When fallback starts, the client receives a list of all software update points in its current boundary group. Assign software update points to a boundary group so that clients can find and use them. When an internet machine connects to the VPN, it will continue scanning against the CMG software update point over the internet. Click on references tab, check Use this Boundary group for site assignment. If a device is in more than one boundary group, the following behaviors apply for these settings: This setting is enabled by default. All combined boundaries within a single boundary group are assumed to have a high-speed connection between them. When a device runs a task sequence and needs to acquire content, it uses boundary group behaviors similar to the Configuration Manager client. Then configure boundary groups at individual primary sites. Relationships are configured on a boundary group properties Relationships tab. Find an assigned site: Boundary groups enable clients to find a primary site for client assignment. If no content was available, the setup process fell back to download content from the management point. In version 2002, when you expand a stand-alone primary site to add a central administration site (CAS), the subnet exclusion list reverts to the default. When the client expands its search, the site provides any boundary groups configured for less than 120 minutes. As the term implies, clients cache the name of their current boundary groups. Clients use local management points first (locality 3), remote second (locality 2), then fallback (locality 1). Overlapping occurs when a client's location maps to multiple boundary groups. In previous versions of Configuration Manager, during this process the management point only returned distribution points in the client's current boundary group. It adds servers to the available pool of software update points that are in it's current and any neighbor boundary groups configured for 120 minutes or less. This group contains distribution points DP_C1 and DP_C2. For more information, see Configure fallback behavior. This group is named Default-Site-Boundary-Group
. Configure this behavior using the following settings on the Distribution Points page of the task sequence deployment: When no local distribution point is available, use a remote distribution point: For this deployment, the task sequence can fall back to distribution points in a neighbor boundary group. United States (English) Use the percent sign (%) as a wildcard character. Client roaming means it changes its network locations. It searches each distribution point for two minutes, and then switches to the next distribution point in the boundary group. Find certain site system roles they can use: Associate a boundary group with certain site system roles. By default, the management point prioritizes peer cache sources at the top of the list of content locations. left join vSMS_Boundary as sys4 on sys3.BoundaryID=sys4.BoundaryID where sys1.GroupID=sys3.GroupID for XML path(”)) as ‘Boundary’, sys1.ModifiedOn, sys1.ModifiedBy from vSMS_BoundaryGroup as sys1. Enable this option and clients only share content within the subnet at the remote office location, instead of risking sharing content between locations. By default, Configuration Manager creates a default site boundary group at each site. This search of additional groups is called fallback. For more information, see Enable use of preferred management points. Configure the second neighbor group (BG_C) to be used after 20 minutes. Append additional subnets to the list, and then set the new value. These locations include devices that you want to manage. For client content requests, Configuration Manager includes only distribution points that have the requested content in the list of site systems returned. When a client can't find an available site system, it begins to search locations from neighbor boundary groups. Site assignment, used to control which sites clients are assigned to. When the network location of the client falls within a boundary group that is enabled for site assignment, or the hierarchy is configured for a fallback site, the client is automatically assigned to that site without your having to specify a site code. After assigning to a site, a client doesn't change its site assignment when it changes its network location. After failing to reach its original server for two hours, the client then uses a shorter cycle to establish a connection to a new software update point. Instead, each site system associated with a boundary group is treated the same. On the top-level site server, set or read the SubnetExclusionList embedded property for the SMS_HIERARCHY_MANAGER component in the SMS_SCI_Component class. This happens for one of two reasons: You add the same boundary to multiple boundary groups. Boundary group caching was introduced with the first version of System Center Configuration Manager (ConfigMgr) Current Branch (CB): version 1511. Clients that are on the internet or configured as internet-only clients don't use boundary information. The link is called a relationship. We can, therefore, associate clients with the localised roles and we can add in DPs, SUPs (since ConfigMgr 1702), preferred MPs and state migration points in as site systems defined in our boundary groups. SCCM, best practices for Boundaries, Boundary Groups, Devices and Device Collections. By default, Configuration Manager includes the Teredo subnet in this list. I created boundary groups with IP range for the machines that are in the secondary sites. This behavior might not be for the site you want the client to join. 1.Open SCCM console,go to client settings, edit default client settings,hardware inventory,set classes,add,choose the wmi namespace and add,once the boundary group cache added,uncheck it from default settings and click ok. For more information,how to add custom inventory,you can refer guide here Change the values for the explicit link to a default site boundary group. If that process fails, it then fails over to a distribution point in a neighbor boundary group with