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.
(Default: Enabled)
• 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: 1-2; Default: 2)
Notes: 1.
All systems on the subnet must support the same version.
2. Some attributes are only enabled for IGMPv2, including IGMP Report Delay
and IGMP Query Timeout.
