Cisco MDS 9000 Series Transceiver Firmware Release Notes, Release 9.4(1a)

 

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Introduction

Cisco MDS NX-OS Release 9.4(1) introduces transceiver firmware upgrade capability for supported transceivers on Cisco MDS 9000 platforms. The firmware upgrades are provided to enhance the performance of the transceivers and to resolve known issues.

A transceiver firmware bundle is a file containing updates for multiple transceivers. Each transceiver model firmware update bundle has its own version number. A transceiver firmware bundle may contain new updates for only some transceivers. Firmware for some transceivers may be the same version as the previous firmware bundle.

To download transceiver firmware bundles, go to NX-OS EPLD Updates folder under respective products from https://software.cisco.com/download/navigator.html.

Transceiver Firmware Support Matrix

The following table lists versions of Cisco MDS NX-OS used to install transceiver firmware bundles. The versions must match during installation, but Cisco MDS NX-OS versions can be subsequently upgraded or downgraded without changing the transceiver firmware versions.

Guidelines and Limitations

When you upgrade the Transceiver firmware, consider the following guidelines and limitations:

●     Transceiver firmware can only be upgraded. After the transceiver firmware is upgraded, it is compatible with all versions of Cisco MDS NX-OS.

●     Transceiver firmware upgrade is supported only for the transceivers that are mentioned in the transceiver firmware versions packaged in the transceiver firmware bundle.

●     Transceiver firmware upgrade is supported only on Cisco MDS 9000 platforms that are mentioned in the transceiver firmware Support Matrix.

●     Transceiver upgrade is a disruptive procedure. All interfaces, including those in the same module or fabric switch which are not undergoing upgrade will be shut down during the upgrade.

●     Do not run interface commands or open another upgrade session on the module or switch while the transceiver is upgrading. This may result in permanent damage to the transceivers.

Determining Transceiver Firmware Version

Use the show interface fcx/y transceiver details command to view the current version of firmware on a specific transceiver module. The version of firmware currently running on the transceiver is displayed on the "Firmware version is" line.

Transceiver Firmware Upgrade

This section contains the following topics:

●     Upgrading Transceivers Firmware

●     Upgrading Transceivers in Director Switches

●     Upgrading Transceivers in Fabric Switches

●     Cleaning a Previously Terminated Upgrade

When upgrading transceivers on MDS Director switches, all transceivers in all modules are upgraded by default, or optionally each single module is upgraded. When upgrading transceivers on MDS fabric switches, all supported transceivers will be upgraded together.

Warning: Transceiver firmware upgrade is a disruptive operation. All ports in the switch or line card will be shut down during the upgrade. If required by the specific upgrade, the switch or line card will be reloaded after the upgrade to complete the upgrade.

Upgrading Transceivers

To update firmware in upgradable transceivers, use the install transceiver command.

Optionally, the modules to be upgraded can be specified by the user using the module keyword. Use comma (,) or range separator (-) to specify a subset of modules. If a specified module number is not present or not supported, it will be ignored and the remaining valid modules will be upgraded. To update firmware on all supported transceivers in a Fabric switch, use the command without the module keyword.

Note:       As a fabric switch may reload after the upgrade, save any pending configuration before starting the upgrade. The upgrade will not proceed if there is any pending configuration in the show running-config diff command output.

If none of the transceivers require upgrading, the command exits. Otherwise, any transceivers with firmware version lower than the packaged version will be listed in a table and a prompt. The table displays the following details:

●     interface number

●     current firmware version

●     new firmware version

●     if reload is required

If you choose to continue, all the interfaces in the corresponding modules are shut down, and all listed transceivers are upgraded in the listed order. The upgrade process may take several minutes to complete. After the upgrade, the status of each upgraded transceiver module is again displayed in a table. If any transceivers must be power cycled, on a Director switch the corresponding modules are reloaded automatically. For a Fabric switch, the whole switch will reload automatically. After the modules or switch become online, the interfaces are operational.

switch#

Cleaning a Previously Terminated Upgrade

Accessing transceivers during an upgrade can cause permanent damage to them. To prevent any damage, only one upgrade session is permitted at a time. The following message is displayed when an attempt is made to start parallel upgrades.

switch# install transceiver bootflash:nxos-transceiver-firmware.mds.9.4.1a.bin

Already one active install transceiver session is in progress. Running parallel install transceiver session(s) are not allowed.

If you want to re-run install transceiver due to previously aborted session(if any), please run 'install transceiver clean' first to do clean up and try running install transceiver again.

switch#

If there are no parallel upgrade sessions are running, and the above message is from a previously terminated upgrade, use the install transceiver clean command to clear the session and run the install command again.

Example: Cleaning previously terminated transceiver upgrade

switch# install transceiver clean

switch#

Warning: Running this command clears the lock on any ongoing upgrade. The original upgrade process is not stopped and a subsequent upgrade will then be allowed, making the upgrade process likely to fail and cause transceiver damage. It is advised to use the install transceiver clean command only after an upgrade fails or terminates.

If an upgrade is terminated, wait for a few minutes for any ongoing upgrade to complete before attempting again. The approximate time required to complete each transceiver install session is displayed in the banner text before any upgrade process starts.

-----------------------------------------------------------------------------------------------

Transceiver firmware upgrade is a disruptive operation and all interfaces, including those interfaces that do not need upgrading in the respective line card(s), will be shutdown during the process. This will take approximately 00 hrs 15 mins to complete.

 

Any module with transceivers upgraded will be reloaded after the upgrade is finished.
