Table 3-17 Add Block Type Parameters
Field
Description
Block Type Name
The name of the block type.
Parent Block Type
A block type can be a child of other block types including Any. A block type
with parent block type “None” is not a child to any other block type. When a
block type has a parent, during auto allocation the Cisco Prime Network
Registrar IPAM allocation algorithm will include blocks of its own type, and of
its parent type in the result list.
Blocks of this type can be
attached to multiple
containers
If this box is checked, this block type can be associated with more than one
container. This feature allows blocks that are assigned this specific block type
to belong to multiple containers. This feature is useful for modeling blocks
assigned to multiple physical network devices (i.e., routers), such as loopback
or point-to-point space.
Include in Regression
Analysis
If this box is checked, blocks assigned this block type are included in the
regression analysis. For many block types (such as point to point, or
loopback), it does not make sense to calculate regression analysis for trending
purposes. Because the regression analysis is CPU intensive, in a large
deployment it is important to calculate the regression analysis only against
blocks that need the trending.
Maintain History Records
If checked, Container History and Block History records will be kept for this
block type. The history records are created each time the Global Utilization
Rollup task is run.
Valid Block Sizes
A block type can be constrained to discrete sizes of an address block for block
allocation. Select the “Root Block Sizes” link to constrain block sizes for root
block allocation for the block type. Select the “Child Block Sizes” link to
constrain block sizes for child block allocation for the block type.
3.14.1 Constraining Block Sizes
To constrain block allocation for the block type to discrete sizes of an address block, select
To constrain block allocation for the block type to discrete sizes of an address block, select
either the
Root Block Sizes link for root block allocation or Child Block Size link for child
block allocation. Selecting either link opens the Edit Block Sizes screen.
Select all block sizes allowable for allocation for the block type. All unchecked block sizes will
Select all block sizes allowable for allocation for the block type. All unchecked block sizes will
not be allowed for allocation. Use the
IPv4 tab to edit settings for IPv4 block size addressing.
Use the
IPv6 tab to edit settings for IPv6 block size addressing.
Whether or not a block type is allowed block allocation for a specific size will be determined
by examining the block size constraint rules defined at the block type definition and rules
defined at the administrator for all roles owned by the user seeking to allocate blocks. See the
block type policies
Block Type Size Allocation Rules for further details on this. Note that if
a block type is constrained by a block size at the block type definition, it may not be
unconstrained at the administrator role block type policy. Block types may only be further
constrained by block size at the administrator role policy level, not the other way around.

type was successfully added, the Block Type List screen displays
