Select the enable checkbox to use this IGMP snoop querier configuration
with the VLAN listed. Once a parameter has been enabled, the red "X" in
the enabled column of the Igmp Snoop Querier Vlan Config table displays
a green checkmark, designating the configuration as enabled.
Define the igmpV1, igmpV2 or igmpV3 version from the drop-down menu.
The snooping controller does not rely on IGMP group leave
announcements to determine when entries should be removed from the
forwarding table. It implements a last membership query mechanism
(such as the router-side functionality of the IGMP protocol as described
in the IGMP and MLD specifications) on all its non-router ports. Define a
timeout value as required between 60 - 300 seconds. Hosts that have
silently opted out without sending a leave message are discarded if they
do not respond with join/reports on the next query interval.
Defines the maximum response time for the controller to receive a report.
If the controller does not receive a report, it discards this port. If it
receives a response from a wireless client it updates it's IGMP snoop
table with the reported multicast group membership. In case of IGMP
reports from wired ports, it simply forwards to multicast router ports, as
IGMP snooping is conducted only for wireless clients and all wired ports
are flooded for multicast packets. Define a value between 1 - 25
seconds.
Displays whether a particular configuration has been enabled/disabled.
Once a parameter has been enabled, the red "X" in the enabled column
of the Igmp Snoop Querier Vlan Config table displays a green checkmark,
designating the configuration as enabled.
Displays the configured querier IP address on the controller used while
generating the general IGMP query.
