Filtering the List of Nodes
Describes how to setup search expressions and filter nodes based on specific criteria.
About this task
The filter lets you build search expressions to provide sophisticated filtering capabilities for locating specific data on views that display a large number of nodes. Expressions are implicitly connected by the AND operator.

Filtering the List Using the CLI
About this task
Use the node list command with the
-filter option, to specify large numbers of nodes by
matching specified values in specified fields rather than by typing the name of
each node explicitly. For example, you can retrieve all nodes on a specific
subnet as follows:
maprcli node list -filter [ip==20.30.40.*]For more information, see Filters.
