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: Disabled)
• 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 (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.
