Determining the Software Version
Note
To determine the version of the Cisco MDS 9000 FabricWare software currently running on a Cisco MDS 9020 Fabric Switch using the CLI, log into the switch and enter the show version EXEC command.
To determine the version of the Cisco MDS 9000 FabricWare software currently running on a Cisco MDS 9020 Fabric Switch using the Fabric Manager, from the Switches tab in the information pane, locate the switch using its IP address, logical name, or WWN, and then check its version in the Release column.
Image Upgrade
The Cisco MDS 9000 FabricWare software is designed for high availability environments. As new software releases become available, you can nondisruptively upgrade the switch.
Limitations and Restrictions
This section lists the limitations and restrictions for this release.
Merging Fabrics
You must only configure pWWN-type zoning on an MDS switch running Cisco SAN-OS if there is a Cisco MDS 9020 switch running FabricWare in the same fabric to avoid Inter-Switch Link (ISL) isolation. It is important to remove all non-pWWN-type zone entries prior to merging fabrics.
For additional information on zoning, refer to the Cisco MDS 9020 Fabric Switch Configuration Guide and Command Reference.
Caveats
This section lists the open and resolved caveats for this release. Use Table 3 to determine the status of a particular caveat. In the table, "R" indicates a resolved caveat, "O" indicates an open caveat, and "C" indicates a closed caveat.

Closed FabricWare Caveats
•
Symptom: When Cisco VPN client version 3.6.3 is installed but not used, some of the ISLs might be missing from the Fabric Manager map if an MDS 9020 switch is used as a seed switch for the discovery of the fabric. An SNMP GET-BULK timeout occurs because of an incompatibility between the TCP/IP stack on the MDS 9020 switch and the client stack being configured or tuned during installation of the Cisco VPN client on the client itself.
Workaround: If you connect through Cisco VPN client 3.6.3 and then open Fabric Manager, it will discover properly.
Open FabricWare Caveats
•
Symptom: If a Cisco MDS 9020 switch is used as the seed switch for Fabric Manager discovery in a mixed fabric of Cisco MDS 9000 Series switches, some ISL links might be missing.
Workaround: Use a Cisco MDS 9100, Cisco MDS 9200, or Cisco MDS 9500 series switch as the seed switch or rediscover the network if it is not possible to have them as seed switches.
•
Symptom: When a fabric including a Cisco MDS 9020 Fabric Switch and third party devices is discovered using Fabric Manager, where the Cisco MDS 9020 Fabric Switch is used as a seed for the discovery, the map might not display some of the end devices (hosts and disks) connected to the third party switches. When the zone with these devices is highlighted on the Fabric Manager map display, the devices on the third party switches are shown as 'not in fabric'. CLI displays for FCNS and zone information are correct.
Workaround: None.
Related Cisco SAN-OS Caveats
Cisco MDS 9000 Family switches must be running Cisco MDS SAN-OS Release 2.1(2) to work properly with a Cisco MDS 9020 switch. This section lists the Cisco SAN-OS caveats related to Cisco FabricWare.
The following caveats are resolved in Cisco SAN-OS Release 2.1(2):
•
Symptom: If the Cisco MDS 9020 switch is loaded with more devices than recommended, timeouts may occur on a Cisco MDS 9000 Family switch running Cisco MDS SAN-OS Release 2.1(1a) or earlier, when Name Server queries are issued to the loaded Cisco MDS 9020 switch. The queries are retried to the point where the Cisco MDS 9000 Family switch can crash. In Cisco MDS FabricWare Release 2.1(2), the retries are limited to mitigate this effect.
Workaround: Upgrade the Cisco MDS 9000 Family switches to Cisco MDS SAN-OS Release 2.1(2).
•
Symptom: If a device registers symbolic port names on the Cisco MDS 9020 switch, the same symbolic port names cannot be properly propagated across VSANs through an IVR fabric where the Cisco MDS 9020 switch is an edge switch in the IVR topology.
Workaround: None.
•
Symptom: When devices with specific FC4-type log-in to a Cisco MDS 9000 Series switch and the Cisco MDS 9020 switch issues a GE_FT query to a Cisco MDS 9000 Series switch running Cisco MDS SAN-OS Release 2.1(1a) or earlier, the query might be rejected. This will result in that name server entry on the Cisco MDS 9020 switch not having FC4 type information of the device logged into the Cisco MDS 9000 Series switch. The affected FC4 type is 255.
Workaround: Upgrade the Cisco MDS 9000 Family switches to Cisco MDS SAN-OS Release 2.1(2).

Reporting Security Problems in Cisco Products
Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you might have identified a vulnerability in a Cisco product, contact PSIRT:
•
An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.
•
In an emergency, you can also reach PSIRT by telephone:

Obtaining Technical Assistance
Cisco Technical Support provides 24-hour-a-day award-winning technical assistance. The Cisco Technical Support & Documentation website on Cisco.com features extensive online support resources. In addition, if you have a valid Cisco service contract, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not have a valid Cisco service contract, contact your reseller.
Cisco Technical Support & Documentation Website
The Cisco Technical Support & Documentation website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, at this URL:
http://www.cisco.com/techsupport
Access to all tools on the Cisco Technical Support & Documentation website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:

Note
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete list of Cisco TAC contacts, go to this URL:
http://www.cisco.com/techsupport/contacts
Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
