Parameters

Federation is a means by which two organizations can set up a trust relationship that facilitates communication between the two groups. When federation has been established, users in the two organizations can send each other instant messages, subscribe for presence notifications, and otherwise communicate with one another using SIP applications such as Microsoft Lync 2010. Lync Server 2010 allows for three types of federation: 1) direct federation between your organization and another; 2) federation between your organization and a public provider; and, 3) federation between your organization and a third-party hosting provider.

A public provider is an organization that provides Session Initiation Protocol (SIP) communication services for the general public. When you establish a federation relationship with a public provider, you effectively establish federation with any user who has an account hosted by that provider. For example, if you federate with MSN, then your users will be able to exchange instant messages and presence information with anyone who has an MSN instant messaging account.

In order to federate with a public provider you need to create and enable a new public provider. (In addition, the public provider will need to create a federation relationship with you.) When you create a public provider, you have the option of either enabling or disabling that federation relationship. If a public provider is enabled, then users in your organization will be able to exchange instant messages and presence information with people who have accounts with the public provider. If a public provider is disabled, then your ability to communicate with people who have accounts with the public provider will be suspended, and will remain suspended until the provider has been re-enabled. If you need to temporarily suspend a provider relationship you can do so by using the Disable-CsPublicProvider cmdlet. If you prefer to delete that provider altogether, use the Remove-CsPublicProvider cmdlet.

Who can run this cmdlet: By default, members of the following groups are authorized to run the Disable-CsPublicProvider cmdlet locally: RTCUniversalServerAdmins. To return a list of all the role-based access control (RBAC) roles this cmdlet has been assigned to (including any custom RBAC roles you have created yourself), run the following command from the Windows PowerShell prompt:

Get-CsAdminRole | Where-Object {$_.Cmdlets –match "Disable-CsPublicProvider"}

Microsoft.Rtc.Management.WritableConfig.Settings.Edge.DisplayPublicProvider object. Disable-CsPublicProvider accepts pipelined instances of the public provider object.

None. Instead, the cmdlet disables instances of the Microsoft.Rtc.Management.WritableConfig.Settings.Edge.DisplayPublicProvider object.

-------------------------- Example 1 ------------------------

	Copy Code
Disable-CsPublicProvider -Identity "MSN"

The preceding command disables the public provider with the Identity MSN. This command will return an error if MSN is already disabled.

-------------------------- Example 2 ------------------------

	Copy Code
Get-CsPublicProvider | Where-Object {$_.Enabled -eq $True} | Disable-CsPublicProvider

Example 2 disables all the public providers that are currently enabled. To do this, the command first uses Get-CsPublicProvider to return a collection of all the public providers currently in use in the organization. This collection is piped to the Where-Object cmdlet, which picks out only those providers where the Enabled property is equal to True. In turn, this filtered collection is piped to Disable-CsPublicProvider, which disables each provider in the collection.

-------------------------- Example 3 ------------------------

	Copy Code
Get-CsPublicProvider | Where-Object {$_.VerificationLevel -ne "AlwaysVerifiable" -and $_.Enabled -eq $True} | Disable-CsPublicProvider

The command shown in Example 3 disables all the public providers that are current enabled and that have a verification level set to AlwaysVerifiable. To accomplish this task, the command first calls Get-CsPublicProvider to return a collection of all the public providers currently in use in the organization. This collection is then piped to Where-Object, which selects the providers that meet two criteria: 1) the VerificationLevel property is equal to AlwaysVerifiable; and, 2) the Enabled property is equal to True. (The -and operator tells Where-Object that objects must meet all the specified criteria in order to be selected.) The filtered collection is then piped to Disable-CsPublicProvider, which disables each provider in that collection.
