IGMP SFM Information Table
Entries in the IGMP SFM Information Table are shown on this page. The IGMP SFM
(Souce-Filtered Multicast) Information Table also contains the SSM (Source-Specific
Multicast) information. This table is sorted first by VLAN ID, then by group, and then
by Port No. Diffrent source add resses belong to the same group are treated as
single entry.
Navigating the IGMP SFM Information Table
Each page shows up to 99 entries from the IGMP SFM Information table, default
being 20, selected through the "entries per page" input field. When first visited, the
web page will show the first 20 entries from the beginning of the IGMP SFM
Information Table.
The "Start from VLAN", and "group" input fields allow the user to select the starting
point in the IGMP SFM Information Table. Clicking the Refresh button will update the
displayed table starting from that or the closest next IGMP SFM Information Table
match. In addition, the two input fields will - upon a Refresh button click - assume the
value of the first displayed entry, allowing for continuous refresh with the same start
address.
The >> will use the last entry of the currently displayed table as a basis for the next
lookup. When the end is reached the text "No more entries" is shown in the
displayed table. Use the |<< button to start over.