a larger failover time. If a client is in a boundary group that with no assigned management point, the site gives the client the entire list of management points. Boundary groups, in ConfigMgr, allow us to associate our network locations with site system roles. For more information on how to configure these settings, see Configure a boundary group. When a client receives five errors in 10 minutes and fails to communicate with a management point in its current boundary group, it tries to contact a management point in a neighbor or the site default boundary group. Although each boundary group supports both site assignment and site system reference, create a separate set of boundary groups to use only for site assignment. Starting in version 2002, depending on the configuration of your network, you can exclude certain subnets for matching. When ccmsetup contacts the management point to locate the necessary content, the management point returns distribution points based on boundary group configuration. To add the site system servers, click Add and select the Site System Server. Then configure relationships from that boundary group to the other two boundary groups: Configure distribution points for the first neighbor group (BG_B) to be used after 10 minutes. This period is 130 minutes of total time after the client first failed to reach its last known-good software update point. For clients not in a boundary associated with any boundary group: to identify valid site system roles, use the default site boundary group from their assigned site. You can configure each boundary group with an assigned site for clients. For example, if the task sequence fails to acquire content from a distribution point in its current boundary group, it immediately tries a distribution point in a neighbor boundary group with the shortest failover time. The Locality attribute identifies one of the following states: 1: The specified management point is only in the site default boundary group for fallback. You can link each boundary group to one or more additional boundary groups. You must Assign boundaries to boundary groups before using the boundary group. There was no option to fall back to distribution points in other boundary groups that might have the necessary content. You can allow intranet devices to scan against a CMG software update point in the following scenarios: Configure fallback relationships for management points between boundary groups. Boundaries in Configuration Manager define network locations on your intranet. Import your subnet exclusion list as a comma-separated subnet string. To use this new behavior, make sure to update clients to the latest version. When you configure a relationship, you define a link to a neighbor boundary group. To prevent problems when clients can't find an available site system in their current boundary group, define the relationship between boundary groups for fallback behavior. It then continues to search for content from a distribution point in its combined pool of servers. The rest of the pre-requisite files and other … Fallback lets a client expand its search to additional boundary groups to find an available site system. This configuration helps associate clients to site system servers like distribution points that are located near the clients on the network. How to Create VPN Boundary Let’s learn how to create VPN boundaries in this section: 4.6 (19) Beginning with SCCM 2006, you can now create a new boundary type. This behavior increases the pool of available site systems. Fallback for software update points is configured like other site system roles, but has the following caveats: When you install new clients, they select a software update point from those servers associated with the boundary groups you configure. After 10 minutes, Configuration Manager adds the software update points from boundary group A to the pool of available servers. However, the client still tries to reach its original software update point for 120 minutes. A boundary group can have more than one relationship. If you do use a secondary site in a Site Assignment Boundary Group, then client push will be initiated by the secondary site server and the initial CCMSETUP files will also come from that secondary site. Clients that already have a software update point continue to use it until it can't be reached. Its initial behavior depends upon the command-line parameters you use to install the client: For more information on these ccmsetup parameters, see Client installation parameters and properties. Use this boundary group for site assignment GE3401 Boundary When a boundary is a member of multiple boundary groups that have different assigned sites, clients randomly select one of the sites. When you create an explicit link from the current boundary group to the default site boundary group, and define a fallback time that is less than the fallback time for a link to a neighbor boundary group, clients begin searching source locations from the default site boundary group before including the neighbor group. This behavior replaces the previous behavior where clients select a software update point randomly from a list of the servers that share the client's forest. It uses the failover times for prioritizing the neighbor boundary groups. An upgraded SCCM client now sends a location request which includes information about its network configuration. For more information, see Understand how clients find site resources and services. Applies to: Configuration Manager (current branch). Use boundary groups in Configuration Manager to logically organize related network locations to make it easier to manage your infrastructure. In the Devices node or when you show the members of a Device Collection, add the new Boundary Group(s) column to the list view. You no longer explicitly configure a distribution point to be used for fallback. 