Determining the Software Version
Note We strongly recommend that you use the latest available software release for all Cisco MDS 9000 Family products.
To determine the version of the Cisco SAN-OS software currently running on a Cisco MDS 9000 Family switch, log in to the switch and enter the show version EXEC command.
Feature Set
This Cisco MDS SAN-OS Release 1.0(3a) software is packaged in feature sets (also called software images) depending on the platform. The Cisco MDS SAN-OS software feature sets available for the Cisco MDS 9000 Family include Ethernet, Fibre Channel (1 Gbps and 2 Gbps), SNMP, and IP packets.
New Features in Release 1.0(3a)
SAN-OS Release 1.0(3a) is a maintenance release for switches in the Cisco MDS 9000 Family. See the "Caveats" section for details on closed and outstanding caveats and limitations.
Upgrading from Prior Releases to Release 1.0(3a)
To perform a quick, one-step upgrade on a Cisco MDS 9000 Family switch, follow these steps:
Step 1 Copy the kickstart and system image files to the required location (see Chapter 3, "Initial Configuration" in the Cisco MDS 9000 Family Configuration Guide).
Step 2 Set the boot variables (see Chapter 5, "Software Images" in the Cisco MDS 9000 Family Configuration Guide).
Step 3 Issue the reload command. The reload command reboots the system. This upgrade is disruptive.
Replaced Commands
•The install module slot# bios command replaces the following commands:
–bios verify
–bios program
–bios validate
•The install module slot# of the supervisor module loader command replaces the init bootloader command
New Command
The install all command upgrades all modules in any Cisco MDS 9000 Family switch. The install all command is only effective on switches running Cisco MDS SAN-OS Release 1.0(3a) and above.
See the Cisco MDS 9000 Family Configuration Guide.
Fabric Manager
You can monitor domain area ports and configure persistent FCIDs from the Fabric Manager and the Device Manager.
See the Cisco MDS 9000 Fabric Manager User Guide for further information.
Before you can create persistent FCIDs, you must:
•Configure a static domain ID in that VSAN
•Ascertain that the static configured domain and the runtime domain are the same. You can verify this using the show fcdomain command. For information about using the command line interface (CLI). See the Cisco 9000 Family Configuration Guide.
Limitations and Restrictions
The following limitations and restrictions apply to all switches in the Cisco MDS 9000 Family.
Static Domains and Persistency
When configuring FC domains, follow these guidelines:
•The fcdomain restart command applies your changes to the runtime settings. You can apply most of the configurations to their corresponding runtime values by using the restart disruptive option.
You must issue the fcdomain restart command if you want to apply the configured domain changes to the runtime domain.
•The configured domain ID can be preferred or static. By default, the configured domain is 0 and the configured option is preferred. If you do not configure a domain ID, the local switch sends a random ID in its request.
A static domain is specifically configured by the user and may be different from the runtime domain. If the domain IDs are different, the runtime domain ID will change to take on the static domain ID after the next restart.
•By default, the persistent FC ID feature is disabled. The assigned FC IDs in a fcdomain can be activated to remain persistent even after a reboot. This ensures that an attached N Port receives the same FC ID after a switch reboot.
If you connect to the switch from an AIX or HP-UX host, be sure to enable the persistent FC ID feature in the VSAN that connects these hosts.
•When enabling persistent domain IDs, once the VSAN is restarted, if the requested domain ID is not granted by the principal switch, all local interfaces in VSAN 55 are moved to an isolated state.
See the Cisco MDS 9000 Family Configuration Guide.
The install all Command
The install all command is only effective on switches running Cisco MDS SAN-OS Release 1.0(3a) and above.
See the Cisco MDS 9000 Family Configuration Guide.
VSANs in a Switch
Up to 256 VSANs can be configured in a switch. Of these, one is a default VSAN (VSAN 1), and another is an isolated VSAN (VSAN 4094). User-specified VSAN IDs range from 2 to 4093.
