo igmp-snooping nonflooding-enable
View
System view
Parameters
None
Description
Use the igmp-snooping nonflooding-enable
command to enable the IGMP Snooping non-flooding function. With this
function enabled, unknown multicast packets are passed to the router ports of
the switch rather than being flooded in the VLAN.
Use the undo igmp-snooping
nonflooding-enable command to disable the IGMP Snooping non-flooding
function.
By default, the IGMP Snooping non-flooding
function is disabled, namely unknown multicast packets are flooded in the VLAN.
The difference between the IGMP Snooping
non-flooding function and the function of dropping unknown multicast packets is
in that the former passes unknown multicast packets to the router ports while
the latter directly discards unknown multicast packets.
You can configure this command only after
IGMP Snooping is enabled globally. When IGMP Snooping is disabled globally, the
configuration of the igmp-snooping nonflooding-enable command is also
removed.
l
IGMP Snooping must be enabled before you enable the
function of unknown multicast flooding suppression.
l
If the function of dropping unknown multicast packets
is enabled, you cannot enable the IGMP Snooping non-flooding function.
l
The IGMP Snooping non-flooding function and the
multicast source port suppression function cannot take effect at the same time.
If both are configured, only the multicast source port suppression function
takes effect.
Related commands: unknown-multicast drop
enable, multicast-source-deny, display multicast-source-deny

Unlike a static member port, a port
configured as a simulated member host will age out like a dynamic member port.
Related commands: igmp-snooping enable,
multicast static-group interface, multicast static-group vlan
Caution:
l
Before configuring a port as a simulated host, enable
IGMP Snooping in VLAN view first.
l
The current port must belong to the specified VLAN;
otherwise this configuration does not take effect.
Examples
# Configure Ethernet 1/0/1 in VLAN 1 as a simulated member host for
multicast source 1.1.1.1 and
multicast group 225.0.0.1.

Parameters
group-address: IP address of the multicast group to join, in the range of
224.0.0.0 to 239.255.255.255.
interface interface-list:
Specifies a port list. With the interface-list argument, you can define
one or more individual ports (in the form of interface-type interface-number)
and/or one or more port ranges (in the form of interface-type interface-number1
to interface-type interface-number2, where interface-number2
must be greater than interface-number1). The total number of individual
ports plus port ranges cannot exceed 10. For port types and port numbers, refer
to the parameter description in the “Port Basic Configuration” part
in this manual.
Description
Use the multicast static-group interface
command to configure the specified port(s) under the current VLAN interface as
static member port(s) for the specified multicast group.
Use the undo multicast static-group interface
command to remove the specified port(s) in the current VLAN as static member
port(s) for the specified multicast group.
By default, no port is configured as a
static multicast group member port.
Examples
# Configure ports Ethernet 1/0/1 to
Ethernet 1/0/3 under VLAN-interface 1 as static members ports for multicast
group 225.0.0.1.

vlan vlan-id:
Specifies the VLAN the Ethernet port belongs to, where vlan-id ranges
from 1 to 4094.
Description
Use the multicast static-group vlan
command to configure the current port in the specified VLAN as a static member
port for the specified multicast group.
Use the undo multicast static-group vlan
command to remove the current port in the specified VLAN as a static member
port for the specified multicast group.
By default, no port is configured as a
static multicast group member port.
