Software Download Process

Use the software download procedure to upgrade to a later version, or downgrade to an earlier version, of an operating system. This section describes the software download process for the Cisco MDS NX-OS software and includes the following topics:

Determining the Software Version

To determine the version of Cisco MDS NX-OS or SAN-OS software currently running on a Cisco MDS 9000 Family switch using the CLI, log in to the switch and enter the show version EXEC command.

To determine the version of Cisco MDS NX-OS or SAN-OS software currently running on a Cisco MDS 9000 Family switch using Cisco DCNM for SAN, view the Switches tab in the Information pane, locate the switch using the IP address, logical name, or WWN, and check its version in the Release column.

Determining Software Version Compatibility

Table 10 lists the software versions that are compatible in a mixed SAN environment, the minimum software versions that are supported, and the versions that have been tested. We recommend that you use the latest software release supported by your vendor for all Cisco MDS 9000 Family products.

Table 10 Software Release Compatibility

NX-OS Release 4.2(3) and later

SAN-OS Release 3.3(5) or later

SAN-OS Release 3.3(5) and later

Downloading Software

The Cisco MDS NX-OS software is designed for mission-critical high-availability environments. To realize the benefits of nondisruptive upgrades on the Cisco MDS 9500 Directors, we highly recommend that you install dual supervisor modules.

To download the latest Cisco MDS NX-OS software, access the Software Center at this URL:

http://www.cisco.com/cisco/software/navigator.html?a=a&i=rpm

See the following sections in this release note for details on how you can nondisruptively upgrade your Cisco MDS 9000 switch. Issuing the install all command from the CLI, or using Cisco DCNM for SAN to perform the downgrade, enables the compatibility check. The check indicates if the upgrade can happen nondisruptively or disruptively depending on the current configuration of your switch and the reason.

Compatibility check is done:
Module bootable Impact Install-type Reason
------ -------- -------------- ------------ ------
1 yes non-disruptive rolling
2 yes disruptive rolling Hitless upgrade is not supported
3 yes disruptive rolling Hitless upgrade is not supported
4 yes non-disruptive rolling
5 yes non-disruptive reset
6 yes non-disruptive reset
 

At a minimum, you need to disable the default device alias distribution feature using the no device-alias distribute command in global configuration mode. The show incompatibility system bootflash: system image filename command determines which additional features need to be disabled.

NPE Software Images

No payload encryption (NPE) images are available with Cisco MDS NX-OS Release 6.2(5) software. The NPE images are intended for countries who have import restrictions on products that encrypt payload data.

To differentiate an NPE image from the standard software image, the letters npe are included in the image name as follows:

  • m9500-sf3ek9-kickstart-mz-npe.6.2.5.bin
  • m9500-sf3ek9-mz-npe.6.2.5.bin

When downloading software, ensure that you select the correct software images for you Cisco MDS 9000 Series switch. Nondisruptive software upgrades or downgrades between NPE images and non-NPE images are not supported.

Upgrading Your Cisco MDS NX-OS Software Image

This section lists the guidelines recommended for upgrading your Cisco MDS NX-OS software image and includes the following topics:


NoteBefore you begin the upgrade process, review the list of chassis and modules that Cisco MDS NX-OS Release 6.2(5) supports. See the“MDS 9000 Chassis and Module Support” section.


For detailed instructions for performing a software upgrade using Cisco DCNM, see the Cisco DCNM Release Notes, Release 6.2 , which is available from the following website:

http://www.cisco.com/en/US/products/ps10495/prod_release_notes_list.html

General Upgrading Guidelines

Before upgrading your Cisco NX-OS software, you must determine if the following issue has occurred in your switch:

%FLOGI-1-MSG_FLOGI_REJECT_FCID_ERROR after upgrade/switchover
 

An ISSU or ISSD involves a supervisor switchover, so it is very important that you determine if this issue is present before a supervisor switchover occurs. If this issue is detected before the supervisor switchover, the affected interfaces can be restored easily by entering the shutdown and no shutdown command sequence.

The following example shows how to determine if the issue has occurred before a supervisor switchover:

switch# show flogi internal info | i key|Interface | i key p 1
Interface fc4/32: mode[F] [119f000] Mode: F State: UP Vsan: 237
Vsan no:237 Max flogi key:0x1002a(65578) num_fl[0x1]<<<Max flogi key greater than 65535
--
Interface fc6/32: mode[F] [129f000] Mode: F State: UP Vsan: 237
Vsan no: 237 Max flogi key: 0x1(1) num_fl[0x1]
--

Look for the value for a Max flogi key that is greater than 65535.

