C H A P T E R Fabric Overview The Cisco MDS 9000 Family NX-OS command-line interface (CLI) can configure and manage features such as VSANs, SAN device virtualization, dynamic VSANs, zones, distributed device alias services, Fibre Channel routing services and protocols, FLOGI, name server, FDMI, RSCN database, SCSI targets, FICON, and other advanced features.
Page 26: Dynamic Port Vsan Membership
VSAN membership to maintain fabric topology when a host or storage device connection is moved between two Cisco MDS switches or two ports within a switch. DPVM retains the configured VSAN regardless of where a device is connected or moved.
Page 27: Distributed Device Alias Services
Distributed Device Alias Services All switches in the Cisco MDS 9000 Family support Distributed Device Alias Services (device alias) on a per-VSAN basis and on a fabric-wide basis. Device alias distribution allows you to move host bus adapters (HBAs) between VSANs without manually reentering alias names.

Page 29: Configuring And Managing Vsans
You can achieve higher security and greater stability in Fibre Channel fabrics by using virtual SANs (VSANs) on Cisco MDS 9000 Family switches and Cisco Nexus 5000 Series switches. VSANs provide isolation among devices that are physically connected to the same fabric. With VSANs you can create multiple logical SANs over a common physical infrastructure.
Page 30: Vsans Topologies
Figure 2: Example of Two VSANs, on page 9 indicate that these features apply to any switch in the Cisco MDS 9000 Family. Figure 1: Logical VSAN Segmentation, on page 8 shows a fabric with three switches, one on each floor.

Default VSAN The factory settings for switches in the Cisco MDS 9000 Family have only the default VSAN 1 enabled. We recommend that you do not use VSAN 1 as your production environment VSAN. If no VSANs are configured, all devices in the fabric are considered part of the default VSAN.
Page 38: Displaying Isolated Vsan Membership
• Configured VSAN interface information is removed when the VSAN is deleted. Note The allowed VSAN list is not affected when a VSAN is deleted (refer to the Cisco MDS 9000 Family NX-OS Interfaces Configuration Guide ). Any commands for a nonconfigured VSAN are rejected. For example, if VSAN 10 is not configured in the system, then a command request to move a port to VSAN 10 is rejected.

While the port WWN (pWWN) of a device has to be specified to configure different features (zoning, QoS, and port security) in a Cisco MDS 9000 Family switch, you must assign the correct device name each time you configure these features. An incorrect device name may cause unexpected results. You can avoid this if you define a user-friendly name for a pWWN and use this name in all of the configuration commands, as required.

Page 208: Fspf Examples
Fault Tolerant Fabric with Redundant Links, on page 187 shows this arrangement. Because switches in the Cisco MDS 9000 Family support PortChanneling, each pair of physical links can appear to the FSPF protocol as one single logical link. By bundling pairs of physical links, FSPF efficiency is considerably improved by the reduced database size and the frequency of link updates.

FSPF Global Configuration FSPF Global Configuration By default, FSPF is enabled on switches in the Cisco MDS 9000 Family. Some FSPF features can be globally configured in each VSAN. By configuring a feature for the entire VSAN, you do not have to specify the VSAN number for every command. This global configuration feature also reduces the chance of typing errors or other minor configuration errors.

Other than in VSANs, runtime checks are not performed on configured and suspended static routes.

Cisco MDS 9000 Series Fabric Configuration Guide, Release 8.x...
Page 217: About Multicast Root Switch
FSPF provides the topology information to compute the distribution tree. Fibre Channel defines 256 multicast groups and one broadcast address for each VSAN. Switches in the Cisco MDS 9000 Family only use broadcast routing. By default, they use the principal switch as the root node to derive a loop-free distribution tree for multicast and broadcast routing in a VSAN.
Page 218: In-Order Delivery
Some Fibre Channel protocols or applications cannot handle out-of-order frame delivery. In these cases, switches in the Cisco MDS 9000 Family preserve frame ordering in the frame flow. The source ID (SID), destination ID (DID), and optionally the originator exchange ID (OX ID) identify the flow of the frame.
Page 219: About Reordering Portchannel Frames
PortChannel. Note Both switches on the PortChannel must be running Cisco SAN-OS Release 3.0(1) for this IOD enhancement. For earlier releases, IOD waits for the switch latency period before sending new frames. When the in-order delivery guarantee feature is enabled and a PortChannel link change occurs, the frames crossing the PortChannel are treated as follows: •...
Page 220: Enabling In-Order Delivery Globally
Only enable in-order delivery globally if this is a requirement across your entire fabric. Otherwise, enable IOD only for the VSANs that require this feature. Note Enable in-order delivery on the entire switch before performing a downgrade to Cisco MDS SAN-OS Release 1.3(3) or earlier. To enable in-order delivery for the switch, follow these steps:...

