Parameters

Parameter Required Type Description

Identity

Required

Xds Identity

Unique identifier for the client version policy rule to be modified. The Identity of a client version rule consists of the scope where the rule has been configured plus a globally unique identifier (GUID). That means that a rule will have an Identity similar to this: site:Redmond/1987d3c2-4544-489d-bbe3-59f79f530a83.

Instance

Optional

Rule object

Allows you to pass a reference to an object to the cmdlet rather than set individual parameter values.

Action

Optional

PS List Modifier

Action to be taken any time the rule is triggered (that is, any time someone attempts to log on by using the specified software). Valid values are:

Allow. The user will be allowed to log on.

AllowWithUrl. The user will be allowed to log on, and a message will be displayed pointing him or her to a URL where the latest version of Lync can be downloaded and installed.

AllowAndUpgrade. The user will be allowed to log on, and his or her copy of Communicator will automatically be upgraded to the latest version of Lync.

Block. The user will not be allowed to log on.

BlockWithUrl. The user will not be allowed to log on, but a message will be displayed pointing him or her to a URL where the latest version of Lync can be downloaded and installed.

BlockAndUpgrade. The user will not be allowed to log on, but his or her copy of Communicator will automatically be upgraded to the latest version of Lync. The user can then try to log on by using the new client application.

ActionUrl

Optional

String

URL where users can download the latest version of Lync. This property is required if the Action is set to BlockWithUrl or AllowWithUrl.

BuildNumber

Optional

Integer

Build number of the software. For example, if your copy of Communicator is version 2.0.6362.111, then the BuildNumber is 6362. Build numbers represent internal versions of the software during the development process, and help to ensure that you are using the final release version as opposed to a pre-release version.

CompareOp

Optional

PS List Modifier

Comparison operator used to determine if the client software attempting to log on was released before, after, or at the same time as the version specified in the rule. Valid values are:

EQL (equal to)

NEQ (not equal to)

GTR (greater than)

GEQ (greater than or equal to)

LSS (less than)

LEQ (less than or equal to)

Description

Optional

String

Enables administrators to provide additional information about the client version rule. For example, the Description might include information about who to contact if you believe the rule should be changed.

Enabled

Optional

Boolean

Indicates whether or not the client version rule is to be used. If the Enabled property is set to False the rule will be ignored any time a user attempts to log on with the specified software. The default value is True.

MajorVersion

Optional

Integer

Major version of the software. For example, if your copy of Communicator is version 2.0.6362.111, then the MajorVersion is 2. Major versions equate to primary releases of the software.

MinorVersion

Optional

Integer

Minor version of the software. For example, if your copy of Communicator is version 2.0.6362.111, then the MinorVersion is 0. Minor versions equate to interim releases of the software.

Priority

Optional

Integer

Relative priority of the rule. Rules are processed in priority order, with the rule with priority 0 being processed first, the rule with priority 1 being processed second, and so on. If you assign a priority already in use, the new rule will use that priority and other rules will be renumbered accordingly.

QfeNumber

Optional

Integer

Quick fix engineering number of the software. For example, if your copy of Communicator is version 2.0.6362.111, then the QfeNumber is 111. QFE numbers represent planned updates to an application that are made available after the software’s official release.

UserAgent

Optional

String

Designator used to identify the software client. For example, OC is the user agent designation for Communicator. The Get-CsClientVersionConfiguration cmdlet provides corresponding friendly names for each user agent designation.

Force

Optional

Switch Parameter

Suppresses the display of any non-fatal error message that might occur when running the command.

WhatIf

Optional

Switch Parameter

Describes what would happen if you executed the command without actually executing the command.

Confirm

Optional

Switch Parameter

Prompts you for confirmation before executing the command.

Detailed Description

Client version rules are used to determine which client applications are allowed to log on to Microsoft Lync Server 2010. When a user attempts to log on to Lync Server 2010, his or her client application sends a SIP header to the server; this header includes detailed information about the application itself, including the software’s major version, minor version, and build number. The version information is then checked against a collection of client version rules to see if any rules apply to that particular application. For example, suppose a user attempts to log on by using Microsoft Office Communicator 2007 R2. Before the user can log on to Lync Server 2010, the system will check to see if there is a client version rule that applies to Office Communicator 2007 R2. If a rule exists, Lync Server 2010 will then take the action specified by the rule. That action must be one of the following:

Allow. The user will be allowed to log on.

