You can unassign a user from a RADIUS profile if you want to assign the user to another profile. For example, you might need to assign the user to a profile with a different value for the Framed-Pool attribute (allowed IP addresses).
In the Security Console, click RADIUS > RADIUS Profiles > Manage Existing.
Click the profile that you want.
From the context menu, click Associated Users.
Click the user that you want to unassign from the profile.
From the context menu, click Unassign User.
To quickly unassign multiple users from a profile, select the checkboxes next to the users, and click Unassign.
