Ok, I found what I think I'm looking for. I'm networking to another system via VPIM and it looks like FTP is the preferred method of adding bulk remote subscribers into MN.
So my question now is regarding this icftp password. I have no idea what this would be set to. I see in general parameters that FTP is not enabled. I also found instructions to reset the FTP password, but I don't seem to have the same screens as the below. On my web interface I see a choice for 'icftp configuration' and it's asking for local authentication and password, which are both not populated. When I check in local administrators there's only an SA account and not icftp. I don't have the below.
Start at the Administration menu, and select Basic System Administration > Password Administration > Assign/Change Password.
The system displays the Assign/Change Password page.
Select icftp from the Login menu.
Type the new password in the New Password field.
Type the new password again in the Re-enter New Password field.
Click Save.
The password for the FTP process has now been updated.
Click Return to Main to return to the Administration menu.
