■ Query Interval – The frequency (between 60 and 125 seconds) at which the
switch sends IGMP host-query messages. The default is 125 seconds.
■ Query Report Delay – The time (between 5 and 25 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 default
is 10 seconds.
■ Router Port Expire Time – The time (between 300 and 500 seconds) the switch
waits after the previous querier stops querying before it determines that the
interface (which had been receiving query packets) is no longer attached to a
querier. The default is 300 seconds.
Note – All systems on the subnet must support the same version.
Some attributes are only enabled for IGMPv2, including IGMP Report Delay
and Router Port Expire Time.
