Layer 2 IGMP (Snooping and Query for IPv4)
– 436 –
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 an IPv4 Multicast Router”
on page 441). 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 1024 multicast entries can be maintained for IGMP
snooping and 255 entries for Multicast Routing when both of these features are
enabled. 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 437).
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 441). 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 443).
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.
◆
Last Leave: Intercepts, absorbs and summarizes IGMP leaves coming from IGMP
hosts. IGMP leaves are relayed upstream only when necessary, that is, when the
last user leaves a multicast group.
◆
Query Suppression: Intercepts and processes IGMP queries in such a way that
IGMP specific queries are never sent to client ports.
The only deviation from TR-101 is that report suppression, and
the marking of IGMP
traffic initiated by the switch with priority bits as defined in R-250 is not supported.
Note:
IGMP Query (Layer 2 or 3) – IGMP Query can be enabled globally at Layer 2,
but can also be enabled for individual VLAN interfaces at Layer 3 (see “Configuring
