Configuring IGMP Snooping
Description
Enables IGMP snooping on a per-VLAN basis. The
default is enabled.
If the global setting is disabled, all VLANs
Note
are treated as disabled, whether they are
enabled or not.
Tracks IGMPv3 membership reports from individual
hosts for each port on a per-VLAN basis. The default
is enabled.
Enables the software to remove the group state when
it receives an IGMP Leave report without sending an
IGMP query message. This parameter is used for
IGMPv2 hosts when no more than one host is present
on each VLAN port. The default is disabled.
Sets the interval that the software waits after sending
an IGMP query to verify that no hosts that want to
receive a particular multicast group remain on a
network segment. If no hosts respond before the last
member query interval expires, the software removes
the group from the associated VLAN port. Values
range from 1 to 25 seconds. The default is 1 second.
Configures a snooping querier on an interface when
there is no multicast router in the VLAN to generate
queries. The default is disabled.
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.
Configures a static connection to a multicast router.
The interface to the router must be in the selected
VLAN.
