Example: Creating a Table from ifTable

The ifTable if the IF-MIB shows the interfaces on a device. To create an on-demand table, you will need to review the MIB to find the table's definition.

Find the table's name (ifTable in the excerpt below), and the names for the columns of the table (everything between the { ... } in the ifEntry below). Paste those into the fields on this page, and you'll get the definition suitable for entry into the custom SNMP probe.
