IGMP querier:
1. Query-interval: Click in the “query-interval” textbox and specify a new
number from 1 ~ 18000. The query-interval field is used to set the time
(in seconds) between transmitting IGMP queries. Entries between 1 and
18000 seconds are allowed. Default = 125.
2. Max-response-time: Click in the “max-response-time” textbox and
specify a new number from 1 ~ 124. This determines the maximum
amount of time in seconds allowed before sending an IGMP response
report. The max-response-time field allows an entry between 1 and 124
(seconds). Default = 10.
IGMP passive snooping:
1. Report suppression: Click “report suppression” drop-down menu from
“report suppression” drop-down list to choose “Enable” or “Disable” for
the switch. Use this command to enable report suppression for IGMP
version 1 and version 2. Report suppression does not apply to IGMP
version 3, and is turned off by default for IGMP versionn1 and IGMP
version 2 reports. The switch uses IGMP report suppression to forward
only one IGMP report per multicast router query to multicast devices.
When IGMP router suppression is enabled, the switch sends the first
IGMP report from all hosts for a group to all the multicast routers. The
switch does not send the remaining IGMP reports for the group to the
multicast routers. This feature prevents duplicate reports from being
sent to the multicast devices.
