Clients that previously assigned to a site don't reevaluate their site assignment based on changes to the configuration of a boundary group (or to their own network location). A relationship between these boundary groups can be established to allow clients to get content from another boundary group if their distribution point is offline for a given amount of time. If you use preferred management points, enable this option for the hierarchy, not from within the boundary group configuration. Starting in version 2002, depending on the configuration of your network, you can exclude certain subnets for matching. Then create a Boundary Group to include all the VPN boundaries. This behavior allows the clients to use as content source locations the distribution points associated with that boundary group. Import IP Boundaries and Boundary Groups PowerShell SCCM ConfigMgr This script is designed to work in harmony with the Export Sites and Subnets to CSV script I blogged about recently. This search of additional groups is called fallback. This happens for one of two reasons: You add the same boundary to multiple boundary groups. For more information, see Configure fallback behavior. If a device is in more than one boundary group, the following behaviors apply for these settings: This setting is enabled by default. For more information, see Site assignment. It uses the failover times for prioritizing the neighbor boundary groups. Before designing your strategy choose wisely on which bounday type to use. When a client fails to find content from a distribution point in the current group, this time is when the client begins to search content locations from neighbor boundary groups. Boundaries and Boundary Groups in SCCM As per Microsoft, a boundary is a network location on the intranet that can contain one or more devices that you want to manage. For more information, see Preferred management points. To use this option, enable Clients prefer to use management points specified in boundary groups in Hierarchy Settings. You set the distribution point fallback time to 20. The refresh cycle is 24 hours, or when the Configuration Manager agent service restarts. For each type of supported site system role, configure independent settings for fallback to the neighbor boundary group. On the Home tab, in the Create group, select Create Boundary Group. The task sequence tries to acquire content in the following order: Distribution points in the current boundary group, Distribution points in a neighbor boundary group. Boundaries and boundary groups in Microsoft Endpoint Configuration Manager play an important role in site assignment, policies , content download etc. Also add to the default site boundary group another distribution point that's on the site server. Allow clients to use distribution points from the default site boundary group: For this deployment, the task sequence can fall back to distribution points in the default site boundary group. For example if you are setting up a new ConfigMgr environment and there's always and old one yo. If you’re unsure of which type of boundary to use you can read Jason Sandys excellent postabout why you shouldn’t use IP Subnet boundaries. To use the new configuration, define explicit associations (links) from one boundary group to another. clients use boundary group’s for site assignment, content location (DP), SUP, MP, and SMP. Common scenarios for enabling this option: Your boundary group design for content distribution includes one large boundary group that overlaps other smaller boundary groups. In the Configuration Manager console, go to the Administration workspace, expand Hierarchy Configuration, and select the Boundary Groups node. Jason Sandys had mentioned about boundaries in almost all of his sessions. SMP doesn't use fallback relationships. Then select a site from the Fallback site drop-down list. To modify the site assignment and associated site system server configuration, switch to the References tab in the boundary group Properties window. I can control when devices start to fall back. When fallback starts, the client receives a list of all software update points in its current boundary group. This group is named Default-Site-Boundary-Group. 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. 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. 3: The specified management point is in the local or current boundary group. When overlapping occurs, Configuration Manager creates a list of all site systems referenced by all boundary groups that include a client's location. Then it expands its search to additional servers. roles. Boundaries in Configuration Manager define network locations on your intranet. You configure the same setting for boundary group B to 130 minutes. It searches each distribution point for two minutes, and then switches to the next distribution point in the boundary group. For more information, see Boundary groups. 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. The examples in this article use the site name XYZ. For more information, see the following procedures: Starting in version 2002, to help you better identify and troubleshoot device behaviors with boundary groups, you can view the boundary groups for specific devices. After 10 more minutes, the client expands the search to include software update points from boundary group B. The Configuration Manager client installer, ccmsetup, can get installation content from a local source or via a management point. For more information about boundary groups in build 2002 and later, please read here. The client continues to contact each distribution point for two minutes, and then switches to the next server in its pool. It doesn't apply when the task sequence downloads content. Export boundaries from SCCM with powershell Script that will export boundaries from Configuration Manager with the help of powershell and out put it in to a .CSV file. 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. There was no option to fall back to distribution points in other boundary groups that might have the necessary content. 