CHAPTER 12
Advanced Features and Concepts
This chapter describes the advanced features provided in switches in the Cisco MDS 9000 Family. It includes
the following sections:
• Common Information Model, on page 299
• Fibre Channel Time-Out Values, on page 299
• Organizationally Unique Identifiers, on page 304
• World Wide Names, on page 305
• FC ID Allocation for HBAs, on page 307
• Switch Interoperability, on page 309
• Default Settings, on page 316
Common Information Model
Common Information Model (CIM) is an object-oriented information model that extends the existing standards
for describing management information in a network/enterprise environment.
CIM messages are independent of platform and implementation because they are encoded in N Extensible
Markup Language (XML). CIM consists of a specification and a schema. The specification defines the syntax
and rules for describing management data and integrating with other management models. The schema provides
the actual model descriptions for systems, applications, networks, and devices.
For more information about CIM, refer to the specification available through the Distributed Management
Task Force (DMTF) website at the following URL: http://www.dmtf.org/
The CIM Functionality and SMI-S is now supported with Cisco Prime Data Center Network Manager (DCNM).
Please refer to “Cisco Prime DCNM Installation Guide” and “SMI-S and Web Services Programming Guide,
Cisco DCNM for SAN.
Note
Fibre Channel Time-Out Values
You can modify Fibre Channel protocol related timer values for the switch by configuring the following
time-out values (TOVs):