3: The specified management point is in the local or current boundary group. Configuration Manager boundaries are locations on your network that contain devices that you want to manage. Because of this change, the References tab of the boundary group properties no longer supports the configuration of Fast or Slow. When a boundary is added to multiple boundary groups that have different assigned sites, clients will aimlessly select one of the sites. The following are the supported boundary types: 1. The ConfigMgr Boundaries define network locations on your intranet. For a boundary that's a member of two different boundary groups with different site assignments, clients randomly select a site to join. Then select a site from the Assigned site dropdown list. For more information on how to configure site assignment, see the following procedures: When a client requests the location of a distribution point, Configuration Manager sends the client a list of site systems. If the client hasn't found content after a total of 120 minutes, it falls back to include the default site boundary group as part of its continued search. You may want to use the SCCM … Boundary groups include the following additional settings to give you more control over content distribution in your environment: Allow peer downloads in this boundary group, During peer downloads, only use peers within the same subnet, Prefer distribution points over peers with the same subnet, Prefer cloud distribution points over distribution points. To find a site system server that can provide a service, including: The state migration point doesn't use fallback relationships. When a client searches for a content source location, it tries to access each distribution point for two minutes before then trying another distribution point. Then the default site boundary group becomes a neighbor boundary group. This setting is dependent upon the preceding option. The client's assigned site doesn't change. SCCM SQL Query … This group contains distribution points DP_B1 and DP_B2. Microsoft official released Preferred Management points in SCCM 2012 R2 SP1 or SCCM 2012 SP2 version. When a client is a member of more than one boundary group, it defines its current boundary group as a union of all its boundary groups. Two clients may be in the same boundary group because they're connected through VPN, but in vastly different locations that are inappropriate for peer sharing of content. This information is site data and only available on primary sites. For more information, see Fallback. In addition to boundary groups you explicitly configure, each boundary group has an implied link to the default site boundary group. With this new setting, the list of content sources that the management point provides to clients only includes peer sources from the same subnet. SMP doesn't use fallback relationships. Check the box for “Use this boundary group for … Client upgrade doesn't honor the boundary group configuration. So choose the Site Code (Primary or Secondary) or select All Due to the real-time nature of task sequence processing, it doesn't wait for the failover time on a neighbor boundary group. Create three boundary groups that don't share boundaries or site system servers: Group BG_A with distribution points DP_A1 and DP_A2, Group BG_B with distribution points DP_B1 and DP_B2, Group BG_C with distribution points DP_C1 and DP_C2. The client falls back to neighbors of any of those original boundary groups. IP address range The boundaries are useless if they are not part of logical grouping called Boundary groups. If you enable this option, the management point only includes in the content location list peer sources that are in the same subnet as the client. During client upgrade, if you don't specify the /MP command-line parameter, the client queries sources such as Active Directory and WMI for any available management point. This configuration is called overlapping boundaries. To enable this boundary group for use by clients for site assignment, select Use this boundary group for site assignment. For more information, see Manually switch clients to a new software update point. Use boundary groups in Configuration Manager to logically organize related network locations (boundaries) to make it easier to manage your infrastructure. Both are well connected to the first group's boundary locations. For each type of supported site system role, configure independent settings for fallback to the neighbor boundary group. A boundary group is basically a group of individual boundaries grouped toghether for one or two purposes. Assign boundaries to boundary groups before using the boundary group. For Content Location, we want clients to get their content locally at their respective location. By configuring the different neighbor groups to be available at different times, you control when specific distribution points are added as a content source location. If the command line doesn't specify the initial management point using the /MP parameter, the new client receives the full list of available management points. We will create 4 Content Boundary groups, add only their AD Site Boundary and assign their local Distribution Point. The default is 120 minutes For a more extensive example, see Example of using boundary groups. By default, Configuration Manager creates a default site boundary group at each site. Avoid overlapping boundaries for automatic site assignment. It's a comma separated string. For its initial bootstrap process, the client uses the first management point it can access. Your management point can determine if the client is on a VPN connection based on this new information. Assign boundaries to boundary groups before using the boundary group. This behavior is also known as automatic site assignment. When the management point is in the current boundary group and either a neighbor or the site default boundary group, the locality is 3. Many of these changes and concepts work together. Otherwise the client won't use delivery optimization. Clients on the boundary group use these servers for policy and content. – Although each SCCM boundary group supports both site assignment and site system reference, create a separate set of boundary groups to use only for site assignment. Boundary group fallback times start when