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. For more information, see. A client tries to use a preferred management point from its assigned site before using one not configured as preferred from its assigned site. A boundary group can have more than one relationship, each with a specific neighbor boundary group. When you change the list, always read the existing value first. The client continues to use an existing software update point, even when it isn't in the client's current boundary group. It also reflects the Boundary group to Site Server relationship. Configuration Manager doesn't apply any precedence or deterministic ordering to this list based on overlapping boundaries and boundary groups. This location is a boundary in a boundary group with a different site assignment. Otherwise the client won't use delivery optimization. Any boundary group a client can use because of an association between that client's current boundary group and another group is called a neighbor boundary group. This list includes all management points from the client's assigned site. This behavior is intentional. Select the boundary group you want to modify, and select Properties in the ribbon. In the Create Boundary Group dialog box, on the General tab, specify a Name for this boundary group. You have a single large boundary group for all remote office locations. This fallback time determines when the client begins to search for an available site system associated with the neighbor boundary group. Software update point This pool now includes servers from both the BG_A and BG_B boundary groups. For example, a client roams to a new network location. 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. T his all started with a simple boundary review when I figured It might be handy to have a boundary report. This behavior is a change from previous versions where clients tried to connect to a distribution point for up to two hours. This information is site data and only available on primary sites. This pool includes the servers in boundary group A, which were previously added to the pool of available servers. A client's current boundary group is a network location that's defined as a boundary assigned to a specific boundary group. The purpose of the Default Site-Boundary-Group is to service clients that are not served by any other boundary group (that being local boundary group or neighbor boundary group). For more information, see Manually switch clients to a new software update point. If you define relationships on the boundary group, the management point returns distribution points in the following order: The client setup process doesn't use the fallback time. Append additional subnets to the list, and then set the new value. If the management point in the current boundary group later comes back online, the client returns to the local management point on the next refresh cycle. To remove a server from this boundary group, select the server and then select Remove. On the Relationships tab of the boundary group properties, there's a column for management point. This article includes procedures on how to configure boundary groups. To locate content as quickly as possible, it immediately falls back to the next boundary group. Clients use local management points first (locality 3), remote second (locality 2), then fallback (locality 1). This behavior applies to the Configuration Manager client. Clients randomly select the first distribution point from the pool of available servers in the client's current boundary group (or groups). By default, Configuration Manager excludes the default Teredo subnet (2001:0000:%). This behavior makes sure that a client always receives a list of management points. 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 are logical groups of boundaries that you configure. To modify the configuration of an existing relationship, select the boundary group in the list, and select Change. Jason Adams also had couple of discussions about boundaries in MMS 2013.Find our more about “Overlapping Site Boundaries in ConfigMgr 2007 or 2012” . Then , in my boundary group Relationship tab I create a fallback relationship from the London office to my Manchester and Seattle offices. For more information, see management points. On the Relationships tab, add boundary groups to use as a neighbor boundary group. After 10 minutes, Configuration Manager adds the software update points from boundary group A to the pool of available servers. Both are well connected to the first group's boundary locations. 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. You can configure each boundary group with an assigned site for clients. 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. This configuration allows clients to use the CMG for client communication according to boundary group relationships. When a client fails to find an available site system in its current boundary group, the configuration of each relationship determines when it begins to search a neighbor boundary group. If a device is in more than one boundary group, make sure to enable this setting on all boundary groups for the device. With this configuration, you can configure fallback for each type of site system to different neighbors to occur after different periods of time. The management point provides clients a list of content locations that includes peer sources. This behavior includes continued use of a software update point that isn't associated with the client's current boundary group. This process associates the new resource with an assigned site for use by the client push installation method. Boundary group fallback times start when the client first fails to reach its original server. Clients on the main network received policy that included this protected management point, even though they couldn't communicate with it across a firewall. Depending on additional configurations, they can use roles in additional boundary groups. Overlapping occurs when a client's location maps to multiple boundary groups. When a client fails to find a content source from its current boundary group, the time you configure determines when it begins to search for content sources from its neighbor boundary group. Boundary groups and Software Update Points. One of those is while upgrading the OS on all the Site Servers pre SCCM upgrade. You no longer configure individual distribution points to be fast or slow. Each primary site has a new default boundary group named Default-Site-Boundary-Group. The client falls back to neighbors of any of those original boundary groups. 