Description

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 by using SIP applications such as Skype for Business. Skype for Business Server 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.

Setting up direct federation with another organization involves several tasks. To begin with, you must enable your Access Edge servers to allow federation. In addition, the other organization must enable federation with you; federation cannot be established unless both parties agree to the relationship.

To set up a federated relationship you might also need to manage two federation-related lists: the allowed list and the blocked list. The allowed list (required if EnablePartnerDiscovery has been disabled) represents the organizations you have chosen to federate with. If a domain appears on the allowed list then (depending on your configuration settings) your users will be able to exchange instant messages and presence information with users who have accounts in that federated domain. Conversely, the blocked list represents domains that users are expressly forbidden from federating with; for example, messages sent from a blocked domain will automatically be rejected by Skype for Business Server.

The Get-CsAllowedDomain cmdlet provides a way for you to return information about all the domains on the allowed domains list.

Examples

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

Get-CsAllowedDomain

The command shown in Example 1 returns a collection of all the domains included in the list of domains approved for federation. Calling the Get-CsAllowedDomain cmdlet without any additional parameters always returns the complete collection of approved domains.

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

Get-CsAllowedDomain -Identity fabrikam.com

Example 2 returns information about the allowed domain with the Identity "fabrikam.com". Because identities must be unique, this command will never return more than one item.

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

Get-CsAllowedDomain -Filter *fabrikam*

The command shown in Example 3 returns a collection of all the allowed domains that have the string value "fabrikam" anywhere in their Identity. To do this, the command uses the Filter parameter and the filter value "*fabrikam*". This filter value tells the Get-CsAllowedDomain cmdlet to return only those domains where the Identity (the only property you can filter on) includes the string value "fabrikam". Domains such as fabrikam.com, fabrikam.net, and africa.fabrikam.org will all be returned by this command.

-------------------------- Example 4 --------------------------

Get-CsAllowedDomain | Where-Object {$_.ProxyFqdn -eq $Null}

In Example 4, the Get-CsAllowedDomain cmdlet and the Where-Object cmdlet are used to return a collection of all the domains where no value has been entered for the ProxyFqdn property. To carry out this task, the Get-CsAllowedDomain cmdlet is first called without any additional parameters in order to return a collection of all the allowed domains. This collection is then piped to the Where-Object cmdlet, which selects only those allowed domains where the ProxyFqdn property is equal to a null value; a null value means that no value has been entered for ProxyFqdn. To find all the domains that have a value of some kind configured for the ProxyFqdn property, use this syntax instead: Where-Object {$_.ProxyFqdn -ne $Null}.

-------------------------- Example 5 --------------------------

Get-CsAllowedDomain | Where-Object {$_.MarkForMonitoring -eq $True}

Example 5 returns all the allowed domains that have their health status checked by the Monitoring Server. To do this, the Get-CsAllowedDomain cmdlet is first used to return a collection of all the domains on the allowed domains list. That collection is then piped to the Where-Object cmdlet, which picks out only those domains where the MarkForMonitoring property is equal to True.
