Configuring Fabric Configuration Servers

This chapter describes the Fabric Configuration Server (FCS) feature provided in switches in the Cisco MDS 9000 Family. It includes the following sections:

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 its 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 their 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.

If you have attached a management application to a switch, all the frames directed towards the FCS in the switch is a part of the port VSAN in the switch port (Fx port). Hence 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 SNMP or CLI.

In Figure 2 Management Application 1 (M1) is connected through an F port with a port VSAN ID 1 and Management Application 2 (M2) is connected through an F port with a port VSAN ID 2. M1 can query FCS info 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

•Network Management

–N port management application can query and obtain information about the fabric elements.

–SNMP Manager—A SNMP Manager can use the FCS management information base (MIB) to start discovery and obtain information about the fabric topology.

•The FCS supports TE and TL ports in addition to the standard F and E ports.

•The FCS can maintain a group of modes with a logical name and management address when a platform registers with it. FCS maintains a backup of all registrations in secondary storage and updates it with every change. When a restart or switchover happens, FCS will retrieve the secondary storage information, and rebuild its database.

•The SNMP manager can query FCS for all the IEs, ports, and platforms in the fabric.

Configuring FCS

Use the fcs plat-check-global command to specify if the platform name or node name uniqueness verification is for the entire fabric (globally) or only for locally (default) registered platforms.

Note Set this command globally only if all switches in the fabric belong to the Cisco MDS 9000 Family.

To enable global checking of the platform name, follow these steps:
Command

Purpose
Step 1
switch# config t
switch(config)#
Enters configuration mode.
Step 2
switch(config)# fcs plat-check-global vsan 1 
switch(config)# 
Enables global checking of platform name.
switch(config)# no fcs plat-check-global vsan 1 
switch(config)# 
Disables (default) global checking of platform name.
To register platform attributes, follow these steps:
Command

Purpose
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 
switch(config-fcs-register-attrib)# 
Configures the platform management address.
switch(config-fcs-register)# no mgmt-addr 
1.1.1.1
switch(config-fcs-register)# 
Deletes all management addresses on the platform.
Step 5
switch(config-fcs-register-attrib)# nwwn 
11:22:33:44:55:66:77:88
switch(config-fcs-register-attrib)# 
Configures the platform node name.
switch(config-fcs-register)# no nwwn 
11:22:33:44:55:66:77:88
switch(config-fcs-register)# 
Deletes the platform node name.
Step 6
switch(config-fcs-register-attrib)# type 5
switch(config-fcs-register-attrib)# 
Configures the fc-gs-3 defined platform type.
switch(config-fcs-register)# no type 5
switch(config-fcs-register)# 
Deletes the configured type and reverts the switch to its factory default of unknown type.
Step 7
switch(config-fcs-register-attrib)# exit
switch(config-fcs-register)# 
Exits the FCS registration attributes submode
Step 8
switch(config-fcs-register)# exit
switch(config)# 
Exits the FCS registration submode.
Displaying FCS Information

Use the show fcs commands to display the status of the WWN configuration (see Example 24-1 to 24-9).