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. From this build version, we can now identify the client boundary group for site assignment and content troubleshooting within the configuration … Select the check box for one or more servers, and select OK. When you enable this setting, Configuration Manager uses the boundary group functionality for the assigned management point. You add separate boundaries that include the client's location to different boundary groups. - [Instructor] Before we can do a lot of configuration, we've got to create a boundary group and a boundary group represents network locations on the internet, or the local area network where configuration manager clients are located. This configuration is beneficial for VPN or branch office clients where it might be better to manage them via a CMG than over the VPN or WAN connection. For more information, see Enable use of preferred management points. Posted on September 16, 2017 by Eswar Koneti | 5 Comments | 5,155 Views. On the General tab, select the checkbox to Use a fallback site. For more information on the client's behavior to acquire content during installation, see Client installation. Instead, each site system associated with a boundary group is treated the same. SCCM 2010 Released Microsoft released the latest version of Microsoft Endpoint Configuration Manager 2010 #SCCM 2010 Released Microsoft released the latest version of Microsoft Endpoint Configuration Manager 2010. When designing your boundary strategy, we recommend you use boundaries that are based on Active Directory sites before using other boundary types. When an internet machine connects to the VPN, it will continue scanning against the CMG software update point over the internet. The client's pool of valid content source locations includes DP_A1, DP_A2, DP_B1, and DP_B2. Many of these changes and concepts work together. 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. For more information, see Understand how clients find site resources and services. To configure boundary groups, associate boundaries (network locations) and site system roles, like distribution points, to the boundary group. Right-click on Boundary Groups and choose Create Boundary Group. You no longer explicitly configure a distribution point to be used for fallback. This group contains distribution points DP_C1 and DP_C2. The client uses fallback to the default site boundary group as a safety net for content that isn't available from any other location. This example can be applied to other site system roles that use boundary groups. We utilise local DPs at remote sites so that computers can be imaged across the LAN, not the … When the client expands its search, the site provides any boundary groups configured for less than 120 minutes. 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. In the Fallback Boundary Groups window, select the boundary group to configure. By default, Configuration Manager includes the Teredo subnet in this list. 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. When the software update point changes, the client synchronizes data with the new server, which causes significant network usage. This location may be a distribution point, or a peer cache source. On the General tab, select Clients prefer to use management points specified in boundary groups. In the Fallback Boundary Groups window, you select the Main Office boundary group. 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. When you configure an explicit link to this default site boundary group from another boundary group, you override these default settings. After two minutes, if the client hasn't found the content, it switches to a new distribution point and tries to get content from that server. The boundary groups you link to are called neighbor boundary groups. Boundary groups that are logical groups of boundaries that provide clients access to resources such as updates, operating systems, installations et cetera. Changes to a boundary groups assigned site only apply to new site assignment actions. For more information about client site assignment, see Using automatic site assignment for computers. To configure fallback behavior, switch to the Relationships tab in the boundary group Properties window. A boundary group can have more than one relationship. Where boundaries based on Active Directory sites are not an option, then use IP subnet or IPv6 b… 2: The specified management point is in a remote or neighbor boundary group. This behavior enables the client to rapidly search through the expanding list of potential software update points. For example, when you configure a relationship to a specific boundary group, set fallback for distribution points to occur after 20 minutes. Additionally, the result of setting Allow clients to use a fallback source location for content on a deployment type for applications has changed. SCCM Configmgr Report for Boundary group relationships with Fallback Sites Beginning with Configmgr Version 1702, clients use boundary groups to find a new software update point. The client's pool of valid content source locations includes DP_A1 and DP_A2. Then configure boundary groups at individual primary sites. Go to the Administration expand Hierarchy Configuration, and select the Boundary Groups node. During OS deployment, clients request a location to send or receive their state migration information. It then searches the expanded group of source locations that includes the distribution points from both boundary groups. When the management point is in the current boundary group and either a neighbor or the site default boundary group, the locality is 3. This setting also affects applying Group IDs for Delivery Optimization. For each boundary group in your hierarchy, you can assign: One or more boundaries. Example of boundary groups and fallback times: The client begins searching for content from distribution points in its current boundary group (BG_A). Use boundary groups in Configuration Manager to logically organize related network locations (boundaries) to make it easier to manage your infrastructure. The following script is a sample way of changing this value. If a client is roaming and not a member of a boundary group, the value is blank. For controlled selection and fallback behavior, add individual software update points to different boundary groups. Right-click on the blank space and choose “Create Boundary Group”. If the client still hasn't found content, it then expands its search for content sources to include the neighbor boundary groups. When the task sequence runs, it prefers peer cache sources over distribution points. When you switch to a new server, the devices use fallback to find that new server. The following are the key changes to boundary groups and how clients find content in Configuration Manager current branch. If you add both the state migration point and distribution point roles to the same site system server, don't configure fallback on its boundary group.
