IGMP Snooping IPv4 SFM Information
Entries in the IGMP SFM Information table are shown on this page. The IGMP SFM (Source-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. Different source addresses belong to the same
group are treated as single entry.
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, this page shows 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
SSM Information Table. Clicking
Refresh
the 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
>>
button 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
" displays in the displayed table. Use the
|<<
button to start
over.
