After you set the IGMP Snooping function, the switch can display the IGMP Snooping Group

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.

Parameter description:
Navigating the IGMP Group Table
Each page shows up to 99 entries from the IGMP Group table, default is 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 Group Table.
The "Start from
VLAN
" and "group" input fields allow the user to select the starting point in the IGMP
Group Table. Clicking the button will update the displayed table starting from that or the closest next
IGMP Group Table match. In addition, the two input fields will—upon a button click—assume the
value of the first displayed entry, allowing for continuous refresh with the same start address.
The switch 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.