In the example, the fc4/32 interface has encountered this issue, but the fc6/32 interface is normal.

If you see that an interface has a Max flogi key greater than 65535 before a system switchover, ISSU, or ISSD, you must disable the interface and then reenable it by using the shutdown command followed by the no shutdown command. This process disrupts the devices on the interface that is being shut down. After the devices relogin, the Max flogi key is reset to 1 and you can avoid this issue.

If an install and/or ISSU, or supervisor switchover has occurred, compare the number of devices fabric login (FLOGI) with the number of devices in the Fibre Channel Name Server (FCNS) local database. Enter the show flogi database and the show fcns database local commands and use the CLI outputs for comparison. If the FLOGI database has fewer entries than the FCNS local database, the issue has occurred.

Also, if the following error message appears after an install, ISSU, or supervisor switchover, the issue might bug may have been encountered:

%FLOGI-1-MSG_FLOGI_REJECT_FCID_ERROR: %$VSAN xxx%$ [VSAN xxx, Interface fc4/19: mode[F]] FLOGI rejected - FCID allocation failed with error 0x401b0000.
 

If you observe either of the above situations, open a case with the Cisco TAC.


NoteIf the Max flogi key value is a large number and is incrementing, it indicates that a device is repeatedly logging in. This situation might be a separate problem that needs further investigation. For assistance, contact the Cisco TAC.


In addition, follow these general guidelines before performing a software upgrade:

  • Review the nondisruptive upgrade path to Release 6.2(5) in Table 16 .
  • Install and configure dual supervisor modules before the upgrade.
  • Issue the show install all impact upgrade-image CLI command to determine if your upgrade will be nondisruptive.
  • Be aware that some features impact whether an upgrade is disruptive or nondisruptive:

Fibre Channel Ports : Fibre Channel ports can be nondisruptively upgraded without affecting traffic on the ports. See Table 16 for the nondisruptive upgrade path for all NX-OS and SAN-OS releases.

Gigabit Ethernet Ports : Traffic on Gigabit Ethernet ports is disrupted during an upgrade or downgrade. This includes IPS modules and the Gigabit Ethernet ports on the MSM-18/4 module and the MDS 9222i and MDS 9250i switch. Those nodes that are members of VSANs traversing an FCIP ISL are impacted, and a fabric reconfiguration occurs. iSCSI initiators connected to the Gigabit Ethernet ports lose connectivity to iSCSI targets while the upgrade is in progress.

FICON : If you have FICON enabled, the upgrade path is different. See the “FICON Supported Releases and Upgrade Paths” section.


NoteIn addition to these guidelines, you may want to review the information in the“Limitations and Restrictions” section prior to a software upgrade to determine if a feature may possibly behave differently following the upgrade.


Nondisruptive Upgrade Paths

Use Table 16 to determine your nondisruptive upgrade path to Cisco MDS NX-OS Release 6.2(5). Find the image release number you are currently using in the “Current Release” column of the table and follow the steps in the order specified to perform the upgrade.


NoteThe software upgrade information inTable 16 applies only to Fibre Channel switching traffic. Upgrading system software disrupts IP traffic and intelligent services traffic.

Downgrading Your Cisco MDS SAN-OS Software Image

This section lists the guidelines recommended for downgrading your Cisco MDS SAN-OS software image and includes the following topics:

General Downgrading Guidelines

Follow these general guidelines before you perform a software downgrade:

  • Issue the system no acl-adjacency-sharing execute command to disable ACL adjacency usage on Generation 2 and Generation 1 modules. If this command fails, reduce the number of zones, IVR zones, TE ports, or a combination of these in the system and issue the command again.
  • Disable all features not supported by the downgrade release. Use the show incompatibility system downgrade-image command to determine what you need to disable.
  • Use the show install all impact downgrade-image command to determine if your downgrade will be nondisruptive.
  • Be aware that some features impact whether a downgrade is disruptive or nondisruptive:

Fibre Channel Ports : Fibre Channel ports can be nondisruptively downgraded without affecting traffic on the ports. See Table 19 for the nondisruptive downgrade path for all SAN-OS releases.

