You can configure the Switch to forward multicast traffic intelligently. Based on the IGMP query and report
messages, the Switch forwards traffic only to the ports that request multicast traffic. This prevents the Switch
from broadcasting the traffic to all ports and possibly disrupting network performance.
IGMP Status. When enabled, the Switch will monitor network traffic to determine which hosts want to receive
multicast traffic. This is also referred to as IGMP Snooping. (Default: Enabled).
IGMP Querier Status. 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: 5-25 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 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)
