To use one of the enumeration modes like EnumerateEPR or EnumerateEPRandObject, call the Enumerate operation with EnumerationMode enabled. You can also specify the enumeration mode in the constructor.

$result = $client->Enumerate(class_name => 'CIM_Processor',
                                 #namespace => 'root/cimv2', #if needed.
                                 enummode => 'EnumerateEPR'
                                 );

To perform operations on vendor-specific classes, you must register them first with the client. The actual URL depends on your WS-Management software.

$client->register_class_ns(Linux => 'http://www.dmtf.org/linux');

# It is better to use the Generic Operations module, built on top of this module.