Gigabit Ethernet Ports : Traffic on Gigabit Ethernet ports is disrupted during a downgrade. This includes IPS modules and the Gigabit Ethernet ports on the MSM-18/4 module, and the MDS 9222i switch. Those nodes that are members of VSANs traversing an FCIP ISL are impacted, and a fabric reconfiguration occurs. iSCSI initiators connected to the Gigabit Ethernet ports lose connectivity to iSCSI targets while the downgrade is in progress.

FICON : If you have FICON enabled, the downgrade path is different. See the “FICON Downgrade Paths” section.

Use Table 19 to determine the nondisruptive downgrade path from Cisco NX-OS Release 6.2(5). Find the NX-OS or SAN-OS image that you want to downgrade to in the To SAN-OS Release column of the table and follow the steps in the order specified to perform the downgrade.


NoteThe software downgrade information inTable 19 applies only to Fibre Channel switching traffic. Downgrading system software disrupts IP and intelligent services traffic.

Licensed Cisco NX-OS Software Packages

Most Cisco MDS 9000 family software features are included in the standard package. However, some features are logically grouped into add-on packages that must be licensed separately, such as the Cisco MDS 9000 Enterprise package, SAN Extension over IP package, Mainframe package, and Data Mobility Manager package. On-demand ports activation licenses are also available for the Cisco MDS 9250i Multiservice Fabric Switch, Cisco MDS 9148 48-Port Multilayer Fabric Switch, and the Cisco MDS 8-Gb Fabric Switch for HP c-Class Blade System.


NoteA license is not required to use the Cisco MDS 9000 8-port 10-Gbps Fibre Channel over Ethernet (FCoE) module (DS-X9708-K9).


Additional information about licensed Cisco NX-OS software packages is available at this URL:

http://www.cisco.com/en/US/partner/products/ps6029/products_data_sheets_list.html

Enterprise Package

The standard software package that is bundled at no charge with the Cisco MDS 9000 Family switches includes the base set of features that Cisco believes are required by most customers for building a SAN. The Cisco MDS 9000 family also has a set of advanced features that are recommended for all enterprise SANs. These features are bundled together in the Cisco MDS 9000 Enterprise package. Refer to the Cisco MDS 9000 Enterprise package fact sheet for more information.

SAN Extension over IP Package

The Cisco MDS 9000 SAN Extension over IP package allows the customer to use FCIP to extend SANs over wide distances on IP networks using the Cisco MDS 9000 family IP storage services. Refer to the Cisco MDS 9000 SAN Extension over IP package fact sheet for more information.

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. Refer to the Cisco MDS 9000 Mainframe package fact sheet for more information.

Data Mobility Manager Package

The Cisco MDS 9000 Data Mobility Manager package enables data migration between heterogeneous disk arrays without introducing a virtualization layer or rewiring or reconfiguring SANs. Cisco DMM allows concurrent migration between multiple LUNs of unequal size. Rate-adjusted migration, data verification, dual Fibre Channel fabric support, and management using Cisco DCNM for SAN provide a complete solution that greatly simplifies and eliminates most downtime associated with data migration. Refer to the Cisco MDS 9000 Data Mobility Manager package fact sheet for more information. The Data Mobility Manager package is for use only with Cisco MDS 9000 Family switches.

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 the Cisco MDS 9250i Multiservice Fabric Switch, MDS 9148 48-Port Multilayer Fabric Switch, and the Cisco MDS 8-Gb Fabric Switch for HP c-Class Blade System. As needed, customers can expand switch connectivity by licensing additional ports.

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. The number of licenses required is equal to the number of service engines on which the intelligent fabric application is used.The SSN-16 requires a separate license for each engine on which you want to run IOA. Each SSN-16 engine that you configure for IOA checks out a license from the pool managed at the chassis level. SSN-16 IOA licenses are available as single licenses.

XRC Acceleration License

The Cisco Extended Remote Copy (XRC) acceleration license activates FICON XRC acceleration on the Cisco MDS 9222i switch and on the MSM-18/4 in the Cisco MDS 9500 Series directors. One license per chassis is required. You must install the Mainframe Package and the SAN Extension over FCIP Package before you install the XRC acceleration license. The Mainframe Package enables the underlying FICON support, and the FCIP license or licenses enable the underlying FCIP support.

