Chapter 14: IGMP Snooping Querier
164
Guidelines
The guidelines for IGMP snooping querier are listed here:
The network can have only one LAN.
The network cannot have any multicast routers.
IGMP snooping must be enabled on the switch.
IGMP snooping querier should be enabled on only one switch. Other
switches in the LAN should use IGMP snooping.
IGMP snooping querier must be applied to the VLAN on which the
queries are to be sent.
The VLAN must be assigned a routing interface with an IP address
that is a member of the same network as the host nodes and the
source node of the multicast packets. The switch adds the IP address
to the queries as its source address.
If you want to add or remove ports from the VLAN after activating
IGMP snooping querier, you must disable IGMP snooping querier,
modify the VLAN, and then enable it again.
The switch supports IGMP versions 1, 2, and 3. The switch normally
sends just version 2 messages. If it receives a version 1 message, it
sends version 1 messages on all of the ports. If the switch does not
receive any further version 1 messages for 400 seconds, the switch
reverts to sending version 2 messages.
If the switch receives a query either from a multicast router or from
another switch with IGMP snooping querier, it suspends IGMP
snooping querier and sends no further queries for 225 seconds. If the
switch does not receive any further queries, it reactivates the feature
and resumes sending queries.
IGMP snooping querier is supported on the base ports and SFP
modules.
