The page includes the following fields:
Object Description
•
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 )
•
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.
This feature is not supported for IGMPv3 snooping.
(Default: Disabled )
•

•
IGMP Query Interval Sets the frequency at which the switch sends IGMP host-query messages.
Range: 60-125 seconds;

port before the switch sends an IGMP Query out of that port and removes the
entry from its list.
Range: 5-25 seconds;

•
IGMP Query Timeout
The time the switch waits after the previous querier stops before it considers the