Deprecated and Changed Features

Zoning Features

LUN zoning, read-only zones, and broadcast zones are no longer supported. These features affect the following hardware:

  • Cisco MDS 9250i Multiservice Fabric Switch
  • Cisco MDS 9000 8-port 10-Gbps Fibre Channel over Ethernet (FCoE) module

Limitations and Restrictions

This section lists the limitations and restrictions. The following limitations are described:

FCoE on the Cisco MDS 9710 Director

The Cisco MDS 9710 Director does not support FCoE. However, the following command-line interface (CLI) commands display information about FCoE, even though the FCoE functionality does not work on the Cisco MDS 9710 switch:

  • The show feature-set command shows the FCoE feature set enabled.
  • The show fcoe command shows FCoE FCF details.
  • In global configuration mode, the fcf argument to the fcoe command can be modified.
  • The vlan vlan-number command allows the VLAN to be created.
  • The show vlan command shows VLAN information.

FCoE vlan-vsan map creation through SNMP is allowed.

FCoE can be enabled or disabled through SNMP.

ASCII File Can Be Copied to the Startup Configuration

The copy bootflash:runnig-config.ascii startup-config command that was deprecated in an earlier Cisco NX-OS release is enabled from Cisco NX-OS Release 6.2(1).

Fibre Channel Security Protocol (FC-SP) Not Supported

Cisco NX-OS Release 6.2(1) does not support the Fibre Channel Security Protocol (FC-SP) feature only on the Cisco MDS 9710 Director.

Install Module Command Changes

The install module module-number bios command is not supported on the Cisco MDS 9710 switch in Cisco NX-OS Release 6.2(1) and later releases. Use the install all command to upgrade the BIOS during a software upgrade.

The install module module-number bios command continues to be supported in Cisco NX-OS Release 6.2(1) on Cisco MDS 9500 Series switches.

Fabric Binding Error Message

When fabric binding is enabled, an error message appears whenever the Mainframe Package license is not installed and also when the grace period is disabled. There is functional impact associated with the error message and the feature is enabled correctly.

Resolved Caveats

  • CSCtz92415

Symptom: The zone server crashes with the following error:

%SYSMGR-2-SERVICE_CRASHED: Service "zone" (PID 2573) hasn't caught signal 6 (core will
be saved).
 

Condition: This situation occurs during a normal operation.

Workaround: This issue is resolved.

  • CSCui26277

Symptom: When a leap second adjustment occurs on the Network Time Protocol (NTP) server, multiple symmetrix ports that run Symmetrix Remote Data Facility (SRDF) connected to the Storage Services Module (SSM) modules experience traffic disruption with the following error:

FCP_CNTR_LAF_C3_TIMEOUT_FRAMES_D
FCP_CNTR_MAC_C3_TIMEOUT_FRAMES_D
 

Condition: This issue occurs during a normal operation.

Workaround: This issue is resolved.

More Information: The show logging onboard command does not display information about this error.

  • CSCum21081

Symptom: When Cisco MDS switches are upgraded to or running Cisco MDS NX-OS Software Release 6.2(1) or 6.2(3), the Fibre Channel over IP (FCIP) tunnel throughput is reduced considerably. Devices that use these FCIP tunnels might experience latency issues and application outages.

Condition: This issue applies to FCIP tunnels on 16-Port Storage Services Node (SSN16) (DS-X9316-SSNK9) modules only.

Workaround: This issue is resolved.

Open Caveats

  • CSCug22090

Symptom : When an ISSU occurs from Cisco NX-OS Release 5.2(6b) to Release 6.2(1), LLDP command-line interface (CLI) commands are not available. In this situation, LLDP is running and traffic is flowing normally even after the ISSU, but the CLI commands are not available.

This symptom might be seen when feature-set fcoe was enabled on the original image, and feature lldps commands were working in the original image. Following the ISSU to Cisco NX-OS Release 6.2.1 image, the commands are not available.

Workaround : Following the ISSU, enter the feature lldp command on the switch to make the LLDP commands available on the switch.

switch(config)# feature lldp
switch(config)# show lldp ?
 
