IV-12. IGMP Snooping
The IGMP snooping software examines IGMP protocol messages within a
VLAN to discover which interfaces are connected to hosts or other devices
interested in receiving this traffic. Using the interface information, IGMP
snooping can reduce bandwidth consumption in a multi-access LAN
environment to avoid flooding the entire VLAN. The IGMP snooping feature
tracks which ports are attached to multicast-capable routers to help it
manage the forwarding of IGMP membership reports. The IGMP snooping
software responds to topology change notifications
NOTE: When "Enable IGMP Snooping" is selected, IGMP Static Router Port
can be selected using the drop down menu.
Click "Apply" to apply the settings.
When loop is detected, the Link/ACT LEDs of the
ports will raise the warning by blinking.
When loop is detected, the port will be disabled and
turned off the Link/ACT LED of the looped port.
Click Apply to save the changes.
