A unique value used by this host system to identify this conceptual row in the 'xcmSimpleJobInterceptTable'. Usage: The future value of 'xcmJobClientId' from the XCMI Job Monitoring MIB which uniquely identifies this client's job. Usage: XCMI conforming management agents MAY choose to REJECT any attempt at row creation in the 'xcmSimpleJobInterceptTable' which specifies a value for 'xcmSimpleJobInterceptClientId' that does NOT conform to the 'XcmGlobalUniqueID' format (therefore cannot be appended onto the trap OID for any job-related traps). Usage: XCMI conforming management agents MAY choose to ACCEPT any attempt at row creation in the 'xcmSimpleJobInterceptTable' which specifies a value for 'xcmSimpleJobInterceptClientId' that is nonetheless unique in the scope of the managed system (but not append it onto the trap OID for any job-related traps). Usage: XCMI conforming management stations (ie, clients) shall ALWAYS submit an 'xcmJobClientId' in 'XcmGlobalUniqueID' format. XCMI conforming management agents (ie, servers and devices) shall ALWAYS append such an 'xcmJobClientId' onto the trap OID for any job-related traps. Usage: Non-XCMI conforming management stations (ie, clients) MAY submit a non-unique 'xcmJobClientId', although they may be otherwise strictly conformant DPA (ISO 10175) clients.