  • CSCtr50223

Symptom : On the MDS 9513 switch, when an MSM-18/4 module boots up, it sends a request to the supervisor module to mount the modflash on the MSM-18/4 module. If there is a timeout or error in response, the following syslog message displayed:

2011 Jul 14 01:18:13 sw-dc5-br2-12 %LC_MNT_MGR-SLOT3-2-LC_MNT_MGR_ERROR: SUP mount failed. MTS receive timedout
2011 Jul 14 01:19:06 sw-dc5-br2-12 %PROC_MGR-SLOT3-2-ERR_MSG: ERROR: PID 1144 (lc_mnt_mgr) exited abnormally, exit status (0xa)
2011 Jul 14 01:19:06 sw-dc5-br2-12 %MODULE-2-MOD_MINORSWFAIL: Module 3 (serial: JAE1141ZB43) reported a failure in service lc_mnt_mgr
 

This issue might be seen when the supervisor module is unusually busy and cannot process the mount request from the MSM-18/4 module, or the actual mount command on the supervisor takes a long time.

Workaround : Reload the MSM-18/4 module in the same slot/module where the modflash mount failed. A request will be sent to the supervisor to mount the modflash.

  • CSCug14717

Symptom : If beaconing is configured on some ports, they might stop blinking after a supervisor switchover or module reload.

Condition: This might be seen following a supervisor switchover or module reload.

Workaround : None.

  • CSCub40020

Symptom: After an In Service Software Upgrade (ISSU), In Service Software Downgrade (ISSD), or supervisor switchover, devices fail to FLOGI into the switch, and the following error is logged in the syslog:

%FLOGI-1-MSG_FLOGI_REJECT_FCID_ERROR after upgrade/switchover

Condition: This situation occurs if one or all of the following occur:

1. The Max flogi key is greater than 65535. The key can get this high if there are repeated FLOGIs on an interface. After the key exceeds 65535, this issue occurs. However, this situation does not impact end devices.

2. If a supervisor switchover, such as ISSU, ISSD, or system switchover occurs when the key is greater than 65535, Fibre Channel Identifiers (FC IDs) can be dropped from the FLOGI table. The end devices continue to function normally until they are logged out and then attempt to relogin.

3. If after both 1 and 2 above have occurred and then an end device is rebooted on the affected interface, that end device might not be able to log back in.

Workaround: You must first resolve the issue with the device on the interface with the Max flogi key over 65535, such as FLOGI rejects or port security, to prevent the FLOGI key from incrementing.

If the Max flogi key value is greater than 65535 before any supervisor switchover, ISSU, or ISSD, use the shutdown and then no shutdown command on the interface. Consequently, the Max flogi key value must be checked before any supervisor switchover. However, if the supervisor switchover has already occurred and logging in are failing, you must follow either of these steps:

Contact Cisco TAC to implement a nondisruptive recovery. This requires special files not accessible to customers.

Suspend the VSAN and wait for 5 minutes and then unsuspend the VSAN of the affected devices on the switch. This action is disruptive to all devices in that VSAN connected to this switch.

More Information: For detailed information about this issue, see the General Upgrading Guidelines.

  • CSCuh49283

Symptom: One of the symptoms are observed:

A zone member goes offline.

A Registered State Change Notification (RSCN) is not sent to zone members.

The device-mapping entry, port world wide name (pWWN) associated to a device alias is not displayed in the Dynamic Port VSAN Membership (DPVM) database

The show running-configuration ivr command does not display the changes when a device alias member in an Inter-VSAN routing zone (IVR zone) is renamed.

The port world wide name (pWWN) associated with the device alias is found dissociated in the port security database.

A device alias member is not found in the port security database.

Condition: This situation occurs when all or one of the conditions is met:

A user attempts to perform a device-alias operation in batch, such as renaming an offline device alias to an existing online device alias or vice versa.

A device alias was renamed.

A device alias was deleted and an existing device alias is renamed to the deleted device alias in the same commit.

A device alias, which is not configured, resides in the DPVM database and an online device is renamed to the former.

The IVR distribute option is enabled and the device alias is in enhanced mode, and the changes in a device alias is not updated to the IVR running configuration.

Workaround: Add the offline member to the device alias database, revert to the previous name if you have renamed a device alias, and flap the ports that are connected to the affected zone member.

  • CSCui16928

Symptom: Although the http-server feature is enabled by default, Element Manager cannot be downloaded.

Condition: This situation occurs on the Cisco MDS 9710 Director running MDS NX-OS Release 6.2(3) software.

Workaround: You must enable the HTTP server by using the feature http-server command.

  • CSCud07594

Symptom : In a virtual SAN (VSAN), the inter-switch link (ISL) might fail after entering the suspend command, followed by the no suspend command.

