Configuring Fabric Configuration Servers
This chapter describes the Fabric Configuration Server (FCS) feature provided in the Cisco MDS 9000
Family of directors and switches. It includes the following sections:
• About FCS, page 63-1
• Displaying FCS Discovery, page 63-3
• Displaying FCS Elements, page 63-3
• Creating an FCS Platform, page 63-4
• Displaying FCS Fabric Ports, page 63-5
• Default Settings, page 63-6
About FCS
The Fabric Configuration Server (FCS) provides discovery of topology attributes and maintains a
repository of configuration information of fabric elements. A management application is usually
connected to the FCS on the switch through an N port. The FCS views the entire fabric based on the
following objects:
• Interconnect element (IE) object—Each switch in the fabric corresponds to an IE object. One or
more IE objects form a fabric.
• Port object—Each physical port in an IE corresponds to a port object. This includes the switch ports
(xE, Fx, and TL ports) and their attached Nx ports.
• Platform object—A set of nodes may be defined as a platform object to make it a single manageable
entity. These nodes are end-devices (host systems, storage subsystems) attached to the fabric.
Platform objects reside at the edge switches of the fabric.
Each object has its own set of attributes and values. A null value may also be defined for some attributes.
In the Cisco MDS 9000 Family switch environment, multiple VSANs constitute a fabric, where one
instance of the FCS is present per VSAN.
As of Cisco NX-OS Release 4.1(1), FCS supports the discovery of virtual devices. The fcs
virtual-device-add command, issued in FCS configuration submode, allows you to discover virtual
devices in a particular VSAN or in all VSANs. The devices that are zoned for IVR must be discovered
with this command and have request domain_ID (RDI) enabled, before activating the IVR zone set.
