Refer to the Cisco MDS 9000 SAN Extension over IP package fact sheet for more information.
Deprecated Features On-Demand Port Activation License On-demand ports allow customers to benefit from Cisco NX-OS Software features while initially purchasing only a small number of activated ports on 8-Gbps or 4-Gbps Cisco MDS 9100 Series Multilayer Fabric switches. As needed, customers can expand switch connectivity by licensing additional ports.
Limitations and Restrictions SNIA Common Information Model SNIA Common Information Model (CIM or cimserver) commands are no longer supported. CIM is supported in Cisco DCNM-SAN Release 5.2. The SMI-S agent that is installed on the Cisco DCNM-SAN server allows external application to access fabric and switch profiles as specified in SNIA CIM. For additional information, see the Cisco DCNM Release Notes, Release 5.2. IVR Non-NAT Mode IVR non-NAT mode is not supported in Cisco NX-OS Release 5.2(x).
Limitations and Restrictions • Configuring a Persistent FCID in an IVR Configuration with Brocade Switches, page 34 SME Quorum You cannot change the quorum or the SME master node during a master key rekey. If a change occurs during the smart card portion of the operation, the master key rekey operation will fail and must be repeated from the beginning. OUI Mismatch for SME Tape Targets If Cisco DCNM does not discover all expected tape targets, check the sme.log to identify an OUI mismatch.
Limitations and Restrictions prevented from performing configuration, clear, execute, and debug commands as before, however, they are allowed to perform show commands for all VSANs. The ability to execute the show command addresses the following: • In a network environment, users often need to view information in other VSANs even though they do not have permission to modify configurations in those VSANs.
Limitations and Restrictions Using a RSA Version 1 Key for SSH Following an Upgrade For security reasons, NX-OS Release 4.2(1b) does not support RSA version 1 keys. As a result, if you upgrade to NX-OS Release 4.2(1b) from an earlier version that did support RSA version 1 keys, and you had configured an RSA version 1 key for SSH, then you will not be able to log in through SSH following the upgrade. If you have an RSA version 1 key configured for SSH, before upgrading to NX-OS Release 4.
Limitations and Restrictions > > enable commit When you attempt to apply these commands in the ASCII configuration, the following commands fail: > > > no destination-profile testProfile transport-method email destination-profile testProfile transport-method http destination-profile testProfile http https://xyz.abc.com To work around this issue, issue these commands after the commit command.
Limitations and Restrictions VF_ID Value Value Description FF0h ... FFEh Vendor specific. FFFh Do not use as a Virtual Fabric Identifier. FEFh = 4079 Applying Zone Configurations to VSAN 1 In the setup script, you can configure system default values for the default-zone to be permit or deny, and you can configure default values for the zone distribution method and for the zone mode. These default settings are applied when a new VSAN is created.
Limitations and Restrictions Support for FCIP Compression Modes In Cisco NX-OS Release 4.2(1b) and later, FCIP compression mode 1 and compression mode 3 are not supported on the Cisco MSM-18/4 module and on the SSN-16 module. Saving Copies of the Running Kickstart and System Images After you upgrade to MDS NX-OS Release 4.
Caveats • SPAN - 1 session maximum PPRC Not Supported with FCIP Write Acceleration IBM Peer to Peer Remote Copy (PPRC) is not supported with FCIP Write Acceleration. Configuring a Persistent FCID in an IVR Configuration with Brocade Switches The following information is relevant if you have a fabric that consists of Cisco MDS 9000 switches and Brocade switches, and the Cisco MDS switches are running either NX-OS Release 4.x or Release 5.x and Brocade is running FOS higher than 6.x.

Caveats Table 17 Open Caveats and Resolved Caveats Reference (continued) NX-OS Software Release (Open or Resolved) NX-OS Software Release (Open or Resolved) 5.2(6b) 5.
Caveats Symptom: While trying to download Device Manager using a switch IP address, the URL displays an “http error 403” message for switches with a single supervisor, including the Cisco MDS 9222i switch, the Cisco MDS 9148 switch, and the Cisco MDS 9134 switch. This symptom might be seen on a Cisco MDS 9000 switch that is either running Cisco NX-OS Release 5.2(6) or that was upgraded from a release where this issue was not present. Workaround: This issue is resolved.
Caveats This symptom only occurs for the specific failure case of the active supervisor with a faulty link to the fabric. Workaround: This issue is resolved. • CSCuc91171 Symptom: Cisco NX-OS software fails to save the running configuration and the following error message appears: Service "fcns" failed to save its configuration This symptom only occurs after the configuration has been saved many times (approximately 500 times).
Caveats Symptom: Smart zoning guidelines are needed in the Cisco MDS 9000 Release Notes for Cisco MDS NX-OS Release 5.2(6). Workaround: This issue is resolved. • CSCub83043 Symptom: The IOA tune lrtp-retx-timeout command is not reinitialized after an IOA failure. This symptom can occur if the tune lrtp-retx-timeout command is set to a nondefault value and there is an IOA port software failure. The default for the tune lrtp-retx-timeout command is 2500 ms.
Caveats • CSCuc71618 Symptom: Zoned Fibre Channel attached devices are unable to communicate when the ACLTCAM space for zoning reaches its maximum allowed size. This symptom occurs only on the Generation 4 Cisco MDS 9000 32-port 8-Gbps Advanced Fibre Channel Switching Module (DS-X9232-256K9) and the Cisco MDS 9000 48-port 8-Gbps Advanced Fibre Channel Switching Module (DS-X9248-256K9). The symptom occurs in the presence of another ACLTCAM problem that happens repeatedly.
Caveats TBIRD_FWD_EBM_0_SER_PARITY_XXX : Informational TBIRD_FWD_EBM_0_PACK0_EPR_DROP : Informational TBIRD_FWD_EBM_1_PACK3_MISS_SOF : Informational TBIRD_FWD_EBM_1_PACK0_MISS_EOP : Informational TBIRD_FWD_EBM_1_PACK0_SF_TOO_SMALL : Informational These errors are reported when there are internal correctable conditions encountered during operation, and the corrective action is taken. They do not necessarily indicated a problem with the switch or module.
Caveats This symptom might be seen when the IP address is configured on the mgmt0 interface. Workaround: This issue is resolved. • CSCub92848 Symptom: Configuring the LDAP search map in the output of the show ldap-server groups command incorrectly shows “Serach map” which should be “Search map.” This symptom might be seen when configuring LDAP on a Cisco MDS 9000 switch. Workaround: This issue is resolved. • CSCtz91659 Symptom: The show tech port-channel command should include additional outputs.
Caveats If more than one peer is affected by this issue, then additional steps are needed. If the application flows do not come online, then the application CLI commands need to be checked to verify that the flows did not get deleted. If they did, then the flows need to be recreated again through the application CLI command s or Cisco DCNM-SAN interface.
Caveats Symptom: After creating an SME cluster in advanced mode, adding 500 disks to the disk group, exporting the keys, and importing the keys again, there is no scroll option in the import manage key window. Workaround: None.
