RMON History Overview
This page provides an overview of RMON History entries. Each page shows up to 99 entries from the History 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 History table. The first displayed will be the one with the lowest History Index and Sample Index
found in the History table. The "Start from History Index and Sample Index" allows the user to select the starting point in
the History table. Clicking the button will update the displayed table starting from that or the next closest History table
match. This 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.
To display the RMON History Configuration in the web interface:
Click Monitor / Security / Switch / RMON / History
Enter a Start from Control Index and the number of entries to be displayed per page.
Check the Auto-Refresh check box to have the page automatically refresh every 3 seconds.