Page 255: Rscn Timer Configuration Distribution Using Cfs
Compatibility across various Cisco MDS NX-OS releases during an upgrade or downgrade is supported by conf-check provided by CFS. If you attempt to downgrade from Cisco MDS SAN-OS Release 3.0, you are prompted with a conf-check warning. You are required to disable RSCN timer distribution support before you downgrade.
Page 256: Verifying The Rscn Timer Configuration
This means different N-ports in a network can receive RSCNs at different times. Cisco Fabric Services (CFS) infrastructure alleviates this situation by automatically distributing the RSCN timer configuration information to all switches in a fabric. This also reduces the number of SW-RSCNs.
Page 257: Enabling Rscn Timer Configuration Distribution
Note You can determine the compatibility when downgrading to an earlier Cisco MDS NX-OS release using show incompatibility system command. You must disable RSCN timer distribution support before downgrading to an earlier release.

Displaying FICON Information, on page 290 • Default Settings, on page 298 About FICON The Cisco MDS 9000 Family supports the Fibre Channel Protocol (FCP), FICON, iSCSI, and FCIP capabilities within a single, high-availability platform (see Figure 54: Shared System Storage Network, on page 246).
Page 268: Ficon Requirements
The fabric binding feature helps prevent unauthorized switches from joining the fabric or disrupting current fabric operations (refer to the Cisco MDS 9000 Family NX-OS Security Configuration Guide ). The Registered Link Incident Report (RLIR) application provides a method for a switch port to send an LIR to a registered Nx port.

Configuring FICON MDS-Specific FICON Advantages MDS-Specific FICON Advantages This section explains the additional FICON advantages in Cisco MDS switches and includes the following topics: Fabric Optimization with VSANs Generally, separate physical fabrics have a high level of switch management and have a higher implementation cost.
Page 270: Fcip Support
FCIP Support Note While you can configure VSANs in any Cisco MDS switch, you only can enable FICON inupto eight of these VSANs. The number of VSANs configured depends on the platform. Mainframe users can think of VSANs as being like FICON LPARs in the MDS SAN fabric. You can partition switch resources into FICON LPARs (VSANs) that are isolated from each other, in much the same way that you can partition resources on a zSeries or DS8000.

FICON requires serialization of access among multiple mainframes, CLI, and SNMP sessions be maintained on Cisco MDS 9000 Family switches by controlling device allegiance for the currently executing session. Any other session is denied permission to perform configuration changes unless the required allegiance is available.
Page 290: Automatically Saving The Running Configuration
1 allegiance Automatically Saving the Running Configuration Cisco MDS NX-OS provides an option to automatically save any configuration changes to the startup configuration. This ensures that the new configuration is present after a switch reboot. By default, the Active=Saved active equals saved option is automatically enabled on any FICON VSAN.
Page 291: Configuring Ficon Ports
Configuring FICON Ports Note If active equals saved is enabled, the Cisco NX-OS software ensures that you do not have to perform the copy running startup command for the FICON configuration as well. If your switch or fabric consists of multiple FICON-enabled VSANs, and one of these VSANs have active equals saved enabled, changes made to the non-FICON configuration results in all configurations being saved to the startup configuration.

Page 304: Copying Ficon Configuration Files
The FICON port-swapping feature causes all configurations associated with old-port-number and new port-number to be swapped, including VSAN configurations. Cisco MDS switches allow port swapping for nonexistent ports as follows: • Only FICON-specific configurations (prohibit, block, and port address mapping) are swapped.
Page 305: About Port Swapping
PortChannel. • Before performing a port swap, the Cisco NX-OS software performs a compatibility check. If the two ports have incompatible configurations, the port swap is rejected with an appropriate reason code. For example, if a port with BB_credits as 25 is being swapped with an OSM port for which a maximum of 12 BB_credits is allowed (not a configurable parameter), the port swapping operation is rejected.
