How to Set the PXE Service Point Response for a Specific Network Interface

In Configuration Manager, you set the operating system deployment to respond to a specific set of network addresses by adding the required media access control (MAC) addresses to the BindExcept embedded property list. You must also set the BindPolicy embedded property to 1. This specifies that PXE requests are accepted on specified network address only. For more information about setting BindPolicy, see How to Set the PXE Service Point Response to All Network Interfaces.

To set the response for a specific network interface

  1. Set up a connection to the SMS Provider. For more information, see SMS Provider fundamentals.

  2. Make a connection to the PXE service point resources section of the site control file.

  3. Get the BindExcept embedded property list.

  4. Add the MAC addresses to the BindExcept embedded property list.

  5. Commit the changes to the site control file.

Example

The following example method adds a supplied MAC address to the list of MAC address that are responded to.

For information about calling the sample code, see Calling Configuration Manager Code Snippets.

public void SetNetworkInterface(WqlConnectionManager connection,                                string siteCode,                                string serverName,                                string macAddress){    try    {        //Connect to distribution point instance.                        IResultObject siteRole = connection.GetInstance("SMS_SCI_SysResUse.FileType=2,ItemName=\"[\\\"Display=\\\\\\\\" + serverName + "\\\\\\\"]MSWNET:[\\\"SMS_SITE=" + siteCode + "\\\"]\\\\\\\\" + serverName + "\\\\,SMS Distribution Point\",ItemType=\"System Resource Usage\",SiteCode=" + "\"" + siteCode + "\"");        // Create temporary copy of the embedded properties.        Dictionary<string, IResultObject> embeddedPropertyLists = siteRole.EmbeddedPropertyLists;        // Get current mac addresses.        string[] macAddresses = embeddedPropertyLists["BindExcept"]["Values"].StringArrayValue;        //Convert to list.        List<string> addressList = new List<string>();        foreach (string address in macAddresses)        {            addressList.Add(address);        }        // Add the new mac address to the list.        addressList.Add(macAddress);        // Add the new mac address to the list.        embeddedPropertyLists["BindExcept"]["Values"].StringArrayValue = addressList.ToArray();        siteRole.EmbeddedPropertyLists = embeddedPropertyLists;        // Save the settings.         siteRole.Put();    }    catch (SmsException ex)    {        Console.WriteLine();        Console.WriteLine("Failed. Error: " + ex.InnerException.Message);    }}

The example method has the following parameters:

Parameter Type Description
connection - Managed: WqlConnectionManager A valid connection to the SMS Provider.
serverName - Managed: String The Configuration Manager server.
siteCode - Managed: String The Configuration Manager site code.
macAddress - Managed: String The MAC address to be added in the following format:

00:11:22:33:44:55
