RMON Alarm

This page provides an overview of RMON Alarm entries. Each page shows up to 99 entries from the Alarm 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 Alarm table. The first displayed will be the one with the lowest ID found in the Alarm table.
The "Start from Control Index" allows the user to select the starting point in the Alarm table. Clicking the button will update
the displayed table starting from that or the next closest Alarm table match. The form will use the last entry of the
currently displayed entries 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 ROMON Alarm Overview in the web interface:

Click Monitor / Security / Switch / RMON / Alarm

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.
