IGMP querier:
1. Query-interval: Select 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: Select 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: Select “report suppression” drop-down menu
from “report suppression” drop-down list to choose “Enable” or
“Disable” for the Ethernet Extender 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 version 1 and IGMP version 2
reports. The Ethernet Extender 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 Ethernet Extender Switch sends the first IGMP report
from all hosts for a group to all the multicast routers. The Ethernet
Extender 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.
2. Update Setting: Select “Update Setting” button when you finished
IGMP Snooping.
