Assign the System Center Virtual Machine Manager (VMM) that will be used by 
Lab Management and the network location that will be used for virtual machines. 
Optionally create network isolated environments.

    TfsConfig lab /settings  
                      [[/scvmmservername:]
                      [/networklocation:]
                       [/ipblock:
                      [/dnssuffix:]
                      [/labUrl:]
                       [/noprompt]]
                      [/list]

    The /settings options specifies the System Center Virtual Machine 
    Manager (VMM) that will be used by Lab Management and the network 
    location that will be used for virtual machines. Other options 
    enable you to configure network isolation. Network isolation 
    allows you to run multiple copies of a lab environment at the same 
    time without causing network conflicts, such as conflicts in 
    computer names and Domain Name System (DNS) registration. 
    
    Use the following options with the /settings option:
        /scvmmServerName:
            Optional. Specifies the name of the System Center Virtual 
            Machine Manager (VMM) server that will be used by Team 
            Foundation Server (TFS) to manage the virtual machines. 
            To enable TFS to communicate with VMM, you must add the 
            account under which TFS is running to the Administrator 
            role in VMM.
        /networkLocation: 
            Optional. Specifies a network location that is available on 
            all the hosts in your lab network. Virtual machines that are
            provisioned by Lab Management will be connected to the 
            specified network location during deployment. You can find
            the available network locations on a host by using 
            VMM Administrator Console. 
        To set up Lab Management from the command line, both the 
        /scvmmServerName and the /networkLocation options must be specified.
        You can specify the two options on the same command line or on
        separate command lines.
        
        /ipBlock:
            Optional. Specifies the range of IP addresses to be assigned to
            the virtual machines in an environment when an isolated network
            is created. Because the IP addresses are used only for internal
            routing among virtual machines and are not exposed beyond the
            boundaries of an environment, you can specify any IP range that
            is not used within your public network. 
        /dnsSuffix:< dns suffix for network isolation>
            Optional. Specifies the DNS suffix that will be used to register
            the names of virtual machines on the isolated network for the
            virtual environment. To confirm that the suffix is configured
            correctly in the DNS hierarchy, contact your 
            network administrator.
        To configure network isolation from the command line, both the
        /ipBlock and the /dnsSuffix options must be specified. You can 
        specify the two options on the same command line or on separate
        command lines.

        /labUrl:
            Optional. Specifies the Team Foundation Server url that will 
            be used by build agents which are auto-configured by lab. It is 
            recommended to use FQDN in this url as otherwise it may lead to 
            communication problems when lab machine is not on the same domain
            as Team Foundation Server. The default value for this is equal to 
            the 'NotificationUrl' converted to an FQDN format. 
        To restore the default value for labUrl from the command line, empty
        value for labUrl should be specified. To override the labUrl for any 
        team project collection, specify the collectionName parameter.
