Configuring IGMP
This protocol allows a host to inform its local switch/router that it wants
to receive transmissions addressed to a specific multicast address group.
Use the IGMP Configuration screen to set key parameters for multicast
filtering as shown below.
Note: The default values are indicated in the sample screen.
Parameter Description
IGMP Status If enabled, the switch will monitor network traffic to
determine which hosts want to receive multicast traffic.
Act as IGMP Querier If enabled, the switch can serve as the “querier”, which is
responsible for asking hosts if they want to receive multicast
traffic. (Not supported in the current firmware release.)
IGMP Query
Count
The maximum number of queries issued for which there has
been no response before the switch takes action to solicit
reports.
IGMP Report
Delay
The time (in seconds) between receiving an IGMP Report
for an IP multicast address on a port before the switch sends
an IGMP Query out that port and removes the entry from
its list.
