According to the help file ,should this be possible.
Select the Pattern radio button and enter the username, MAC address, or hostname that the end-system must match for this mapping. Or, select the Group radio button and select a user group or end-system group from the drop-down list. If you enter a MAC address, you can use a colon (:) or a dash (-) as an address delimiter, but not a period (.).
The only groups I can select are End-System Groups.
How can I select an user groups ?
