3.9 CIM Query Language (CQL) Filters
The CIM Query Language (CQL) is a query language for the Common Information Model (CIM) standard
from the Distributed Management Task Force (DMTF). It was designed to perform queries against the
CIM objects in a database.
3.9.1 CQL filter benefits
The two most distinct advantages of using CQL filters when performing enumerations are:
 The response time of enumerations will be accelerated as only the desired data is returned,
not the full data set.
 The workload on the network will be decreased as less bandwidth will be consumed per
enumeration as the amount of data being returned is less. This is more applicable to networks
that may have many systems that performing enumerations at or about the same time.
3.9.2 How to perform CQL enumerations using RECITE
Section 1.2 describes how to setup and run scripts using the RECITE PYTHON environment. Running
CQL filters requires running the CQL command directly from the RECITE command line. No scripts exist
because of the infinite number of use cases.
3.9.3 CQL filter example that enumerates all NIC attributes for a particular
port/partition
