Description

The Set-NetworkController cmdlet sets network controller application settings. You can modify the following settings:

• Client authentication mode.
• Client security group. If the client authentication mode is Kerberos, you must specify a client security group.
• Client certificate thumbprints. If the client authentication mode is x509, you must specify certificate thumbprints.
• The IP address that network controller uses for representational state transfer (REST) communication.
• Secure Sockets Layer (SSL) certificate that network controller uses for encrypting the communication between the REST clients and the network controller, as well as to secure communication with southbound clients.

Examples

Example 1: Change the authentication mode for clients

PS C:\> Set-NetworkController -ClientAuthentication Kerberos -ClientSecurityGroup "Contoso\RestClients" -PassThru
Node                            : {Node01, Node02, Node03}
ClientAuthentication            : Kerberos
ClientCertificateThumbprint     :
ClientSecurityGroup             : Contoso\RestClients
ServerCertificate                  : [Subject]
                                   CN=NCEncryption

                                  [Issuer]
                                    CN=Contoso

                                  [Serial Number]
                                    1C00000003786A607D6EFB733F000000000003

                                  [Not Before]
                                    2/11/2015 6:18:21 AM

                                  [Not After]
                                    2/10/2017 6:18:21 AM

                                  [Thumbprint]
                                    D4FDE4F607849083C590466334D66037C0E38001

RestIPAddress                   : 10.0.0.1/24
Version                         : 10.0.0

This command changes the authentication mechanism between REST clients and network controller to Kerberos. In order to change the authentication mode to Kerberos, you must also specify the ClientSecurityGroup parameter.

Example 2: Change the REST IP address

PS C:\> Set-NetworkController -RestIPAddress 10.0.0.1/24

This command changes the REST IP address to 10.0.0.1. This command requires that the subnet mask be specified in the IP address.

Parameters

-CertificateThumbprint

Specifies the digital public key X.509 certificate of a user account that has permission to perform this action. Specify the certificate thumbprint of the certificate. Specify this parameter only if you run this cmdlet on a computer that is not part of the network controller cluster.

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ClientAuthentication

Specifies the type of authentication that network controller uses to communicate with REST clients. The acceptable values for this parameter are:

• Kerberos
• X509
• None

If the clients and network controller computers are domain joined, you should specify Kerberos authentication. Otherwise, specify X509 authentication. We do not recommend a value of None for production environments.

Type:	ClientAuthentication
Accepted values:	None, Kerberos, X509
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ClientCertificateThumbprint

Specifies an array of thumbprints of the certificates of REST clients that can communicate with the network controller. Specify this parameter only if the value of the ClientAuthentication parameter is X509.

Type:	String[]
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ClientSecurityGroup

Specifies the security group that contains the name of the REST clients that can communicate with the network controller. Specify this parameter only if the value of the ClientAuthentication parameter is Kerberos.

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
