IGMP host-query messages. (Range: 60-125 seconds; Default: 125)

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

seconds; Default: 300)
• IGMP Version — Sets the protocol version for compatibility with other
devices on the network. (Range: 1-2; Default: 2)