Condition: This situation occurs if the no suspend command is entered after a VSAN suspend operation.

Workaround: After entering the suspend command, wait at least from 5 to 15 minutes and then use the no suspend command.

  • CSCuj94303

Symptom: Traffic between two Cisco MDS 9250i switches might stop when write acceleration is enabled during a traffic flow.

Condition: This situation occurs if there are more than 11 tunnels.

Workaround: Disable the write acceleration feature on all of the tunnels or move all tunnels in a port channel.

  • CSCul13809

Symptom: Several control protocols are impacted because of the FCoE data traffic congestion in the traffic flows passing through or originating or terminating on a Cisco MDS 9250i switch that runs the default 7e network-qos policy.

Condition: This is a known limitation with 7e policy. With the 7e template, all control and data FCoE traffic is sent to a single queue. When congestion in the network is present, in addition to data packets, control packets also are impacted, which results in timeouts and drops for several control protocols. Control protocols might display errors.

Workaround: Use the 6e template throughout fabric so that control and data traffic are placed in different queues and do not impact each other.

  • CSCuo24658

Symptom: After a switch upgrade to NX-OS 6.2(1) or later, a previously working AAA authenticated user who is configured for non network-operator privileges (such as network-admin) only receives network-operator privileges. This user is no longer able to configure the switch via CLI or SNMP.

The CLI user will show as having 'network-operator' role:

switch# show user-account fieldsupport
user:fieldsupport
roles:network-operator

 

If the SNMP user exists, it will show as having 'network-operator' role:

switch# show snmp user fieldsupport
______________________________________________________________
SNMP USERS
______________________________________________________________
User Auth Priv(enforce) Groups
____ ____ _____________ ______
fieldsupport md5 des(no) network-operator
 

Condition: This issue only affects logins that meet all of the following conditions:

1) are logins to MDS switches

2) are authenticated remotely via RADIUS

3) have multiple vendor-specific attributes (VSAs) defined as a single Cisco-AV Pair, for example, shell and SNMP version 3 settings:

shell:roles="operations-user fieldsupport" snmpv3:auth=SHA priv=AES-128
 

This issue does not occur if the 'shell:roles' VSA is defined alone (even with multiple roles assigned).

Workaround: On the AAA server, create a separate RADIUS policy for NX-OS 6.2(x) users that splits Cisco-AV Pairs into true attribute pairs. For example:

Cisco-AVPair #1: shell:roles="operations-user fieldsupport
Cisco-AVPair #2: snmpv3:auth=SHA priv=AES-128
 

Assign this policy conditionally on the requesting RADIUS client IP address (that is, a Cisco MDS switch mgmt0 IP address). Continue to use the original policy with the old format for RADIUS authentication requests from switches running NX-OS earlier than 6.2(1).

If the RADIUS server does not support conditional assignment of policies by RADIUS client IP address then an alternate method is possible. Create a local user on the switch with local role assignment which will override the remotely supplied role using the following commands:

  • CSCul65496

Symptom: On the Cisco MDS 9250i switch, if the Transmission Control Protocol (TCP) connections are set to 5, tape acceleration cannot be enabled.

Condition: The tcp-connections command is used to set the TCP connection to 5.

Workaround: Set TCP connections to 2.

  • CSCuj42921

Symptom: Inserting and removing an SFP in quick succession might cause the read operation to fail before completion with NACK errors, and the searching for supported speeds fails. This situation might prevent a port from coming up and the following error appears:

speed not supported by transceiver
 

Condition: This situation occurs with specific SFPs during removal and reinsertion.

Workaround: Avoid quickly removing and inserting an SFP. After removing an SFP, wait for few seconds before reinserting it.

  • CSCuh93233

Symptom: The Switched Port Analyzer (SPAN) feature does not work after a member of a port channel is removed.

Condition: This situation occurs only when the monitor session source is a port channel.

Workaround: Restore the member in the port channel and then create a monitor session and add the port channel.

  • CSCuj68267

Symptom: The In-Service Software Upgrade (ISSU) or In-Service Software Downgrade (ISSD) of more than one Cisco MDS 9250i switch that are connected to one another might cause the VE/E links between them to go down.

Condition: This situation occurs if an ISSU or ISSD is simultaneously performed on Cisco MDS 9250i switches that are interconnected.

