NAME Get-NsxDynamicCriteria



SYNOPSIS

Retrieves Dynamic Member Criteria from the specified Dynamic Member Set.





SYNTAX

Get-NsxDynamicCriteria [-DynamicMemberSet] <Object> [-Index <String>] [-Connection <PSObject>] [<CommonParameters>]





DESCRIPTION

NSX Security Groups can have 3 types of membership configured, Dynamic

Criteria, Static Members and Exclude Members.



One or more Dynamic Criteria combine to make a Dynamic Member Set, and one

or more Dynamic Member Sets combine to define the Dynamic Membership of a

given security group.



In order to allow the configuration of a security groups Dynamic Membership

with an aritrary number of Dynamic Criteria Member Sets that contain an

arbitrary number of Dynamic Criteria in a flexible way, PowerNSX provides

the following abstractions.



Creation of individual Dynamic Criteria is accomplished with

New-NsxDynamicCriteriaSpec.



One or more Dynamic Criteria can be added to a Dynamic Member Set at creation

time with Add-NsxDynamicMemberSet and specifying the required Dynamic

Criteria Spec objects at creation time.



One or more Dynamic Criteria can be added to an existing Dynamic Member Set

after the fact with Add-NsxDynamicCriteria or removed with

Remove-NsxDynamicCriteria.



One or more Dynamic Member sets can be added to a security groups overall

Dynamic Membership definition using Add-NsxDynamicMemberSet or removed using

Remove-NsxDynamicMemberSet



A Security Groups Dynamic Member definition can include multiple Dynamic

Member Sets in an logical AND/OR arrangement, and for each of the Dynamic

Member Sets, a match operator of ALL or ANY can be specified that determines

how multiple Dynamic Criteria combine within the set to define a match.



Get-NsxDynamicCriteria retrieves Dynamic Member Criteria from the specified

Dynamic Member Set as retrieved by Get-NsxDynamicMemberSet. While

Get-NsxDynamicMemberSet displays a text representation of the Dynamic

Criteria that belong to it, this cmdlet outputs individual objects

representing each criteria such that they can be filtered, and passed to

Remove-NsxDynamicCriteria.

2 2 webapp SecurityTag equals webapp

1 3 webapp ENTITY belongs_to vm-3961



Retrieves all Dynamic Criteria from ALL Dynamic Member Sets of the security group webapp. This is probably not

what you want to do.

Output is formatted as a table.

----- -------------- ----------------- --- --------- -----

1 1 webapp VMName contains webapp

2 1 webapp SecurityTag contains webapp

3 1 webapp ComputerName contains webapp



Retrieves all Dynamic Criteria from the first Dynamic Member Set of the security group webapp. This probably IS

what you want to do! :)

Output is formatted as a table.
