Setting up autodiscovery for Mac systems

APPLIES TO:
  • Parallels Mac Management

Symptoms

I have installed PMM on my SCCM. I need to start adding my Mac systems to the Management Console (for management or simple discovery).

  • Mac systems are not discovered on my network.
  • My Mac systems are discovered but show IP addresses instead of names
  • What are the requirements to set up the autodiscovery?

Cause

Both software solutions (PMM and SCCM) can have a misconfiguration which will result in autodiscovery not working.

Resolution

Autodiscovery works by utilizing Nmap port scanner.

There are few places where configuration is required to make sure that everything is set up properly.

  • First of all, make sure that autodiscovery itself is enabled:

    Enable

  • Next we need to setup places where it will look for Macs in form of IP boundaries (subnets). We will configure allowed IP address boundaries:

    Boundaries

    Specify the subnet where Macs are located via Network and Subnet mask fields. Additionally, make sure that Mac Boundary Group (in Boundary Groups) contains your boudary:

    Groups

  • Back in Discovery Methods, we need to set up actual target address range for Nmap to scan:

    Right-click Parallels Network Discovery and select Properties:

    Props

    It is not recommended to change TCP ports unless you know what this field does. Nmap timing policy will control how aggressive Nmap is with its requests. The more aggressive it is, the more request it will send in the same period of time.

  • If you plan to enroll discovered Mac aswell, you need to specify the account name (and password):

    Enroll

  • Now, configure Nmap. It is a good idea to put the same settings as you did when configuring boundaries:

    Nmap

  • Almost done. Now we need to tell Nmap when to scan for Macs. We will configure Schedule on the tab with the same name:

    Schedule

Now after the procedure runs, you can check if your Macs were added under devices:

Devices

If something is still not working right, you can find additional information on actual actions performed and their outcomes in discovery process logs. pma_discovery log is located in C:\Windows\Logs\pma_discovery:

Log

o Note: in Parallels Mac Management 4.5, user account settings have been moved to the new Parallels Mac Client Push Installation Properties dialog, which is now used for both (AD and Network) discovery methods. For more information, please see the Configuring Parallels Mac Client Push Installation Properties section in the Parallels Mac Management for Microsoft SCCM Administrator’s Guide.
