Layer 2 IGMP (Snooping and Query for IPv4)
– 419 –
have not requested a specific source (the only option for IGMPv1 and v2 hosts
unless statically configured on the switch), and a channel indicates a flow for which
the hosts have requested service from a specific source. For IGMPv1/v2 hosts, the
source address of a channel is always null (indicating that any source is acceptable),
but for IGMPv3 hosts, it may include a specific address when requested.
Only IGMPv3 hosts can request service from a specific multicast source. When
downstream hosts request service from a specific source for a multicast service,
these sources are all placed in the Include list, and traffic is forwarded to the hosts
from each of these sources. IGMPv3 hosts may also request that service be
forwarded from any source except for those specified. In this case, traffic is filtered
from sources in the Exclude list, and forwarded from all other available sources.
Note:
When the switch is configured to use IGMPv3 snooping, the snooping
version may be downgraded to version 2 or version 1, depending on the version of
the IGMP query packets detected on each VLAN.
Note:
IGMP snooping will not function unless a multicast router port is enabled on
the switch. This can accomplished in one of two ways. A static router port can be
manually configured (see “Specifying Static Interfaces for a Multicast Router” on
page 424). Using this method, the router port is never timed out, and will continue
to function until explicitly removed. The other method relies on the switch to
dynamically create multicast routing ports whenever multicast routing protocol
packets or IGMP query packets are detected on a port.
Note:
A maximum of up to 511 multicast entries can be maintained for IGMP
snooping. Once the table is full, no new entries are learned. Any subsequent
multicast traffic not found in the table is dropped if unregistered-flooding is
disabled (default behavior) and no router port is configured in the attached VLAN,
or flooded throughout the VLAN if unregistered-flooding is enabled (see
“Configuring IGMP Snooping and Query Parameters” on page 420).
Static IGMP Router Interface – If IGMP snooping cannot locate the IGMP querier,
you can manually designate a known IGMP querier (i.e., a multicast router/switch)
connected over the network to an interface on your switch (page 424). This
interface will then join all the current multicast groups supported by the attached
router/switch to ensure that multicast traffic is passed to all appropriate interfaces
within the switch.
Static IGMP Host Interface – For multicast applications that you need to control
more carefully, you can manually assign a multicast service to specific interfaces on
the switch (page 426).
IGMP Snooping with Proxy Reporting – The switch supports last leave, and query
suppression (as defined in DSL Forum TR-101, April 2006):
◆ When proxy reporting is disabled, all IGMP reports received by the switch are
forwarded natively to the upstream multicast routers.
