This page can be used as a troubleshooting tool if a problem related to IGMP snooping occurs.
IGMP snooping is enabled when profiles are specified on the ProAV profile page.
In this page, IGMP snooping settings can be changed and the IGMP snooping operating status checked separately for each ProAV profile.
First, select a profile from the profile select box in the upper left corner of the page.
If a ProAV profile has not been specified, specify the profile on the ProAV Profiles page.
IGMP snooping learning status can be checked for each ProAV profile.
If a group is selected in the "Multicast Group" select box, the corresponding IGMP report/query learning status is displayed.
Mouse-over the port with the learning status displayed to show a tooltip with detailed IGMP report/query information.
Note that if both an IGMP report and IGMP query is received at the same port, information about both are displayed in the tooltip.
Since the learning status for multicast groups changes over time, click the "Update" button to update the display.
When a multicast group has been learned by an IGMP report, the IP address of the multicast group is displayed in the "Multicast Group" select box.
Traffic being sent to learned multicast groups is only forwarded to IGMP report receiving ports.
Unknown multicast groups are not displayed in the "Multicast Group" select box.
If a ProAV profile is specified, unknown multicast group traffic is discarded.
Please change the setting, if you want to flood an unknown multicast group.
If a problem that prevents receiving multicast traffic occurs, check whether the port indicator where the receiving terminal is connected is illuminated orange (which indicates it is an IGMP report receiving port).
If the connection port indicator is not orange, the receiving terminal might be connected to a port with a different profile. Check the profile setting for the port where it is connected.
If that does not solve the problem, try disabling IGMP snooping, but determine whether the bandwidth is sufficient before disabling IGMP snooping.