AllowAndUpgrade. The user will be allowed to log on, and his or her copy of Communicator 2007 R2 will automatically be upgraded to the latest version of Lync. Upgrades are carried out using either Microsoft Update or Windows Server Update Services, depending on how you have configured your system.

AllowWithUrl. The user will be allowed to log on, and a message will be displayed pointing the user to a URL where the latest version of Lync can be downloaded and installed. The URL must point to a website that you have created yourself; no such site is created for you when you install Lync Server.

Block. The user will not be allowed to log on.

BlockAndUpgrade. The user will not be allowed to log on, but his or her copy of Communicator 2007 R2 will automatically be upgraded to the latest version of Lync. The user can then try to log on by using the new client application. Upgrades are carried out using either Microsoft Update or Windows Server Update Services, depending on how you have configured your system.

BlockWithUrl. The user will not be allowed to log on, but a message will be displayed pointing him or her to a URL where the latest version of Lync can be downloaded and installed. The URL must point to a website that you have created yourself; no such site is created for you when you install Lync Server.

Client version rules are collected in client version policies; these policies that can be configured at the global scope, the site scope, the service scope (Registrar service), or the per-user scope. The Set-CsClientVersionPolicyRule cmdlet provides a way for you to modify the properties of an existing client version rule.

It’s important to note that client version policies do not apply to federated users; instead, federated users are bound by the client version policies used in their own organization. For example, suppose a federated user uses client A, a client allowed by the federated organization. As long as the federated organization allows the use of client A, this user will be able to communicate with your organization using that client. This will be true even if your client version policy blocks the use of client A. Client version policies enforced in your organization do not override the client version policies used in a federated organization.

Who can run this cmdlet: By default, members of the following groups are authorized to run the Set-CsClientVersionPolicyRule 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 "Set-CsClientVersionPolicyRule"}

Input Types

Microsoft.Rtc.Management.WritableConfig.Policy.ClientVersion.Rule object. Set-CsClientVersionPolicyRule accepts pipelined instances of the client version rule object.

Return Types

None. Instead, Set-CsClientVersionPolicyRule modifies instances of the Microsoft.Rtc.Management.WritableConfig.Policy.ClientVersion.Rule object.

Example

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

Copy Code
Set-CsClientVersionPolicyRule -Identity site:Redmond/74ba9211-8610-42f9-91ba-846cdee98820 -Enabled $False

The command shown in Example 1 disables the client version policy rule that has the Identity site:Redmond/74ba9211-8610-42f9-91ba-846cdee98820. To disable the rule, the command includes the Enabled parameter and the parameter value $False.

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

Copy Code
Get-CsClientVersionPolicyRule -Filter "site:Redmond*" | Set-CsClientVersionPolicyRule -Description "Client policy rules for Redmond"
G

Example 2 adds a generic description to all the client version policy rules assigned to the Redmond site. To do this, the command first calls Get-CsClientVersionPolicyRule along with the Filter parameter; the filter value "site:Redmond*" limits the returned data to policy rules assigned to the Redmond site. This collection is then piped to the Set-CsClientVersionPolicyRule cmdlet, which assigns the Description "Client policy rules for Redmond" to each item in that collection.

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

Copy Code
Get-CsClientVersionPolicyRule | Where-Object {$_.UserAgent -eq "UCCP"} | Set-CsClientVersionPolicyRule -Action "Block"

The preceding command blocks the use of Unified Communications Client Platform (UCCP) clients for any client version policy rule that references UCCP as the user agent. To carry out this task, the command first calls Get-CsClientVersionPolicyRule to retrieve a collection of all the client policy rules currently in use. This collection is then piped to the Where-Object cmdlet, which picks out only those rules where the UserAgent property is equal to (-eq) UCCP. This filtered collection is then piped to the Set-CsClientVersionPolicyRule cmdlet, which takes each item in the collection and sets the Action property to Block.
