IGMP Snooping Configuration
The IGMP Snooping Configuration allows you to set up IGMP snooping.
IGMP snooping is used to monitor for any attached hosts who want to receive
a specific multicast service. It looks up the IP Multicast Group used for this
service and adds any port that received a similar request to that group. (This is
the screen and options displayed for a Switch in Layer 2 mode.)
• IGMP Snooping Status - If enabled, the Switch will monitor network traffic
to determine which hosts want to receive multicast traffic.
• IGMP Router Timeout - A switch port that stops receiving multicast proto-
col packets for this interval will be removed from the IGMP forwarding list.
The range is 3-5 minutes.
• IGMP Group Timeout - The time between last spotting an IGMP Report
message for an IP multicast address on a specific port and the Switch remov-
ing that entry from its list. The range is 3-5 minutes.
• Act as IGMP Querier - If enabled, the Switch will query other devices in
regards to IGMP.