Console Severity Level
When logging is enabled for a console session (default), you can configure the severity levels of messages that appear on the console. The default severity for console logging is 2 (critical).
The current critical (default) logging level is maintained, if the console baud speed is 9600 baud (default). All attempts to change the console logging level generates an error message. T o increase the logging level (above critical), you must change the console baud speed to 38400 baud.
See the Cisco MDS 9000 Family Configuration Guide.
Initial Setup
The first time that you access a switch in the Cisco MDS 9000 Family, it runs a setup program that prompts you for the IP address and other configuration information necessary for the switch to communicate over the supervisor module Ethernet interface. Additionally, you can access the switch setup using the setup command in EXEC mode.
When accessing the switch setup you have the following additional capabilities:
•Type Ctrl-c at any prompt to skip the remaining configuration options and proceed with what is configured until that point.
•If you do not wish to answer a previously-configured question, or if you wish to skip answers to any questions press Enter. If a default answer is not available (for example switch name), the switch uses what is previously configured and skips to the next question.
Caveats
This section lists the caveats and corrected caveats for this release. Use Table 3 to determine the status of a particular caveat. In the table, "R" indicates a resolved caveat, and "O" indicates an open caveat.

Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz62706
•CSCdz49589
Symptom: In the Cisco Fabric Manager, when you right click on a standby supervisor module and select Reset, the standby supervisor module powers-down instead of power-cycling.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz49589
•CSCdz30806
Symptom: When you copy a file from active bootflash: to standby bootflash: and if the space available on standby bootflash: is insufficient to store the copied file, the copy command may report a success even though the file has not been copied to standby bootflash:.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz30806
Workaround: None.
•CSCdz36297
Symptom: If the standby supervisor bootflash does not have sufficient space for a new image, auto synchronization fails. This failure leaves a partial image file on the standby bootflash.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz36297
•CSCdz41227
Symptom: When you enter the IP address for the FC analyzer, save the configuration, and reboot the switch you will loose the remote capture configuration.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz41227
•CSCdz73481
Symptom: Cisco MDS 9000 Family switches support multi-pid RSCN from 1.0(2a). In some cases, it may send out more than one SW-RSCN, when the option is turned on for the same event (port_online).
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz73481
•CSCdz73186
Symptom: When interoperating using a Cisco MDS 9000 Family switch and a Brocade 3900 switch, the zonesets on the MDS switch and Brocade 3900 switch may be out-of-sync due to a non-standard timeout used by the 3900 device.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz73186
•CSCdz62711
Symptom: The boot variable image does not check platform compatibility. This is an enhancement request.

Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz62711
•CSCdz81955
Symptom: CLI command output attachment in XML Call Home messages are not XML encoded. In most cases it does not cause problems, as the special characters (which should be used with appropriate encoding, for example: > or <) do not appear in CLI command output. In some cases where stack traces are attached (as a result of a process crash), the CLI command output may contain these characters. These characters break the XML parsing in the back end.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz81955
•CSCdz76025
Symptom: SW-RSCN frames sent by the switch may contain non-zero values in the reserved field. While this field is ignored by the receiving Cisco MDS 9000 Family switches, other vendor switches may respond otherwise.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz76025
•CSCdz38248
Symptom: SyslogServerAddressType setting is not preserved across switch resets, when configured using the Cisco Device Manager.

•CSCdy77777
Symptom: When a fcsDiscoveryCompleteNotify trap is received through the nlmLog table, the fcsVsanDiscoverName is missing.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdy77777
•CSCdz40221
Symptom: Using the Device Manager or the Fabric manager, administrators can download an image to slot0 even though there is no flash in slot0.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz40221
•CSCdz29899
Symptom: FLOGI ACC(s) sent out on FL ports are not spanned.
If an FL port is configured as a SPAN source, the FLOGI accepts that leave this FL port are not spanned to the SPAN destination.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz29899
•CSCdz80007
Symptom: After rebooting and performing a switchover on a dual supervisor switch, it is possible that a VSAN may display an up operational state even if that VSAN may not contain any ports or if none of the ports in that VSAN are up.
