Managed Switch Port Mapping Tool Version 2.41 was released on January 14, 2015.
This is an important upgrade if you use this software with Cisco Switches. There are two changes you need to be aware of: First, we improved VLAN reporting for unused ports on Cisco switches. Secondly, we added a new optional Voice VLAN column that currently supports Cisco switches only - because this column is new you will have to go into Settings and Tools/Column Order and Visibility Editor to add the column and to put the columns back to your personal preference - we had to reset the order to add the new column. Changes were made to better support Enterasys switches.
Please use Help/Check for Update or download from SwitchPortMapper.com and install over your current 2.x. The USB version patch will be ready very soon.
