Figure 3-164 Igmp Configuration - SMC Networks 6152PL2 Management Manual

Command Attributes
• IGMP Status — When enabled, the switch will monitor network traffic to determine
which hosts want to receive multicast traffic. This is also referred to as IGMP
Snooping. (Default: Enabled)
• Act as IGMP Querier — When enabled, the switch can serve as the Querier,
which is responsible for asking hosts if they want to receive multicast traffic. This
feature is not supported for IGMPv3 snooping. (Default: Disabled)
• IGMP Leave Proxy Status — Suppresses leave messages unless received from
the last member port in the group. (Default: Disabled)
• IGMP Query Count — Sets the maximum number of queries issued for which
there has been no response before the switch takes action to drop a client from the
multicast group. (Range: 2-10; Default: 2)
• IGMP Query Interval — Sets the frequency at which the switch sends IGMP
host-query messages. (Range: 60-125 seconds; Default: 125)
• IGMP Report Delay — Sets the time between receiving an IGMP Report for an IP
multicast address on a port before the switch sends an IGMP Query out of that port
and removes the entry from its list. (Range: 5-25 seconds; Default: 10)
• IGMP Query Timeout — The time the switch waits after the previous querier stops
before it considers the router port (i.e., the interface which had been receiving
query packets) to have expired. (Range: 300-500 seconds; Default: 300)
• IGMP Version — Sets the protocol version for compatibility with other devices on
the network. (Range: 1-3; Default: 2)
Notes: 1.
All systems on the subnet must support the same version.
2.
Some attributes are only enabled for IGMPv2 and/or v3, including Act as
IGMP Querier, IGMP Report Delay and IGMP Query Timeout.