This can cause the Fabric Manager to continuously try fabric discovery on this VSAN and to ultimately timeout with an error.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz80007
•CSCea04957
Symptom: When you issue a show running-config, the following message may be displayed: snmp-server host 10.144.132.174 traps version 2c public udp-port 2162 snmp-server host 10.144.132.174 traps version 2c public udp-port 2162 snmp-server host 10.144.132.174 traps version 2c public udp-port 2162 snmp-server host 10.144.132.174 traps version 2c public udp-port 2162
Enter Ctrl-C to exit this message.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCea04957
•CSCea43130
Symptom: An excessively busy boot flash on a standby supervisor could trigger the active supervisor to shut the standby supervisor down. This is because the standby supervisor cannot respond in time to the periodic health monitoring messages sent by active supervisor.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCea43130
Open Caveats
•CSCdz31332
Symptom: If automatic image synchronization is enabled, and the standby supervisor module is synchronizing the image from the active supervisor, the switch won't stop the user from issuing the reload command on the active or standby supervisor modules. This may result in a failure to synchronize the images.
Workaround: Be sure to allow sufficient time for the images to be synchronized before reloading a supervisor module.
•CSCei25319
Sympton: An error message in the log file occurs because the platform manager component passes the wrong parameter while responding to a SNMP query. In some cases, this results in the query not being responded to.
Workaround: Perform a refresh on Device Manager to clear the problem.
•CSCdy71186
Symptom: When you bring down a range of FL ports, there is a delay of four (4) seconds. This problem does not affect switch operation.
Workaround: None.
•CSCdz41155
Symptom: The show logging level command does not display the configured levels for some MDS services like system manager, RDL, and FLOGI.
Workaround: None.
•CSCdz42325
Symptom: When the switch boots for the first time and you configure the initial setup dialogue, or if you issue the write erase command and then reboot the switch, the setup process creates the configuration based on the input that you provide for the configuration. If a command execution goes wrong at this stage, it displays the following error:
Error: There was an error executing at least one commandPlease verify the running configuration of the switch.In some cases, this error is not reported. For example, if an IP address is configured on the network, the error may not be reported.
Workaround: Verify that the applied config is accurate by issuing a show running-config command.
•CSCdz12179
Symptom: When the Fabric Manager or Device Manager is run through VPN or any NAT scheme, a generic error occurs while adding duplicate zone members from a VPN connection.
Workaround: None. If an error occurs while running through VPN/NAT, all errors will show up as generic errors without a detailed message describing the error.
•CSCdz67484
Symptom: The Ethereal decoder incorrectly decodes the A bit in the Common Service Parameters set as Normal, instead of Alternate BB_Credit Management.
Workaround: None. The trace must be interpreted correctly.
•CSCea40555
Symptom: During an install procedure, entering Ctrl-c returns a message saying that the install procedure cannot be interrupted, while Ctrl-z returns the prompt without any message. In either case, the install procedure continues.
Workaround: None.
•CSCdz43707
Symptom: The Fabric Manager or Device Manager reports an error for all operations if the switch is multihomed (both IPFC based in-band management and the out-of-band management interface are up) and the Fabric or Device Manager was started using the IP-FC address. Typically, you will see a notInTime window error in the Device Manager and all sets fail.
Workaround: If the switch is multihomed, then start the Fabric or Device Manager on the switch using the out-of-band address.
•CSCdz43106
Symptom: The counter values freeze if the Device Manager port monitor window has been up and running for a long time (overnight or a few days).
Workaround: Close the frozen Device Manager window and open a new session.
•CSCea47778
Symptom: If the switch time zone is not UTC (default), the expire option for the username command returns an error. If the expire option is not specified, the username command does not have this issue.
switch# show clockMon Mar 17 18:20:28 JST 2003switch(config)# username user1 password cisco expireexpiry date wrongWorkaround: While creating a user-account, temporarily change the time zone to UTC.