Workaround: Perform an ISSU or ISSD in a progressive method. For example, after the upgrade or downgrade completes on one switch, move on to another.

  • CSCuj77722

Symptom: On the Cisco MDS 9250i switch that is connected to a Cisco Nexus 5000 switch for virtual Fibre Channel links, an In-Service Software Upgrade (ISSU) operation becomes a disruptive process.

Condition: This situation occurs if the Cisco Nexus 5000 switch in Nport virtualization (NPV) mode is connected to the Cisco MDS 9250i switch and the host and or target is connected to the Cisco Nexus 5000 switch.

Workaround: Before an ISSU, set the FCoE fka-adv-period on the MDS 9250i switch to the maximum.

  • CSCuj83626

Symptom: If there is a Switched Port Analyzer (SPAN) session to inband and the switch is reloaded, the SPAN session becomes inactive, and packets are not spanned to the SPAN destination.

Condition: A Cisco MDS switch is reloaded when a SPAN session exists from an inband port.

Workaround: Delete the SPAN session and add the session again.

  • CSCuj99534

Symptom: During an In-Service Software Upgrade (ISSU) the Cisco MDS 9250i switch displays the following errors:

2013 Oct 10 14:09:07 sw234-9250i %ACLTCAM-2-ACL_TCAM_PHY_TCAM_WRITE_FAILED: Value write to hardware TCAM failed(ASIC: 1, Input TCAM, Address: 775, Num Entries: 1, Error: Broken pipe).
2013 Oct 10 14:09:07 sw234-9250i %ACLTCAM-2-ACL_TCAM_PHY_TCAM_WRITE_FAILED: Value write to hardware TCAM failed(ASIC: 2, Input TCAM, Address: 609, Num Entries: 1, Error: Broken pipe).
 

Condition: The Cisco MDS 9250i switch has 200 I/O Accelerator (IOA) disk flows.

Workaround: None.

More information: The Cisco MDS 9250i switch supports up to 180 disk flows.

  • CSCul08289

Symptom: The Cisco MDS 9250i switch displays a powered-off power supply module as redundant.

Condition: Two supply modules are operational and one is in powered off.

Workaround: Ensure that all three supply modules are operational.

  • CSCul46007

Symptom: For a Cisco MDS 9250i switch, an FCoE Ethernet Interface Monitor window displays Rx and Tx as 0.

Condition: This situation occurs when the interval for monitoring the Ethernet interface is set to 5 seconds in Data Center Network Manager (DCNM).

Workaround: Set the interval for monitoring an Ethernet interface to 10 or higher.

  • CSCuj42272

Symptom: On a Cisco MDS 9000 switch, when a fan fails, the board LED and fan LED turn red.

Condition: This situation occurs when one of the fans fails.

Workaround: None.

More information: If a fan LED and the board LED are red, it is a fan failure. If only the board LED is red, it indicates that shutdown is in progress because of an over temperature condition.

  • CSCup92981

Symptom: An operational FCIP tunnel resets randomly. The following type of syslog messages are seen:

%ETHPORT-5-IF_DOWN_SOFTWARE_FAILURE: Interface IPStorage1/2 is down (Port software failure)
%PORT-5-IF_DOWN_SOFTWARE_FAILURE: %$VSAN 1%$ Interface fcip2 is down (Port software failure)
 

Condition: This issue occurs only on the Cisco MDS 9250i switch if IP compression is enabled on an FCIP tunnel and data is being sent from the port. All IP compression modes are affected.

Workaround: Disable IP compression on both ends of the affected FCIP link.

  • CSCuf35479

Symptom : A Bad IPv6 host address error appears when the snmp-server hostname is configured instead of the IP address. This issue occurs when the domain name and the nameserver IP address are configured.

Workaround : Configure the IP addresses instead of the hostname.

  • CSCui21601

Symptom The Cisco MDS 9710 Director does not allow a copy running saving configuration and a switch reload operation.

Condition: Active Fibre Channel Redirect (FC-Redirect) configurations are present in Cisco MDS 9710 Director.

Workaround : Remove the Cisco MDS 9710 Director from the fabric.

  • CSCul12775

Symptom: The Cisco MDS 9250i switch incorrectly displays that the Ternary Content Addressable Memory (TCAM) is full even if enough memory is available.

Condition: This situation occurs when the IOA flows go into the security region and some TCAM entries are deleted and added.

Workaround: None.
