3-5.4.1.1 Statistics
This page displays an overview of RMON Statistics entries. Each page shows up to 99 entries from the
Statistics 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 Statistics table. The first displayed will be
the one with the lowest ID found in the Statistics table.
The "Start from Control Index" lets you select the starting point in the Statistics table. Clicking the Refresh
button will update the displayed table starting from that or the next closest Statistics table match.
Clicking the Next entry button will use the last entry of the currently displayed entry 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.
