Collecting table information
SNMP tables are collections of different types of objects. Picture the SNMP table as a spreadsheet. Each row contains fields of data related to an object. Access to the SNMP MIB table is similar to reading the spreadsheet row by row.
SNMP works in the following way: SNMP Extension requests the values of all or some objects from the first line in the SNMP MIB table. After receiving a reply, it displays the values in the table and requests information for the next line. SNMP Extension continues to collect information row by row until it reaches the end of the table. This process is called traversing the table in SNMP terminology.
To receive table information from an agent, select the table tree item in the SNMP Agent Request area, and double click on the table you wish to view.

Tables are created and modified using the Forms Designer in the MIB Editor. List requests are created and modified using the MIB Editor.
Read Values Display
SNMP Extension will read the table and display the values of the table objects line by line. Tables can contain more than one writable object. Writable objects display [RW] in the Access column of the display. Read-only objects show [RO] in the Access column.
