Chapter 14 Configuring IGMP Snooping
Configuring IGMP Snooping Parameters
The following example shows configuring IGMP snooping parameters for VLAN 5:
switch# configure terminal
switch(config)# vlan 5
switch(config-vlan)# ip igmp snooping last-member-query-interval 3
switch(config-vlan)# ip igmp snooping querier 172.20.52.106
switch(config-vlan)# ip igmp snooping explicit-tracking
switch(config-vlan)# ip igmp snooping fast-leave
switch(config-vlan)# ip igmp snooping report-suppression
switch(config-vlan)# ip igmp snooping mrouter interface ethernet 1/10
switch(config-vlan)# ip igmp snooping static-group 230.0.0.1 interface ethernet 1/10
switch(config-vlan)# end
switch#
Step 4
switch(config-vlan)# ip igmp snooping
Enables IGMP snooping for the current VLAN. The
default is enabled.
Note If IGMP snooping is enabled globally, this
command is not required.
switch(config-vlan)# ip igmp snooping
explicit-tracking
Tracks IGMPv3 membership reports from individual
hosts for each port on a per-VLAN basis. The default
is enabled on all VLANs.
switch(config-vlan)# ip igmp snooping
fast-leave
Supports IGMPv2 hosts that cannot be explicitly
tracked because of the host report suppression
mechanism of the IGMPv2 protocol. When you enable
fast leave, the IGMP software assumes that no more
than one host is present on each VLAN port. The
default is disabled for all VLANs.
switch(config-vlan)# ip igmp snooping
last-member-query-interval seconds
Removes the group from the associated VLAN port if
no hosts respond to an IGMP query message before the
last member query interval expires. Values range from
1 to 25 seconds. The default is 1 second.
switch(config-vlan)# ip igmp snooping
querier IP-address
Configures a snooping querier when you do not enable
PIM because multicast traffic does not need to be
routed. The IP address is used as the source in
messages. The default is disabled.
switch(config-vlan)# ip igmp snooping
report-suppression
Limits the membership report traffic sent to
multicast-capable routers. When you disable report
suppression, all IGMP reports are sent as is to
multicast-capable routers. The default is enabled.
switch(config-vlan)# ip igmp snooping
mrouter interface interface
Configures a static connection to a multicast router.
The interface to the router must be in the selected
VLAN. You can specify the interface by type and
number.
switch(config-vlan)# ip igmp snooping
static-group group-ip-addr [source
source-ip-addr] interface interface
Configures an interface belonging to a VLAN as a
static member of a multicast group. You can specify
the interface by type and number.
