Deprecated Features Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • Cisco MDS 9000 8-port 10-Gbps Fibre Channel over Ethernet (FCoE) module • Cisco MDS 9000 48-port 8-Gbps Advanced Fibre Channel Switching module • Cisco MDS 9000 32-port 8-Gbps Advanced Fibre Channel Switching module You cannot bring up these modules if these features are already configured.
Licensed Cisco NX-OS Software Packages Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m Mainframe Package The Cisco MDS 9000 Mainframe package uses the FICON protocol and allows control unit port management for in-band management from IBM S/390 and z/900 processors. FICON VSAN support is provided to help ensure true hardware-based separation of FICON and open systems. Switch cascading, fabric binding, and intermixing are also included in this package.
Limitations and Restrictions Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m I/O Accelerator Package The Cisco I/O Accelerator (IOA) package activates IOA on the Cisco MDS 9222i fabric switch, the Cisco MDS 9000 18/4 Multiservice Module (MSM-18/4), and on the SSN-16 module. The IOA package is licensed per service engine and is tied to the chassis.
Limitations and Restrictions Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • PPRC Not Supported with FCIP Write Acceleration, page 34 • Configuring a Persistent FCID in an IVR Configuration with Brocade Switches, page 34 • In Cisco MDS NX-OS Release 5.2(x), you cannot install a FCoE module in a switch that is running DMM, SME, or IOA. • Link traps for FCoE devices are sent only when a VFC interface flaps.
Limitations and Restrictions Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m InterVSAN Routing When using InterVSAN Routing (IVR), it is recommended to enable Cisco Fabric Services (CFS) on all IVR-enabled switches. Failure to do so may cause mismatched active zone sets if an error occurs during zone set activation. Java Web Start When using Java Web Start, it is recommended that you do not use an HTML cache or proxy server.

Limitations and Restrictions Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • Rate Mode: dedicated • Buffer Credits: default value When you configure port mode to auto or E for all ports in the global buffer pool, you need to reconfigure buffer credits on one or more of the ports. The total number of buffer credits configured for all the ports in the global buffer pool should be reduced by 64.

Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m Table 16 Open Caveats and Resolved Caveats Reference (continued) DDTS Number NX-OS Software Release (Open or Resolved) NX-OS Software Release (Open or Resolved) 5.2(1) 5.2(2) O R Severity 4 CSCtn68418 Resolved Caveats • CSCtq76711 Symptom: The 8-port FCoE module (DS-X9708-K9) fails to boot up after it is power cycled.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m This symptom might be seen when a switch is downgraded from Cisco NX-OS Release 5.1(x) or Release 5.2(1) to NX-OS Release 4.2(x), and there is no Call Home configuration in the startup configuration. Workaround: This issue is resolved. • CSCtt02102 Symptom: The feature manager is not responsive and goes into a loop.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m 5 5 5 2 2 2 sb_part.0.0.0 sb_part.0.0.1 sb_part.0.0.2 12350000 Jan 12 11:54 12350100 Jan 12 11:54 12350200 Jan 12 11:54 This symptom might be seen because after packet decompression of a corrupted packet, the source of the packet is unknown and FCIP is unable to retrieve the FCIP header, SOF, or EOF. FCIP returns SYNC LOSS, which flaps the FCIP link. Workaround: This issue is resolved.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCtr52721 Symptom: On the 48-port 8-Gbps Advanced Fibre Channel switching module (DSX9248-256K9), port monitoring and alarms for Tx and Rx traffic can get disabled under some conditions for ports that have their speed set as “switchport speed auto.” Workaround: This issue is resolved.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m This symptom was seen because the Call Home feature had duplicate message throttling disabled and there were flapping interfaces that generated thousands of Call Home messages. These messages filled up the ISAN directory. Workaround: This issue is resolved.
Related Documentation Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m Workaround: Use CFS regions if a large number (greater than 512) of application flows need to be configured. CFS regions segment the FCR peer topology into manageable proportions. • CSCtr29423 Symptom: Tape acceleration is not working with the Emulex CNA card.
