This chapter provides guidelines for using Grid Manager to manage Microsoft DHCP servers and for synchronizing DHCP data between Microsoft servers and the Grid. It discusses some features of the Microsoft DHCP servers only as they relate to the synchronization of data. Please review the Microsoft documentation for complete information about Microsoft DHCP servers and their features.
In addition, if you encounter technical issues with your Microsoft DHCP servers, contact Microsoft Technical Support or consult the Microsoft Support site at http://support.microsoft.com/. Some Windows versions require certain updates and hotfixes installed, so the Microsoft server can synchronize with the Grid member. For information about these requirements, see Requirements.

• About Microsoft DHCP Management

About Microsoft DHCP Management

Grid Manager enables you to centrally manage the DHCP data of multiple Microsoft DHCP servers from a single interface. Once the DHCP data is synchronized, you can use the Dashboard on Grid Manager to monitor DHCP and server operations, or organize DHCP data into Smart Folders. Through IPAM tools, such as network maps and IP maps, you can track and manage IP address usage in your networks and monitor DHCP range utilization. You can also run a network discovery to retrieve IP allocation for both managed and unmanaged devices— including virtualized resources. For information about the IPAM features, see Chapter 13, IP Address Management.

Synchronizing DHCP Data from Microsoft Servers

...

Note: Synchronizing IPv6 data is not supported.

...

As shown in Table 36.1, Microsoft servers and Infoblox DHCP servers represent DHCP data differently. Scopes on Microsoft servers are DHCP ranges on Infoblox DHCP servers. Additionally, Microsoft servers support split-scopes, which is a scope assigned to two Microsoft servers. Each scope has an exclusion range on opposite ends to specify the pool of IP addresses that the other Microsoft server allocates. On an Infoblox DHCP server, each scope in the split-scope is represented as a DHCP range with an exclusion range. Note that NIOS also synchronizes scopes assigned to more than two Microsoft servers, but they are not synchronized as split-scopes.
Fixed addresses on Infoblox DHCP servers are the same as reservations on Microsoft servers. Infoblox reservations, which are IP addresses that are excluded from DHCP, are not supported on Microsoft servers. Microsoft superscopes, which are used to group scopes, are represented as superscopes and can be managed from Infoblox DHCP servers.

You can also use the features in the IPAM tab, such as the Net Map and IP Map, to view and manage the Microsoft DHCP data. For information, see Chapter 13, IP Address Management.
