Layer 3 Management 24-Port 10/100 + 2-Port Gigabit Ethernet Switch
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.