the client first fails to reach its original server. Clients can always use roles associated with their current boundary group. This behavior makes sure that a client always receives a list of management points. Configuration Manager sends this list to a client in response to a content or service location request. When a client roams, it might use a management point from the local site before attempting to use a server from its assigned site. Unveil relevant information by using Scoping When the management point is in both a neighbor and the site default boundary groups, the locality is 2. When the client fails to get content from the last server in the pool, it begins the process again. Select the “Default-First-Site-Name” site and press “OK”. When you enable this setting, Configuration Manager uses the boundary group functionality for the assigned management point. Instead, the client chooses at random from this list. For more information, see SMS_SCI_Component server WMI class. Depending on additional configurations, they can use roles in additional boundary groups. If the client still hasn't found content, it then expands its search for content sources to include the neighbor boundary groups. To manage fallback to the default site boundary group: Open the properties of the site default boundary group, and change the values on the Default Behavior tab. When you configure preferred management points, and a client organizes its list of management points, the client places the preferred management points at the top of its list. If you configure the content to distribute on-demand, and it isn't available on a distribution point when a client requests it, the site begins to transfer the content to that distribution point. This behavior includes continued use of a software update point that isn't associated with the client's current boundary group. Boundary groups assemble boundaries into logical groups for management. If you use a single, large boundary group for site assignment that doesn't reference any distribution points. For content like applications and software updates, which are downloaded by the client and not the task sequence engine, the client behaves as normal. By default, Configuration Manager excludes the default Teredo subnet (2001:0000:%). Clients on the main network received policy that included this protected management point, even though they couldn't communicate with it across a firewall. For more information, see Enable use of preferred management points. To address this problem now, use the Never fallback option to make sure that clients only fall back to management points with which they can communicate. I’ve been asked a couple of times if we should add all boundaries to the Default Site-Boundary-Group since the group is automatically configured for Site assignment. Append your subnets to the PropertyValue variable after 2001:0000:%,172.16.16.0. When you change the list, always read the existing value first. The following script is a sample way of changing this value. For more information on the client's behavior to acquire content during installation, see Client installation. If you enable distribution points in the site default boundary group to fallback, and a management point is colocated on a distribution point, the site also adds that management point to the site default boundary group. The management point provides clients a list of content locations that includes peer sources. These site systems are of the appropriate type associated with each boundary group that includes the client's current network location: During software distribution, clients request a location for deployment content on a valid content source. This process associates the new resource with an assigned site for use by the client push installation method. Boundaries and boundary groups in Microsoft Endpoint Configuration Manager play an important role in site assignment, policies , content download etc. After an additional 10 minutes (20 minutes total), if the client still hasn't found a distribution point with content, it expands its pool to include available servers from the second neighbor group, boundary group BG_C. This fallback time determines when the client begins to search for an available site system associated with the neighbor boundary group. This behavior is only during this process, and specifically for the purpose of these devices. Overlapping boundaries isn't a problem for content location. This setting reverses that priority for clients that are in the same subnet as the peer cache source. Use whichever boundary type or types you choose that work for your environment. To configure boundary groups, associate boundaries (network locations) and site system roles, like distribution points, to the boundary group. These clients can't use automatic site assignment. If you have a branch office with a faster internet link, you can prioritize cloud content. They can download content from an internet-based distribution point from their assigned site or a cloud-based distribution point. Changes to a boundary groups assigned site only apply to new site assignment actions. Make sure that each boundary in a boundary group isn't a member of another boundary group with a different site assignment. However, the client doesn't try to contact them or any other server until the initial 120-minute period elapses. Clients switch to the new software update point during their next software updates scan cycle. To use the new configuration, define explicit associations (links) from one boundary group to another. After 120 minutes, if the client hasn't established contact, it then begins fallback. You no longer configure individual distribution points to be fast or slow. This behavior allows the clients to use as content source locations the distribution points associated with that boundary group. Override this default behavior of 120 minutes by explicitly associating the default site boundary group to a current group. It's possible the client finds that server as a content source before falling back to use a neighbor boundary group.
