6.24 IGMP Configuration
The Internet Group Management Protocol (IGMP) is an internal protocol of the
Internet Protocol (IP) suite. IP manages multicast traffic by using switches, routers,
and hosts that support IGMP. Enabling IGMP allows the ports to detect IGMP queries,
report packets, and manage IP multicast traffic through the switch. IGMP have three
fundamental types of message shown as follows:
Message
Description
Query
A message sent from the querier (IGMP router or switch)
asking for a response from each host belonging to the
multicast group.
Report
A message sent by a host to the querier to indicate that the
host wants to be or is a member of a given group indicated
in the report message.
Leave
Group
A message sent by a host to the querier to indicate that the
host has quit being a member of a specific multicast group.
The switch supports IP multicast. You can enable IGMP protocol via setting the IGMP
Configuration page to see the IGMP snooping information. IP multicast addresses are
in the range of 224.0.0.0 through 239.255.255.255.
IGMP Protocol:
Enable or disable the IGMP protocol.
IGMP Query:
Select the IGMP query function as Enable or Auto to set the switch
as a querier for IGMP version 2 multicast networks.
Last Member Query Count:
This item allows the user to specify the query
counts—1 or 2. If query count is set as 1, the switch will query whether any
member is still in the IGMP group for sending one query after the query interval.
With query count being set as 2, the switch will send two queries after the query
interval.
Last Member Query Interval:
Fill in the number in seconds as the query interval
