Configuring Fabric Configuration Server
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:
Information 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.
If you have attached a management application to a switch, all the frames directed towards the FCS in the switch are part of the port VSAN in the switch port (Fx port). Your view of the management application is limited only to this VSAN. However, information about other VSANs that this switch is part of can be obtained either through the SNMP or CLI.
In Figure 13-1 Management Application 1 (M1) is connected through an F port with port VSAN ID 1, and Management Application 2 (M2) is connected through an F port with port VSAN ID 2. M1 can query the FCS information of switches S1 and S3, and M2 can query switches S3 and S4. Switch S2 information is not known to both of them. FCS operations can be done only on those switches that are visible in the VSAN. Note that M2 can send FCS requests only for VSAN 2 even though S3 is also a part of VSAN 1.

Significance of FCS
This section lists the significance of FCSs.
- FCSs support network management including the following:
– N port management application can query and obtain information about fabric elements.
– SNMP manager can use the FCS management information base (MIB) to start discovery and obtain information about the fabric topology.
- FCSs support TE and TL ports in addition to the standard F and E ports.
- FCS can maintain a group of modes with a logical name and management address when a platform registers with it. FCSs maintain a backup of all registrations in secondary storage and update it with every change. When a restart or switchover happens, FCSs retrieve the secondary storage information and rebuild its database.
- SNMP manager can query FCSs for all IEs, ports, and platforms in the fabric.

Configuring FCS
The Fabric Configuration Server (FCS) provides discovery of topology attributes and maintains a repository of configuration information of fabric elements.
This section includes the following topic:
Specifying a FCS Name
You can specify if the unique name verification is for the entire fabric (globally) or only for locally (default) registered platforms.
Restrictions
- Set this command globally only if all switches in the fabric belong to the Cisco MDS 9000 Family.
Detailed Steps
To enable global checking of the platform name, follow these steps:
|
|
|
Step 1 |
switch# config t switch(config)# |
Enters configuration mode. |
Step 2 |
switch(config)# fcs plat-check-global vsan 1 |
Enables global checking of the platform name. |
switch(config)# no fcs plat-check-global vsan 1 |
Disables (default) global checking of the platform name. |
To register platform attributes, follow these steps:
|
|
|
Step 1 |
switch# config t switch(config)# |
Enters configuration mode. |
Step 2 |
switch(config)# fcs register switch(config-fcs-register)# |
Enters the FCS registration submode. |
Step 3 |
switch(config-fcs-register)# platform name SamplePlatform vsan 1 switch(config-fcs-register-attrib)# |
Enters the FCS registration attributes submode. |
switch(config-fcs-register)# no platform name SamplePlatform vsan 1 switch(config-fcs-register)# |
Deletes a registered platform. |
Step 4 |
switch(config-fcs-register-attrib)# mgmt-addr 1.1.1.1 |
Configures the platform management IPv4 address. |
switch(config-fcs-register-attrib)# no mgmt-addr 1.1.1.1 |
Deletes the platform management IPv4 address. |
switch(config-fcs-register-attrib)# mgmt-addr 2001:0DB8:800:200C::417A |
Configures the platform management IPv6 address. |
switch(config-fcs-register-attrib)# no mgmt-addr 2001:0DB8:800:200C::417A |
Deletes the platform management IPv6 address. |
Step 5 |
switch(config-fcs-register-attrib)# nwwn 11:22:33:44:55:66:77:88 |
Configures the platform node name. |
switch(config-fcs-register-attrib)# no nwwn 11:22:33:44:55:66:77:88 |
Deletes the platform node name. |
Step 6 |
switch(config-fcs-register-attrib)# type 5 |
Configures the fc-gs-3 defined platform type. |
switch(config-fcs-register-attrib)# no type 5 |
Deletes the configured type and reverts the switch to its factory default of unknown type. |
Step 7 |
switch(config-fcs-register-attrib)# exit |
Exits the FCS registration attributes submode. |
Step 8 |
switch(config-fcs-register)# exit switch(config)# |
Exits the FCS registration submode. |

|
|
