Switch Port Mapper Tip

Applies to all v1.x through 2.34:

If you use the menu item Settings and Tools/Column Order and Visibility Editor to add/remove columns or change where they appear, be sure to keep the Interface Index (ifIndex) column visible.

In other words, if you remove the ifIndex column some other columns may not show data you expect to see. The next release will not allow you to remove the ifIndex column.
