l Act as IGMP Querier — Enables the switch as Querier. When Querier is enabled, the switch can serve as the Querier, which is responsible for asking
hosts if they are supposed to receive multicast traffic.
l IGMP Query Count (2–10) — Sets the maximum number of queries issued for which there has been no response before the switch takes action to
solicit reports. (The range is 2 to 10.)
l IGMP Query Interval (60–125) — Sets the frequency at which the switch sends IGMP host-query messages. (The range is 60 to 125.)
l IGMP Report Delay (5–30) — Sets the time (in seconds) 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. (The range is 5 to 30.)
l IGMP Query Timeout (300–500) — Sets the time the switch waits after the previous querier has stopped querying before it takes over as the querier.
(The range is 300 to 500.)
l IGMP Version — Sets the protocol version for compatibility with other devices on the network (1 or 2).
