User’s Manual 139
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-
30 seconds, Default: 10)
IGMP Query Timeout — The time the switch waits after the previous querier stops before it considers the
router port (For example, 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: All systems on the subnet must support the same version. Some attributes are only enabled for
IGMPv2, including IGMP Report Delay and IGMP Query Timeout.
